MediumCVSS 6.5 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 27/100)

  • 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: 3.6% (FIRST EPSS); higher than 89.7% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: postgresql-8.4 (Debian:6.0) 8.4.11-0squeeze1; postgresql93 (openSUSE:Tumbleweed) 9.3.15-1.1; postgresql94 (openSUSE:Tumbleweed) 9.4.10-1.1.

Low priority for now. Upgrade to postgresql-8.4 (Debian:6.0) 8.4.11-0squeeze1; postgresql93 (openSUSE:Tumbleweed) 9.3.15-1.1; postgresql94 (openSUSE:Tumbleweed) 9.4.10-1.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

CREATE TRIGGER in PostgreSQL 8.3.x before 8.3.18, 8.4.x before 8.4.11, 9.0.x before 9.0.7, and 9.1.x before 9.1.3 does not properly check the execute permission for trigger functions marked SECURITY DEFINER, which allows remote authenticated users to execute otherwise restricted triggers on arbitrary data by installing the trigger on an attacker-owned table.
