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 configuring a maliciously crafted LCD state which is later processed during system setup, enabling remote code execution.

AnalysisAI

Remote code execution in XWEB Pro firmware versions 1.12.1 and prior allows authenticated attackers to execute arbitrary OS commands by injecting malicious payloads through crafted LCD state configurations that are processed during system initialization. This vulnerability affects Xweb 300d Pro, 500b Pro, and 500d Pro devices and requires high-level privileges to exploit, though the impact extends across connected systems. No patch is currently available for this high-severity vulnerability (CVSS 8.0).
