CVE-2025-2545: Deprecated 3DES cryptographic algorithm used by Request Tracker in emails encrypted with S/MIME

Noroxi assessment

Priority: Monitor (action score 9/100)

  • 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: 0.19% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. Special conditions such as timing or configuration are required.
  • Fixed version: request-tracker4 (Debian:11) 4.4.4+dfsg-2+deb11u4; request-tracker4 (Debian:12) 4.4.6+dfsg-1.1+deb12u2; request-tracker5 (Debian:12) 5.0.3+dfsg-3~deb12u3.

Low priority for now. Upgrade to request-tracker4 (Debian:11) 4.4.4+dfsg-2+deb11u4; request-tracker4 (Debian:12) 4.4.6+dfsg-1.1+deb12u2; request-tracker5 (Debian:12) 5.0.3+dfsg-3~deb12u3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Vulnerability in Best Practical Solutions, LLC's Request Tracker prior to v5.0.8, where the Triple DES (3DES) cryptographic algorithm is used to protect emails sent with S/MIME encryption. Triple DES is considered obsolete and insecure due to its susceptibility to birthday attacks, which could compromise the confidentiality of encrypted messages.
