CVE-2020-11858: Code execution with escalated privilegesn vlnerability in Operation bridge Manager and Operations Bridge (containerized) products.

Noroxi assessment

Priority: Plan (action score 40/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Because a ready-made attack tool exists, priority is at least “Plan”.
  • Probability of exploitation in the next 30 days: 2.6% (FIRST EPSS); higher than 85.8% of all records.
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. 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.
