Noroxi assessment

Priority: Plan (action score 42/100)

  • 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: 5.9% (FIRST EPSS); higher than 93.3% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: cyrus-imapd (Debian:12) 1.5.19-20; cyrus21-imapd (Debian:3.0) 1.5.19-9.2.

Add it to your regular patch cycle. Upgrade to cyrus-imapd (Debian:12) 1.5.19-20; cyrus21-imapd (Debian:3.0) 1.5.19-9.2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The argument parser of the PARTIAL command in Cyrus IMAP Server 2.2.6 and earlier allows remote authenticated users to execute arbitrary code via a certain command ("body[p") that is treated as a different command ("body.peek") and causes an index increment error that leads to an out-of-bounds memory corruption.
