CVE-2024-28085: n/a
wall in util-linux through 2.40, often installed with setgid tty permissions, allows escape sequences to be sent to other users' terminals through argv. (Specifically, escape sequences received from stdin are blocked, but escape sequences received from argv are not blocked.) There may be plausible scenarios where this leads to account takeover.
AI Analysis
Technical Summary
CVE-2024-28085 describes a vulnerability in the 'wall' command of util-linux versions up to and including 2.40. The issue arises because while escape sequences received from standard input are blocked, those passed through command-line arguments are not filtered. Since 'wall' is often installed with setgid tty permissions, this can allow an attacker to send escape sequences to other users' terminals. Although the vulnerability has a low CVSS score (3.3) and no confidentiality or availability impact, there is a potential for limited integrity impact, including plausible scenarios of account takeover. No known exploits are reported in the wild, and no patch or vendor advisory is currently available.
Potential Impact
The vulnerability allows an attacker with local privileges to send unfiltered escape sequences to other users' terminals via the 'wall' command's argv input. This could lead to limited integrity impact, such as manipulation of terminal behavior or potential account takeover in certain scenarios. There is no impact on confidentiality or availability. The overall severity is low.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict local user access to the 'wall' utility or remove setgid tty permissions if feasible to reduce risk. Monitor for vendor updates regarding an official fix.
