CVE-2026-25109 is a high-severity OS Command Injection (CWE-78) vulnerability in Copeland Xweb 500B Pro Firmware. Its CVSS base score is 8.0 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 28.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
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.
