sudo-rs is a memory safe implementation of sudo and su written in Rust. Prior to version 0.2.6, users with no (or very limited) sudo privileges can determine whether files exists in folders that they otherwise cannot access using `sudo --list <pathname>`. Users with local access to a machine can discover the existence/non-existence of certain files, revealing potentially sensitive information in the file names. This information can also be used in conjunction with other attacks. Version 0.2.6 fixes the vulnerability.

GHSA-98cv-wqjx-wx8f — sudo-rs Allows Low Privilege Users to Discover the Existence of Files in Inaccessible Folders

Affected: crates.io: sudo-rs

### Summary

Users with no (or very limited) sudo privileges can determine whether files exists in folders that they otherwise cannot access using `sudo --list <pathname>`.

### PoC

As root: ``` # mkdir /tmp/foo # chmod a-rwx /tmp/foo # touch /tmp/foo/secret_file ``` As a user without any (or limited) sudo rights: ``` $ sudo --list /tmp/foo/nonexistent_file sudo-rs: '/tmp/foo/nonexistent_file': command not found $ $ sudo --list /tmp/foo/secret_file sudo-rs: Sorry, user eve may not run sudo on host. ``` I.e. the user can distinguish whether files exist.

### Related Original sudo (vulnerable version tested by us: 1.9.15p5) exhibited similar behaviour for files with the executable bit set.

### Impact Users with local access to a machine can discover the existence/non-existence of certain files, revealing potentially sensitive information in the file names. This information can also be used in conjunction with other attacks.
