Siemens SIPROTEC 5 Compact 7SX800 Session Identifier random values

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

It has been rated as problematic. Affected by this issue is an unknown function of the component Session Identifier Handler. The manipulation with an unknown input leads to a random values vulnerability. Using CWE to declare the problem leads to CWE-334. The number of possible random values is smaller than needed by the product, making it more susceptible to brute force attacks. Impacted is confidentiality. CVE summarizes:

A vulnerability has been identified in SIPROTEC 5 6MD84 (CP300) (All versions = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80), SIPROTEC 5 7SA82 (CP150) (All versions = V7.80 = V7.80 = V7.80), SIPROTEC 5 7SD82 (CP150) (All versions = V7.80 = V7.80 = V7.80), SIPROTEC 5 7SJ81 (CP150) (All versions = V7.80), SIPROTEC 5 7SJ82 (CP150) (All versions = V7.80 = V7.80 = V7.80), SIPROTEC 5 7SK82 (CP150) (All versions = V7.80 = V7.80), SIPROTEC 5 7SL82 (CP150) (All versions = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 = V7.80), SIPROTEC 5 7UT82 (CP150) (All versions = V7.80 = V7.80 = V7.80 = V7.80 = V7.80 < V11.0), SIPROTEC 5 7VU85 (CP300) (All versions < V11.0), SIPROTEC 5 Compact 7SX800 (CP050) (All versions < V11.0). Affected devices do not use sufficiently random values to create session identifiers. This could allow an unauthenticated remote attacker to brute force a session identifier and gain read access to limited information from the web server without authorization.

The advisory is available at cert-portal.siemens.com. This vulnerability is handled as CVE-2024-54017 since 11/27/2024. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 05/12/2026). This vulnerability is assigned to T1600.001 by the MITRE ATT&CK project.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at CERT Bund (WID-SEC-2026-1473). If you want to get best quality of vulnerability data, you may have to visit VulDB.
