CVE-2025-64170 | sudo-rs: Partial password reveal is possible after timeout

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.

3.8 3.1 LOW
CVSS:3.1/AV:P/AC:H/PR:H/UI:R/S:U/C:H/I:N/A:N Click to expand
Attack vector (AV:P)
Hands-on access—USB, keyboard, opening the case—not something you do purely over the wire.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:H)
They need powerful rights—admin, root, or similar—before this pays off.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
