CVE-2022-23614: Code injection in Twig

Noroxi assessment

Priority: Plan (action score 41/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 8.2% (FIRST EPSS); higher than 94.8% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: php-twig (Debian:11) 2.14.3-1+deb11u1; php-twig (Debian:12) 3.3.8-1; twig/twig (Packagist) 2.14.11, 3.3.8.

Add it to your regular patch cycle. Upgrade to php-twig (Debian:11) 2.14.3-1+deb11u1; php-twig (Debian:12) 3.3.8-1; twig/twig (Packagist) 2.14.11, 3.3.8 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

Twig is an open source template language for PHP. When in a sandbox mode, the `arrow` parameter of the `sort` filter must be a closure to avoid attackers being able to run arbitrary PHP functions. In affected versions this constraint was not properly enforced and could lead to code injection of arbitrary PHP code. Patched versions now disallow calling non Closure in the `sort` filter as is the case for some other filters. Users are advised to upgrade.
