the parameters route.
Mitigating Controls (NIST 800-53 r5)AI
Directly prevents OS command injection by requiring validation of malicious inputs in the map filename field during upload.
Mitigates the vulnerability through timely flaw remediation via vendor patches for affected XWEB Pro versions.
Enforces restrictions on filename inputs to block malicious payloads that enable command injection in the parameters route.
Security SummaryAI
CVE-2026-20902 is an OS command injection vulnerability (CWE-78) present in XWEB Pro version 1.12.1 and prior versions. The issue allows malicious input to be injected into the map filename field during the map upload action within the parameters route, potentially leading to remote code execution on the affected system. Published on 2026-02-27, it 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).
An authenticated attacker with high privileges (PR:H) can exploit this vulnerability remotely over the network (AV:N), though it requires high attack complexity (AC:H) and involves no user interaction (UI:N). Exploitation changes the scope (S:C) and enables high-impact remote code execution, compromising confidentiality, integrity, and availability (C:H/I:H/A:H) on the target system.
CISA's ICS Advisory ICSA-26-057-10 and the associated CSAF document detail the vulnerability, while the vendor's system software update page at webapps.copeland.com provides relevant mitigation information, including patches for affected XWEB Pro versions.
