Noroxi assessment

Priority: Monitor (action score 23/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 8.6% (FIRST EPSS); higher than 95.1% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: php5 (Debian:6.0) 5.3.3-7+squeeze8.

Low priority for now. Upgrade to php5 (Debian:6.0) 5.3.3-7+squeeze8 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

The PDORow implementation in PHP before 5.3.9 does not properly interact with the session feature, which allows remote attackers to cause a denial of service (application crash) via a crafted application that uses a PDO driver for a fetch and then calls the session_start function, as demonstrated by a crash of the Apache HTTP Server.
