Summary
Apache Hadoop: Temporary File Local Information Disclosure
Details

Apache Hadoop’s RunJar.run() does not set permissions for temporary directory by default. If sensitive data will be present in this file, all the other local users may be able to view the content. This is because, on unix-like systems, the system temporary directory is shared between all local users. As such, files written in this directory, without setting the correct posix permissions explicitly, may be viewable by all other local users.

Summary
Local Temp Directory Hijacking Vulnerability
Details

Impact

On Unix like systems, the system's temporary directory is shared between all users on that system. A collocated user can observe the process of creating a temporary sub directory in the shared temporary directory and race to complete the creation of the temporary subdirectory. If the attacker wins the race then they will have read and write permission to the subdirectory used to unpack web applications, including their WEB-INF/lib jar files and JSP files. If any code is ever executed out of this temporary directory, this can lead to a local privilege escalation vulnerability.

Additionally, any user code uses of WebAppContext::getTempDirectory would similarly be vulnerable.

Additionally, any user application code using the ServletContext attribute for the tempdir will also be impacted. See: https://javaee.github.io/javaee-spec/javadocs/javax/servlet/ServletContext.html#TEMPDIR

For example:

import java.io.File;
import java.io.IOException;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class ExampleServlet extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        File tempDir = (File)getServletContext().getAttribute(ServletContext.TEMPDIR); // Potentially compromised
        // do something with that temp dir
    }
}

Example: The JSP library itself will use the container temp directory for compiling the JSP source into Java classes before executing them.

CVSSv3.1 Evaluation

This vulnerability has been calculated to have a CVSSv3.1 score of 7.8/10 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

Patches

Fixes were applied to the 9.4.x branch with: - https://github.com/eclipse/jetty.project/commit/53e0e0e9b25a6309bf24ee3b10984f4145701edb - https://github.com/eclipse/jetty.project/commit/9ad6beb80543b392c91653f6bfce233fc75b9d5f

These will be included in releases: 9.4.33, 10.0.0.beta3, 11.0.0.beta3

Workarounds

A work around is to set a temporary directory, either for the server or the context, to a directory outside of the shared temporary file system. For recent releases, a temporary directory can be created simple by creating a directory called work in the ${jetty.base} directory (the parent directory of the webapps directory). Alternately the java temporary directory can be set with the System Property java.io.tmpdir. A more detailed description of how jetty selects a temporary directory is below.

The Jetty search order for finding a temporary directory is as follows:

  1. If the WebAppContext has a temp directory specified, use it.
  2. If the ServletContext has the javax.servlet.context.tempdir attribute set, and if directory exists, use it.
  3. If a ${jetty.base}/work directory exists, use it (since Jetty 9.1)
  4. If a ServletContext has the org.eclipse.jetty.webapp.basetempdir attribute set, and if the directory exists, use it.
  5. Use System.getProperty("java.io.tmpdir") and use it.

Jetty will end traversal at the first successful step. To mitigate this vulnerability the directory must be set to one that is not writable by an attacker. To avoid information leakage, the directory should also not be readable by an attacker.

Setting a Jetty server temporary directory.

Choices 3 and 5 apply to the server level, and will impact all deployed webapps on the server.

For choice 3 just create that work directory underneath your ${jetty.base} and restart Jetty.

For choice 5, just specify your own java.io.tmpdir when you start the JVM for Jetty.

[jetty-distribution]$ java -Djava.io.tmpdir=/var/web/work -jar start.jar

Setting a Context specific temporary directory.

The rest of the choices require you to configure the context for that deployed webapp (seen as ${jetty.base}/webapps/<context>.xml)

Example (excluding the DTD which is version specific):

<Configure class="org.eclipse.jetty.webapp.WebAppContext">
  <Set name="contextPath"><Property name="foo"/></Set>
  <Set name="war">/var/web/webapps/foo.war</Set>
  <Set name="tempDirectory">/var/web/work/foo</Set>
</Configure>

The original report of this vulnerability is below:

On Thu, 15 Oct 2020 at 21:14, Jonathan Leitschuh jonathan.leitschuh@gmail.com wrote: Hi WebTide Security Team,

I'm a security researcher writing some custom CodeQL queries to find Local Temporary Directory Hijacking Vulnerabilities. One of my queries flagged an issue in Jetty.

https://lgtm.com/query/5615014766184643449/

I've recently been looking into security vulnerabilities involving the temporary directory because on unix-like systems, the system temporary directory is shared between all users. There exists a race condition between the deletion of the temporary file and the creation of the directory.

java // ensure file will always be unique by appending random digits tmpDir = File.createTempFile(temp, ".dir", parent); // Attacker knows the full path of the file that will be generated // delete the file that was created tmpDir.delete(); // Attacker sees file is deleted and begins a race to create their own directory before Jetty. // and make a directory of the same name // SECURITY VULNERABILITY: Race Condition! - Attacker beats Jetty and now owns this directory tmpDir.mkdirs();

https://github.com/eclipse/jetty.project/blob/1b59672b7f668b8a421690154b98b4b2b03f254b/jetty-webapp/src/main/java/org/eclipse/jetty/webapp/WebInfConfiguration.java#L511-L518

In several cases the parent parameter will not be the system temporary directory. However, there is one case where it will be, as the last fallback.

https://github.com/eclipse/jetty.project/blob/1b59672b7f668b8a421690154b98b4b2b03f254b/jetty-webapp/src/main/java/org/eclipse/jetty/webapp/WebInfConfiguration.java#L467-L468

If any code is ever executed out of this temporary directory, this can lead to a local privilege escalation vulnerability.

Would your team be willing to open a GitHub security advisory to continue the discussion and disclosure there? https://github.com/eclipse/jetty.project/security/advisories

This vulnerability disclosure follows Google's 90-day vulnerability disclosure policy (I'm not an employee of Google, I just like their policy). Full disclosure will occur either at the end of the 90-day deadline or whenever a patch is made widely available, whichever occurs first.

Cheers, Jonathan Leitschuh

One of my queries flagged an issue in Jetty.\n\u003e\n\u003e https://lgtm.com/query/5615014766184643449/\n\u003e\n\u003e I\u0027ve recently been looking into security vulnerabilities involving the temporary directory because on unix-like systems, the system temporary directory is shared between all users.\n\u003e There exists a race condition between the deletion of the temporary file and the creation of the directory.\n\u003e\n\u003e ```java\n\u003e // ensure file will always be unique by appending random digits\n\u003e tmpDir = File.createTempFile(temp, \".dir\", parent); // Attacker knows the full path of the file that will be generated\n\u003e // delete the file that was created\n\u003e tmpDir.delete(); // Attacker sees file is deleted and begins a race to create their own directory before Jetty.\n\u003e // and make a directory of the same name\n\u003e // SECURITY VULNERABILITY: Race Condition! - Attacker beats Jetty and now owns this directory\n\u003e tmpDir.mkdirs();\n\u003e ```\n\u003e\n\u003e https://github.com/eclipse/jetty.project/blob/1b59672b7f668b8a421690154b98b4b2b03f254b/jetty-webapp/src/main/java/org/eclipse/jetty/webapp/WebInfConfiguration.java#L511-L518\n\u003e\n\u003e In several cases the `parent` parameter will not be the system temporary directory. However, there is one case where it will be, as the last fallback.\n\u003e\n\u003e\n\u003e https://github.com/eclipse/jetty.project/blob/1b59672b7f668b8a421690154b98b4b2b03f254b/jetty-webapp/src/main/java/org/eclipse/jetty/webapp/WebInfConfiguration.java#L467-L468\n\u003e\n\u003e If any code is ever executed out of this temporary directory, this can lead to a local privilege\u00a0escalation vulnerability.\n\u003e\n\u003e Would your team be willing to open a GitHub security advisory to continue the discussion and disclosure there?\u00a0https://github.com/eclipse/jetty.project/security/advisories\n\u003e\n\u003e **This vulnerability disclosure follows Google\u0027s [90-day vulnerability disclosure policy](https://www.google.com/about/appsecurity/) (I\u0027m not an employee of Google, I just like their policy). Full disclosure will occur either at the end of the 90-day deadline or whenever a patch is made widely available, whichever occurs first.**\n\u003e\n\u003e Cheers,\n\u003e Jonathan Leitschuh\n\n\n",

Vulnerability from github – Published: 2021-03-11 03:09 – Updated: 2022-10-25 20:35
VLAI
Summary
Generated Code Contains Local Information Disclosure Vulnerability
Details

Impact

This vulnerability impacts generated code. If this code was generated as a one-off occasion, not as a part of an automated CI/CD process, this code will remain vulnerable until fixed manually!

On Unix-Like systems, the system temporary directory is shared between all local users. When files/directories are created, the default umask settings for the process are respected. As a result, by default, most processes/apis will create files/directories with the permissions -rw-r--r-- and drwxr-xr-x respectively, unless an API that explicitly sets safe file permissions is used.

Java Code

The method File.createTempFile from the JDK is vulnerable to this local information disclosure vulnerability.

Patches

Fix has been applied to the master branch with:

  • https://github.com/swagger-api/swagger-codegen/commit/35adbd552d5f99b3ff1e0e59da228becc85190f2

included in release: 2.4.19

Workarounds

Users can remediate the vulnerability in non patched version by manually (or programmatically e.g. in CI) updating the generated source code to use java.nio.files.Files temporary file creation instead of java.io.File, e.g. by changing


    if (tempFolderPath == null)
      return File.createTempFile(prefix, suffix);
    else
      return File.createTempFile(prefix, suffix, new File(tempFolderPath));

to 


    if (tempFolderPath == null)
      return Files.createTempFile(prefix, suffix).toFile();
    else
      return Files.createTempFile(Paths.get(tempFolderPath), prefix, suffix).toFile();

or generally changing:


File.createTempFile(prefix, suffix);

to 


Files.createTempFile(prefix, suffix).toFile();

Original vulnerability report

I'm performing OSS security research under the GitHub Security Lab Bug Bounty program. I've been using a custom CodeQL query to find local temporary directory vulnerabilities in OSS with three custom CodeQL queries.

  • https://github.com/github/codeql/pull/4388/files#diff-71d36c0f2bd0b08e32866f873f1c906cdc17277e0ad327c0c6cd2c882f30de4f
  • https://github.com/github/codeql/pull/4388/files#diff-1893a18a8bf43c011d61a7889d0139b998a5a78701a30fe7722eddd4c506aaac
  • https://github.com/github/codeql/pull/4473

The code generated by the Swagger Generator contains a local information disclosure vulnerability. The system temporary directory, on unix-like systems is shared between multiple users. Information written to this directory, or directories created under this directory that do not correctly set the posix standard permissions can have these directories read/modified by other users.

This code exists in the code generator, in the generated code.

In this case, I believe this is only a local information disclosure. IE. another user can read the information, not replace it.

In particular, the method File.createTempFile from the JDK is vulnerable to this local information disclosure vulnerability.

This is because File.createTempFile creates a file inside of the system temporary directory with the permissions: -rw-r--r--. Thus the contents of this file are viewable by all other users locally on the system.

  • https://github.com/swagger-api/swagger-codegen/blob/068b1ebcb7b04a48ad38f1cadd24bb3810c9f1ab/modules/swagger-codegen/src/main/resources/kotlin-client/infrastructure/ApiClient.kt.mustache#L209
  • https://github.com/swagger-api/swagger-codegen/blob/068b1ebcb7b04a48ad38f1cadd24bb3810c9f1ab/modules/swagger-codegen/src/main/resources/finch/api.mustache#L84
  • https://github.com/swagger-api/swagger-codegen/blob/068b1ebcb7b04a48ad38f1cadd24bb3810c9f1ab/modules/swagger-codegen/src/main/resources/Java/libraries/okhttp-gson/ApiClient.mustache#L831-L834
  • https://github.com/swagger-api/swagger-codegen/blob/068b1ebcb7b04a48ad38f1cadd24bb3810c9f1ab/modules/swagger-codegen/src/main/resources/Java/libraries/jersey2/ApiClient.mustache#L630-L633

The fix here is to switch to the Files API, instead of File as that appropriately sets the file permissions.

As a result, by default, most processes/apis will create files/directories with the permissions `-rw-r--r--` and `drwxr-xr-x` respectively, unless an API that explicitly sets safe file permissions is used.\n\n#### Java Code\n\nThe method `File.createTempFile` from the JDK is vulnerable to this local information disclosure vulnerability.\n\n- https://github.com/swagger-api/swagger-codegen/blob/068b1ebcb7b04a48ad38f1cadd24bb3810c9f1ab/modules/swagger-codegen/src/main/resources/kotlin-client/infrastructure/ApiClient.kt.mustache#L209\n- https://github.com/swagger-api/swagger-codegen/blob/068b1ebcb7b04a48ad38f1cadd24bb3810c9f1ab/modules/swagger-codegen/src/main/resources/finch/api.mustache#L84\n- https://github.com/swagger-api/swagger-codegen/blob/068b1ebcb7b04a48ad38f1cadd24bb3810c9f1ab/modules/swagger-codegen/src/main/resources/Java/libraries/okhttp-gson/ApiClient.mustache#L831-L834\n- https://github.com/swagger-api/swagger-codegen/blob/068b1ebcb7b04a48ad38f1cadd24bb3810c9f1ab/modules/swagger-codegen/src/main/resources/Java/libraries/jersey2/ApiClient.mustache#L630-L633\n\n### Patches\n\nFix has been applied to the master branch with:\n\n* https://github.com/swagger-api/swagger-codegen/commit/35adbd552d5f99b3ff1e0e59da228becc85190f2\n\nincluded in release: 2.4.19\n\n\n### Workarounds\n\nUsers can remediate the vulnerability in non patched version by manually (or programmatically e.g. in CI) updating the generated source code to use `java.nio.files.Files` temporary file creation instead of `java.io.File`, e.g. by changing\n\n```java\n\n    if (tempFolderPath == null)\n      return File.createTempFile(prefix, suffix);\n    else\n      return File.createTempFile(prefix, suffix, new File(tempFolderPath));\n\n```\n\nto \n\n```java\n\n    if (tempFolderPath == null)\n      return Files.createTempFile(prefix, suffix).toFile();\n    else\n      return Files.createTempFile(Paths.get(tempFolderPath), prefix, suffix).toFile();\n\n```\n\nor generally changing:\n\n```java\n\nFile.createTempFile(prefix, suffix);\n\n```\n\nto \n\n```java\n\nFiles.createTempFile(prefix, suffix).toFile();\n\n```\n\n### References\n\n* [CWE-378: Creation of Temporary File With Insecure Permissions](https://cwe.mitre.org/data/definitions/378.html)\n* [CWE-200: Exposure of Sensitive Information to an Unauthorized Actor](https://cwe.mitre.org/data/definitions/200.html)\n* [CWE-732: Incorrect Permission Assignment for Critical Resource](https://cwe.mitre.org/data/definitions/732.html)\n\n### For more information\nIf you have any questions or comments about this advisory:\n\n* Email us at [security@swagger.io](mailto:security@swagger.io)\n\n#### Original vulnerability report\n\n\u003e I\u0027m performing OSS security research under the GitHub Security Lab Bug Bounty program.\n\u003e I\u0027ve been using a custom CodeQL query to find local temporary directory vulnerabilities in OSS with three custom CodeQL queries.\n\u003e \n\u003e - https://github.com/github/codeql/pull/4388/files#diff-71d36c0f2bd0b08e32866f873f1c906cdc17277e0ad327c0c6cd2c882f30de4f\n\u003e - https://github.com/github/codeql/pull/4388/files#diff-1893a18a8bf43c011d61a7889d0139b998a5a78701a30fe7722eddd4c506aaac\n\u003e - https://github.com/github/codeql/pull/4473\n\u003e \n\u003e The code generated by the Swagger Generator contains a local information disclosure vulnerability. The system temporary directory, on unix-like systems is shared between multiple users. Information written to this directory, or directories created under this directory that do not correctly set the posix standard permissions can have these directories read/modified by other users.\n\u003e \n\u003e ---\n\u003e \n\u003e This code exists in the code generator, in the generated code.\n\u003e \n\u003e In this case, I believe this is only a local information disclosure. IE. another user can read the information, not replace it.\n\u003e \n\u003e In particular, the method `File.createTempFile` from the JDK is vulnerable to this local information disclosure vulnerability.\n\u003e \n\u003e This is because `File.createTempFile` creates a file inside of the system temporary directory with the permissions: `-rw-r--r--`. Thus the contents of this file are viewable by all other users locally on the system.\n\u003e \n\u003e - https://github.com/swagger-api/swagger-codegen/blob/068b1ebcb7b04a48ad38f1cadd24bb3810c9f1ab/modules/swagger-codegen/src/main/resources/kotlin-client/infrastructure/ApiClient.kt.mustache#L209\n\u003e - https://github.com/swagger-api/swagger-codegen/blob/068b1ebcb7b04a48ad38f1cadd24bb3810c9f1ab/modules/swagger-codegen/src/main/resources/finch/api.mustache#L84\n\u003e - https://github.com/swagger-api/swagger-codegen/blob/068b1ebcb7b04a48ad38f1cadd24bb3810c9f1ab/modules/swagger-codegen/src/main/resources/Java/libraries/okhttp-gson/ApiClient.mustache#L831-L834\n\u003e - https://github.com/swagger-api/swagger-codegen/blob/068b1ebcb7b04a48ad38f1cadd24bb3810c9f1ab/modules/swagger-codegen/src/main/resources/Java/libraries/jersey2/ApiClient.mustache#L630-L633\n\u003e \n\u003e The fix here is to switch to the `Files` API, instead of `File` as that appropriately sets the file permissions.\n\u003e ",

}
Mitigation
Requirements

Many contemporary languages have functions which properly handle this condition. Older C temp file functions are especially susceptible.

Mitigation
Implementation

Ensure that you use proper file permissions. This can be achieved by using a safe temp file function. Temporary files should be writable and readable only by the process that owns the file.

Mitigation
Implementation

Randomize temporary file names. This can also be achieved by using a safe temp-file function. This will ensure that temporary files will not be created in predictable places.
