An XML external entity or XXE vulnerability in the SAML component of Ivanti Connect Secure (9.x, 22.x), Ivanti Policy Secure (9.x, 22.x) and ZTA gateways which allows an attacker to access certain restricted resources without authentication.

A non-destructive PoC has been released. Because of past targeting of Ivanti Connect and Policy Secure devices, we advise upgrading as soon as possible.

Because of recent, persistent targeting of Ivanti Connect and Policy Secure by attackers, we encourage customers to upgrade as soon as possible.

Ivanti Connect Secure 9.x, 22.x suffers from an XML External Entity.

By crafting a specific HTTP request, a remote attacker could exploit this vulnerability to access certain restricted resources without authentication.

The Ivanti Policy Secure installed on the remote host is 9.x or 22.x. It is, therefore, affected by multiple vulnerabilities:

  - An authentication bypass vulnerability in the web component of Ivanti Policy Secure (9.x, 22.x) and Ivanti Policy     Secure allows a remote attacker to access restricted resources by bypassing control checks. (CVE-2023-46805)

  - A command injection vulnerability in web components of Ivanti Policy Secure (9.x, 22.x) and Ivanti Policy Secure     allows an authenticated administrator to send specially crafted requests and execute arbitrary commands on the     appliance. This vulnerability can be exploited over the internet. (CVE-2024-21887)

  - A privilege escalation vulnerability in web component of Ivanti Policy Secure (9.x, 22.x) and Ivanti Policy Secure     (9.x, 22.x) allows a user to elevate privileges to that of an administrator. (CVE-2024-21888)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
