Security Summary

CVE-2026-25721 is an OS command injection vulnerability (CWE-78) in XWEB Pro version 1.12.1 and prior. The flaw resides in the API V1 route's restore action, where malicious input can be injected into the server username and/or password fields, published on 2026-02-27 with 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).

An authenticated attacker with high privileges (PR:H) can exploit this vulnerability over the network (AV:N), though it requires high attack complexity (AC:H) and no user interaction (UI:N). Successful exploitation enables remote code execution (RCE) on the affected system, resulting in high impacts to confidentiality, integrity, and availability, with a changed scope (S:C).

Mitigation guidance is available in CISA ICS Advisory ICSA-26-057-10, the associated CSAF document 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.

MITRE ATT&CK Enterprise Techniques

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059 Command and Scripting Interpreter Execution
Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.
Why these techniques?

OS command injection in web API restore action enables exploitation of public-facing application (T1190) for remote code execution via command and scripting interpreter (T1059).
