Bouncy Castle For Java before 1.74 is affected by an LDAP injection vulnerability. The vulnerability only affects applications that use an LDAP CertStore from Bouncy Castle to validate X.509 certificates. During the certificate validation process, Bouncy Castle inserts the certificate's Subject Name into an LDAP search filter without any escaping, which leads to an LDAP injection vulnerability.

GHSA-hr8g-6v94-x4m9 — Bouncy Castle For Java LDAP injection vulnerability

Affected: Maven: org.bouncycastle:bcprov-jdk18on, Maven: org.bouncycastle:bcprov-jdk15to18, Maven: org.bouncycastle:bcprov-jdk14, Maven: org.bouncycastle:bcprov-ext-jdk14, Maven: org.bouncycastle:bcprov-ext-jdk15to18, Maven: org.bouncycastle:bcprov-ext-jdk18on, Maven: org.bouncycastle:bcprov-debug-jdk14, Maven: org.bouncycastle:bcprov-debug-jdk15to18, Maven: org.bouncycastle:bcprov-debug-jdk18on, Maven: org.bouncycastle:bcprov-jdk15on and 2 more

Bouncy Castle provides the `X509LDAPCertStoreSpi.java` class which can be used in conjunction with the CertPath API for validating certificate paths. Pre-1.73 the implementation did not check the X.500 name of any certificate, subject, or issuer being passed in for LDAP wild cards, meaning the presence of a wild car may lead to Information Disclosure.

A potential attack would be to generate a self-signed certificate with a subject name that contains special characters, e.g: `CN=Subject*)(objectclass=`. This will be included into the filter and provides the attacker ability to specify additional attributes in the search query. This can be exploited as a blind LDAP injection: an attacker can enumerate valid attribute values using the boolean blind injection technique. The exploitation depends on the structure of the target LDAP directory, as well as what kind of errors are exposed to the user.

Changes to the `X509LDAPCertStoreSpi.java` class add the additional checking of any X.500 name used to correctly escape wild card characters.

OESA-2023-1391 — bouncycastle security update

Affected: openEuler:20.03-LTS-SP1: bouncycastle, openEuler:20.03-LTS-SP3: bouncycastle, openEuler:22.03-LTS: bouncycastle, openEuler:22.03-LTS-SP1: bouncycastle

A Java implementation of cryptographic algorithms. Security Fix(es): A flaw was found in Bouncy Castle 1.73. This issue targets the fix of LDAP wild cards. Before the fix there was no validation for the X.500 name of any certificate, subject, or issuer, so the presence of a wild card may lead to information disclosure. This could allow a malicious user to obtain unauthorized information via blind LDAP Injection, exploring the environment and enumerating data. The exploit depends on the structure of the target LDAP directory as well as what kind of errors are exposed to the user.(CVE-2023-33201)
