HighCVSS 7.5 · v2.0—Weaponized Fix available

Noroxi assessment

Priority: Plan (action score 49/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • 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: 63.7% (FIRST EPSS); higher than 99.2% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: perl (Debian:12) 5.14.2-16; perl (Red Hat:enterprise_linux:5::server) 4:5.8.8-40.el5_9; perl-debuginfo (Red Hat:enterprise_linux:5::server) 4:5.8.8-40.el5_9.

Add it to your regular patch cycle. Upgrade to perl (Debian:12) 5.14.2-16; perl (Red Hat:enterprise_linux:5::server) 4:5.8.8-40.el5_9; perl-debuginfo (Red Hat:enterprise_linux:5::server) 4:5.8.8-40.el5_9 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The _compile function in Maketext.pm in the Locale::Maketext implementation in Perl before 5.17.7 does not properly handle backslashes and fully qualified method names during compilation of bracket notation, which allows context-dependent attackers to execute arbitrary commands via crafted input to an application that accepts translation strings from users, as demonstrated by the TWiki application before 5.1.3, and the Foswiki application 1.0.x through 1.0.10 and 1.1.x through 1.1.6.
