Siemens SIMATIC S7-1500 and S7-1200 CPUs URL Redirection to Untrusted Site (CVE-2024-46886)

medium Tenable OT Security Plugin ID 502651

Synopsis

The remote OT asset is affected by a vulnerability.

Description

The web server of affected devices does not properly validate input that is used for a user redirection. This could allow an attacker to make the server redirect the legitimate user to an attacker-chosen URL. For a successful exploit, the legitimate user must actively click on an attacker-crafted link.

This plugin only works with Tenable.ot.
