sudo-rs: Partial password reveal is possible after timeout

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

sudo-rs is a memory safe implementation of sudo and su written in Rust. Starting in version 0.2.7 and prior to version 0.2.10, 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. 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. Version 0.2.10 fixes the issue.

### 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.
