Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-25195 is an OS command injection vulnerability (CWE-78) affecting XWEB Pro version 1.12.1 and prior versions. It allows an authenticated attacker to achieve remote code execution on the affected system by supplying a crafted firmware update file through the firmware update route. The vulnerability has 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 privileges, changed scope, and high impact on confidentiality, integrity, and availability.
An authenticated attacker with high privileges can exploit this vulnerability remotely by crafting a malicious firmware update file and submitting it via the designated firmware update endpoint. Successful exploitation leads to arbitrary OS command execution on the target system, potentially enabling full compromise, data exfiltration, persistence, or further lateral movement within the environment.
Mitigation details are outlined in CISA ICS Advisory ICSA-26-057-10, available at https://www.cisa.gov/news-events/ics-advisories/icsa-26-057-10, along with the corresponding CSAF file at https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-057-10.json. Additional guidance on system software updates is provided by Copeland 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).
