CVE-2023-50094: reNgine before 2.1.2 allows OS Command Injection if an adversary has a valid session ID.

HighCVSS 8.8 · v3.1—Proof of concept No fix recorded

Noroxi assessment

Priority: Monitor (action score 39/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 13.5% (FIRST EPSS); higher than 96.5% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • No fixed version is recorded, but the references include a patch (commit or PR) link.

Low priority for now. See the fix and affected versions sections below.

Primary sources: NVD · CVE.org · FIRST EPSS

reNgine before 2.1.2 allows OS Command Injection if an adversary has a valid session ID. The attack places shell metacharacters in an api/tools/waf_detector/?url= string. The commands are executed as root via subprocess.check_output.
