Noroxi assessment

Priority: This week (action score 61/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 69.6% (FIRST EPSS); higher than 99.3% of all records.
  • No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

Multiple stack-based buffer overflows in HP OpenView Network Node Manager (OV NNM) 6.41, 7.01, and 7.51 allow remote attackers to execute arbitrary code via unspecified long arguments to (1) ovlogin.exe, (2) OpenView5.exe, (3) snmpviewer.exe, and (4) webappmon.exe, as demonstrated via a long Action parameter to OpenView5.exe.
