MediumCVSS 5.0 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 21/100)

  • 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: 3.3% (FIRST EPSS); higher than 88.9% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: openssh (Debian:12) 1:3.8p1; openssh (Red Hat:enterprise_linux:3::as) 0:3.6.1p2-33.30.6; openssh-askpass (Red Hat:enterprise_linux:3::as) 0:3.6.1p2-33.30.6.

Low priority for now. Upgrade to openssh (Debian:12) 1:3.8p1; openssh (Red Hat:enterprise_linux:3::as) 0:3.6.1p2-33.30.6; openssh-askpass (Red Hat:enterprise_linux:3::as) 0:3.6.1p2-33.30.6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

sshd.c in OpenSSH 3.6.1p2 and 3.7.1p2 and possibly other versions, when using privilege separation, does not properly signal the non-privileged process when a session has been terminated after exceeding the LoginGraceTime setting, which leaves the connection open and allows remote attackers to cause a denial of service (connection consumption).
