CVE-2024-41796 Siemens CVE debrief

Who should care

OT/ICS operators, Siemens SENTRON 7KT PAC1260 Data Manager administrators, and defenders responsible for the device’s web management interface should care most. The risk is highest for teams that rely on browser-based admin sessions and cannot tightly control user interaction during management tasks.

Technical summary

The advisory states that the affected device web interface allows the login password to be changed without knowing the current password. In combination with a prepared CSRF attack (CVE-2024-41795), this can let an unauthenticated attacker force a password change to a value they control. Siemens/CISA assign CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N, reflecting network reachability, required user interaction, and high integrity impact with no confidentiality or availability impact indicated.

Defensive priority

Medium. Treat as higher urgency if administrators use the web interface from general browsing sessions or if the management surface is difficult to isolate, because successful chaining can lead to account takeover through password replacement.

Recommended defensive actions

• Follow the Siemens/CISA advisory guidance for this product and monitor for any later vendor update, noting that the source advisory currently says no fix is planned.
• Do not access links from untrusted sources while logged in to affected devices; log out of the management interface before browsing external content.
• Restrict access to the device web interface to trusted administrative workflows and apply general ICS defensive practices referenced by CISA.
• Review administrative accounts and credentials for unexpected password changes, and investigate any suspicious login or configuration activity.
• Track CVE-2024-41795 as a prerequisite part of the attack chain, since the password-change issue is described as dangerous in combination with that CSRF flaw.

Evidence notes

The supplied CISA CSAF source (ICSA-25-100-06) and Siemens references identify Siemens SENTRON 7KT PAC1260 Data Manager as the affected product and repeat the same vulnerability description. The advisory was published and modified on 2025-04-08. The remediation section in the source says no fix is currently planned and explicitly advises not to access links from untrusted sources while logged in at affected devices.
