HighCVSS 7.8 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.46% (FIRST EPSS).
  • 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: ansible (Debian:12) 2.0.1.0-2; ansible (openSUSE:Tumbleweed) 2.2.0.0-1.1; ansible-10 (openSUSE:Tumbleweed) 10.6.0-1.1.

Low priority for now. Upgrade to ansible (Debian:12) 2.0.1.0-2; ansible (openSUSE:Tumbleweed) 2.2.0.0-1.1; ansible-10 (openSUSE:Tumbleweed) 10.6.0-1.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The create_script function in the lxc_container module in Ansible before 1.9.6-1 and 2.x before 2.0.2.0 allows local users to write to arbitrary files or gain privileges via a symlink attack on (1) /opt/.lxc-attach-script, (2) the archived container in the archive_path directory, or the (3) lxc-attach-script.log or (4) lxc-attach-script.err files in the temporary directory.
