CVE-2023-26261Network attack vector

Authentication bypass via blind XPath session theft

Published Mar 8, 2023 · Updated Mar 5, 2025

Blind XPath injection in UBIKA WAAP Gateway/Cloud 6.10 and earlier allows remote attackers to steal an active user's session. The public record does not identify the affected request field or explain how untrusted input enters the XPath expression. The administration interface listens on TCP port 3001, and exploitation requires another connected user whose session can be stolen.
