CVE-2026-25196 is a high-severity OS Command Injection (CWE-78) vulnerability in Copeland Xweb 300D 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 at the 13.3th percentile by exploit likelihood (below the median); 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).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly prevents OS command injection by validating the correctness and context of inputs to Wi-Fi SSID and password fields before processing.
Remediates the specific command injection flaw in XWEB Pro through timely flaw remediation and application of vendor-provided software updates.
Enforces restrictions on harmful input types, such as shell metacharacters, in Wi-Fi configuration fields to block command injection attempts.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The vulnerability is an OS command injection (CWE-78) in a web interface (XWEB Pro), enabling authenticated remote code execution, directly mapping to T1190 (Exploit Public-Facing Application) and T1059.004 (Unix Shell) for command execution in an ICS context.

Deeper analysisAI
CVE-2026-25196 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 Wi-Fi SSID and/or password fields, which leads to execution when the configuration is processed. 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).
An authenticated attacker with high privileges can exploit this vulnerability over the network. Exploitation requires high attack complexity but no user interaction, allowing the attacker to inject commands via the specified Wi-Fi configuration fields. Successful exploitation grants remote code execution on the system, with high impacts to confidentiality, integrity, and availability, and a change in scope.
CISA's ICS advisory ICSA-26-057-10 addresses the vulnerability and is available at https://www.cisa.gov/news-events/ics-advisories/icsa-26-057-10, with machine-readable details in CSAF format at https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-057-10.json.
