Noroxi assessment

Priority: Monitor (action score 14/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 2.2% (FIRST EPSS); higher than 82.5% of all records.
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: util-linux (Alpine:v3.20) 2.40-r0; util-linux (Debian:10) 2.33.1-0.1+deb10u1; util-linux (Debian:11) 2.36.1-8+deb11u2.

Low priority for now. Upgrade to util-linux (Alpine:v3.20) 2.40-r0; util-linux (Debian:10) 2.33.1-0.1+deb10u1; util-linux (Debian:11) 2.36.1-8+deb11u2 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
