Noroxi assessment

Priority: Plan (action score 44/100)

  • 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: 14.2% (FIRST EPSS); higher than 96.6% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: lpr (Debian:12) 1:0.48-1.

Add it to your regular patch cycle. Upgrade to lpr (Debian:12) 1:0.48-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The line printer daemon (lpd) in the lpr package in multiple Linux operating systems allows local users to gain root privileges by causing sendmail to execute with arbitrary command line arguments, as demonstrated using the -C option to specify a configuration file.
