Synopsis

Ivanti Connect Secure < 22.8R2.5 / 25.1.1.x < 25.1.1.2 / 25.1.2.x < 25.1.3.1 Authentication Bypass

Description

The Ivanti Connect Secure instance is affected by an authentication bypass caused by inconsistent routing between the web front end and internal CGI dispatcher. Authorization is evaluated using the request URL, while the X-DSCGI-PATH header controls the CGI handler that is executed. A remote, unauthenticated attacker can exploit this discrepancy to access protected CGI handlers, including the wu.cgi file upload functionality, through a publicly accessible welcome.cgi endpoint.

Solution

Upgrade to Ivanti Connect Secure version 22.8R2.5, 25.1.1.2, 25.1.3.1 or later.
