ImageMagick - Information Disclosure via AES-CTR Nonce Reuse in PasskeyEncipherImage

Noroxi assessment

Priority: Monitor (action score 25/100)

  • 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: 0.23% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: ImageMagick ImageMagick 6.9.13-47, 7.1.2-22.

Low priority for now. Upgrade to ImageMagick ImageMagick 6.9.13-47, 7.1.2-22 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

ImageMagick before 7.1.2-22 contains an information disclosure vulnerability in the PasskeyEncipherImage method due to AES-CTR nonce reuse. Attackers can exploit nonce reuse in the cipher implementation to recover plaintext information from encrypted images.
