CVE-2023-22960: Lexmark products through 2023-01-10 have Improper Control of Interaction Frequency.

Noroxi assessment

Priority: Monitor (action score 38/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 27.9% (FIRST EPSS); higher than 98.1% 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.
  • 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.
