AnalysisAIv1 – Mar 12, 2026

Remote code execution in Xweb 300d/500b/500d Pro firmware versions 1.12.1 and earlier allows authenticated attackers to execute arbitrary OS commands by injecting malicious input into the firmware update endpoint. The vulnerability stems from insufficient input validation in command processing and requires high privileges but affects the entire system scope. No patch is currently available for this HIGH severity issue.

DescriptionCVE.org

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 requests sent to the firmware update route.

Executive ViewAI

Why It Matters

XWEB Pro versions 1.12.1 and earlier contain a critical remote code execution vulnerability that allows authenticated users to execute arbitrary commands on affected systems. This poses a significant risk to organizations running vulnerable versions, as compromised systems could be used to launch further attacks, steal data, or disrupt operations.

Business Impact: High
Compensating Controls

Implement Web Application Firewall (WAF) rules to detect and block command injection patterns in firmware update requests; restrict access to firmware update functionality to authorized administrators only via network segmentation or IP whitelisting; disable firmware self-update feature if not operationally critical; enable detailed logging and monitoring of all firmware update attempts; consider running XWEB Pro in a restricted network zone with limited lateral movement capabilities.

Attack Technique

OS Command Injection CRITICAL

OS command injection occurs when an application passes unsanitized user input directly into system shell commands.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
