CVE-2024-27766: An issue in MariaDB v.11.1 allows a remote attacker to execute arbitrary code via the lib_mysqludf_sys.so function.

Noroxi assessment

Priority: Monitor (action score 22/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.2% (FIRST EPSS); higher than 69.8% of all records.
  • Physical access to the device is required. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

An issue in MariaDB v.11.1 allows a remote attacker to execute arbitrary code via the lib_mysqludf_sys.so function. NOTE: this is disputed by the MariaDB Foundation because no privilege boundary is crossed.
