Vulnerability from csaf_siemens - Published: 2026-07-09 00:00 - Updated: 2026-07-09 00:00
Summary
SSA-229470: Multiple Vulnerabilities in SICAM 8 Products Before V26.20
Notes
Summary: Multiple SICAM 8 products are affected by multiple vulnerabilities that could lead to denial of service, namely: - SICAM A8000 Device firmware - CPCI85 for CP-8031/CP-8050 - SICORE for CP-8010/CP-8012 - SICAM EGS Device firmware - CPCI85 - SICAM S8000 - SICORE Siemens has released new versions for the affected products and recommends to update to the latest versions.
General Recommendations: Operators of critical power systems (e.g. TSOs or DSOs) worldwide are usually required by regulations to build resilience into the power grids by applying multi-level redundant secondary protection schemes. It is therefore recommended that the operators check whether appropriate resilient protection measures are in place. The risk of cyber incidents impacting the grid's reliability can thus be minimized by virtue of the grid design. Siemens strongly recommends applying the provided security updates using the corresponding tooling and documented procedures made available with the product. If supported by the product, an automated means to apply the security updates across multiple product instances may be used. Siemens strongly recommends prior validation of any security update before being applied, and supervision by trained staff of the update process in the target environment. As a general security measure Siemens strongly recommends to protect network access with appropriate mechanisms (e.g. firewalls, segmentation, VPN). It is advised to configure the environment according to our operational guidelines in order to run the devices in a protected IT environment. Recommended security guidelines can be found at: https://www.siemens.com/gridsecurity

CVE-2026-54798

The affected application includes a debugging interface that is accessible through HTTP endpoints. This could allow an authenticated attacker to disrupt the system by crashing the web process causing denial of service conditions.

6.5 (Medium)
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
CWE-489 - Active Debug Code
Affected products

Vendor Fix
SICORE Base system < V26.20.0
Siemens / SICORE Base system
 vers:intdot/<26.20.0
Vendor Fix
CVE-2026-54799

The affected application contains a vulnerability in its firmware update mechanism's signature validation process. This could allow an attacker to install malicious firmware, leading to persistent code execution and system compromise.

6.7 (Medium)
CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

Vendor Fix
CVE-2026-54800

The affected application ships with a default configuration that disables all OPC UA security mechanisms. This could allow an attacker to gain unauthorized access and control over critical system functions.

4.8 (Medium)
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N
