Stack-based buffer overflow in Siemens SICAM SIAPP SDK server component

IdentifiersCVE-2026-25572CWE-121

CVE-2026-25572 affects Siemens SICAM SIAPP SDK server component in all versions prior to V2.1.7. According to the provided content, the server component does not enforce maximum length checks on certain variables before they are used. An attacker can supply oversized input to these variables, which may trigger a stack overflow. The documented consequence is a crash of the affected process, with potential denial-of-service impact.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can crash the SICAM SIAPP SDK server component process, resulting in denial of service. Because the issue is described as a stack overflow caused by oversized input, memory corruption occurs on the stack; however, the provided information only explicitly confirms process crash and potential DoS, not reliable code execution.

Mitigation

If you can’t patch tonight, do this now.

If immediate upgrade is not possible, reduce exposure of the SICAM SIAPP SDK server component by restricting network access to trusted hosts and limiting the ability of untrusted parties to send input to the affected service. Apply vendor-recommended workarounds from the relevant Siemens advisories until the product can be updated. Specific mitigations beyond patching are not provided in the supplied content.

Remediation

Patch, then assume compromise.

Upgrade Siemens SICAM SIAPP SDK to V2.1.7 or later. The provided content states that all versions earlier than V2.1.7 are affected and references Siemens security bulletins published on 10 March 2026 for fixes.
