Siemens SIMATIC S7-1500 CPUs Authentication Bypass Using an Alternate Path or Channel (CVE-2024-46887)
medium Tenable OT Security Plugin ID 502652
Synopsis
The remote OT asset is affected by a vulnerability.Description
The web server of affected devices do not properly authenticate user request to the '/ClientArea/RuntimeInfoData.mwsl' endpoint. This could allow an unauthenticated remote attacker to gain knowledge about current actual and configured maximum cycle times as well as about configured maximum communication load.This plugin only works with Tenable.ot.
