CVE-2024-6782: Calibre Remote Code Execution

Noroxi assessment

Priority: This week (action score 64/100)

  • A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 84.1% (FIRST EPSS); higher than 99.6% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: calibre (Debian:12) 6.13.0+repack-2+deb12u4; calibre (Debian:13) 7.16.0+ds-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Upgrade to calibre (Debian:12) 6.13.0+repack-2+deb12u4; calibre (Debian:13) 7.16.0+ds-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Improper access control in Calibre 6.9.0 ~ 7.14.0 allow unauthenticated attackers to achieve remote code execution.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
