CVE-2022-33757Network attack vector

Information disclosure via unchecked debug-log attachment access

Published Oct 24, 2022 · Updated May 7, 2025

Improper access control in Tenable Nessus 10.1.2 and earlier allows remote authenticated users to read debug-log attachments. The web UI serves Nessus Debug Log file attachments without enforcing the requester's privileges, exposing scan and target details. A valid account and network access to the Nessus instance are required, and the reported impact is limited to confidentiality.
