Published: 27 February 2026
Summary
CVE-2026-24695 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-2026-24695 is an OS command injection vulnerability (CWE-78) affecting XWEB Pro version 1.12.1 and prior versions. Published on 2026-02-27, it allows an authenticated attacker to achieve remote code execution by injecting malicious input into OpenSSL argument fields within requests sent to the utility 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 confidentiality, integrity, and availability impacts with a changed scope.
An authenticated attacker with high privileges can exploit this vulnerability remotely over the network, though it requires high attack complexity. By crafting requests to the utility route with malicious payloads in OpenSSL argument fields, the attacker can inject and execute arbitrary operating system commands, resulting in full remote code execution on the affected system.
CISA has published ICS Advisory ICSA-26-057-10 detailing the vulnerability, with a corresponding CSAF JSON file available on GitHub. Mitigation guidance is provided through the manufacturer's system software update page at webapps.copeland.com/Dixell/Pages/SystemSoftwareUpdate, where patches or updated versions are likely available for deployment.
