Description

An OS command injection vulnerability exists in XWEB Pro version 1.12.1 and prior, enabling an authenticated attacker to achieve remote code execution on the system by injecting malicious input into the devices field of the firmware update apply action.

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly prevents OS command injection by validating and sanitizing malicious input in the devices field during firmware update actions.

prevent

Remediates the specific command injection flaw in XWEB Pro firmware update functionality through timely patching.

prevent

Enforces least privilege to restrict high-privilege access required to exploit the firmware update vulnerability.

Security SummaryAI

CVE-2026-24689 is an OS command injection vulnerability (CWE-78) affecting XWEB Pro version 1.12.1 and prior. Published on 2026-02-27, the flaw exists in the firmware update apply action, where malicious input injected into the devices field enables remote code execution on the system. 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).

An authenticated attacker with high privileges can exploit this issue over the network, though it requires high attack complexity and no user interaction. Exploitation allows the attacker to achieve remote code execution, potentially compromising confidentiality, integrity, and availability with changed scope due to the high-impact vector.

CISA ICS Advisory ICSA-26-057-10, the associated CSAF JSON file on GitHub, and the vendor's system software update page on Copeland's webapps site provide further details on the vulnerability and mitigation guidance.

MITRE ATT&CK Enterprise TechniquesAI

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 vulnerability in web-based firmware update feature of XWEB Pro enables remote code execution via exploitation of a public-facing application (T1190) and abuse of command and scripting interpreter (T1059).
