Noroxi assessment

Priority: Monitor (action score 39/100)

  • 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: 6.8% (FIRST EPSS); higher than 94% of all records.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

Sophos Web Appliance before 3.7.8.2 allows (1) remote attackers to execute arbitrary commands via shell metacharacters in the client-ip parameter to the Block page, when using the user_workstation variable in a customized template, and remote authenticated users to execute arbitrary commands via shell metacharacters in the (2) url parameter to the Diagnostic Tools functionality or (3) entries parameter to the Local Site List functionality.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
