CVE-2026-25109 is an OS command injection vulnerability (CWE-78) in XWEB Pro version 1.12.1 and prior. Published on 2026-02-27, it enables an authenticated attacker to achieve remote code execution on the affected system by injecting malicious input into the devices field when accessing the get setup route. The vulnerability carries a CVSS v3.1 base score of 8.0 (AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H), indicating high severity with network accessibility, high attack complexity, required high privileges, no user interaction, changed scope, and high impacts across confidentiality, integrity, and availability.
An authenticated attacker with high-level privileges can exploit this vulnerability remotely over the network. By crafting malicious input for the devices field during access to the get setup route, the attacker triggers OS command injection, resulting in arbitrary remote code execution on the system.
Mitigation guidance is available in related advisories, including CISA ICSA-26-057-10 at https://www.cisa.gov/news-events/ics-advisories/icsa-26-057-10, the corresponding CSAF file at https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-057-10.json, and the vendor's system software update page at https://webapps.copeland.com/Dixell/Pages/SystemSoftwareUpdate.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
