CVE-2026-25573 is a high-severity External Control of File Name or Path (CWE-73) vulnerability in Siemens Sicam Siapp Sdk. Its CVSS base score is 8.6 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 32th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-25573 is a command injection vulnerability (CWE-73) in the SICAM SIAPP SDK, affecting all versions prior to V2.1.7. The flaw arises because the application constructs shell commands using caller-provided strings and then executes them, enabling an attacker to manipulate the command structure. This can lead to arbitrary command execution and potential full system compromise. The vulnerability carries a CVSS v3.1 base score of 7.4 (AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).
A local attacker can exploit this vulnerability without requiring privileges or user interaction, though the attack demands high complexity. By supplying malicious input that influences the shell command construction, the attacker can inject and execute arbitrary commands, achieving high-impact confidentiality, integrity, and availability effects, up to full system compromise.
Siemens Security Advisory SSA-903736, available at https://cert-portal.siemens.com/productcert/html/ssa-903736.html, details mitigation steps, recommending an update to SICAM SIAPP SDK V2.1.7 or later to address the vulnerability.

Mitigating Controls (NIST 800-53 r5) AI
Input validation directly rejects or sanitizes untrusted path strings before they reach filesystem operations.
Enforces authorization checks on the actual resource accessed, blocking unauthorized files even when a malicious path is supplied.
Least-privilege limits the set of files or directories any subject can affect, shrinking the blast radius of a path-control flaw.

Security testing can detect path-traversal issues but does not itself implement preventive controls.
Secure development lifecycle mandates input validation and path-handling controls that directly prevent external file/path manipulation.
Application security requirements explicitly call for controls against untrusted input influencing file operations.
Secure architecture principles discourage unsafe path construction but do not prescribe concrete file-name controls.
Secure coding standards require canonicalization, allow-listing, and bounds checks on file paths, directly eliminating CWE-73.
Information access restriction limits which files can be reached, indirectly reducing impact of path manipulation.
