CVE-2023-47211: A directory traversal vulnerability exists in the uploadMib functionality of ManageEngine OpManager 12.7.258.

Noroxi assessment

Priority: Plan (action score 48/100)

A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
Public proof-of-concept code exists (Exploit-DB / GitHub); there is no record of exploitation in the wild.
Probability of exploitation in the next 30 days: 47% (FIRST EPSS); higher than 98.8% 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 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.

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.

Fixed

1const file = path.resolve(ROOT, req.query.name);
