leading to remote code execution.

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match
prevent

Directly prevents OS command injection by requiring validation of inputs such as OpenSSL argument fields in utility route requests.

SI-2 Flaw Remediation good match
prevent

Mandates timely flaw remediation through software updates to address the specific vulnerability in XWEB Pro as advised by CISA.

AC-6 Least Privilege partial match
prevent

Enforces least privilege to restrict high-privilege authenticated access to the utility route, limiting exploitation potential.

Security SummaryAI

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.

T1210 Exploitation of Remote Services Lateral Movement
Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network.
attack.mitre.org →
T1059 Command and Scripting Interpreter Execution
Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.
