CriticalCVSS 10.0 · v2.0—Proof of concept No fix recorded

Noroxi assessment

Priority: Plan (action score 52/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 40% (FIRST EPSS); higher than 98.6% of all records.
  • No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

Integer signedness error in the authentication functionality in librpc.dll in the Informix Storage Manager (ISM) Portmapper service (aka portmap.exe), as used in IBM Informix Dynamic Server (IDS) 10.x before 10.00.TC9 and 11.x before 11.10.TC3 and EMC Legato NetWorker, allows remote attackers to execute arbitrary code via a crafted parameter size that triggers a stack-based buffer overflow.
