How to Fix CVE-2025-64170

To remediate this vulnerability, upgrade all affected sudo-rs dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

sudo-rs fixed: 0.2.10 
Upgrade sudo-rs to 0.2.10
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for sudo-rs

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-64170, inspect your project dependencies for sudo-rs:

inspect dependencies for sudo-rs

Analyze the terminal output to locate any version of sudo-rs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.2.10), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-549: Missing Password Field Masking, where the product does not mask passwords during entry, increasing the potential for attackers to observe and capture passwords. In sudo-rs, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary If a user begins entering a password but does not press return for an extended period, a password timeout may occur. When this happens, the keystrokes that were entered are echoed back to the console. ### Example Using sudo-rs: ``` geiger@cerberus:~$ sudo -s [sudo: authenticate] Password: sudo-rs: timed out geiger@cerberus:~$ testtesttest ``` "testtesttest" was entered at the password prompt but not confirmed by pressing return and then waiting for the timeout. ### Impact This could reveal partial password information, possibly exposing history files when not carefully handled by the user and on screen, usable for Social Engineering or Pass-By attacks. ### Versions affected Passwords timeouts were added in sudo-rs 0.2.7 (with a default set to 5 minutes). ### Credits This issue was discovered and reported by @DevLaTron.
