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 the Wi-Fi SSID and/or password fields can lead to remote code execution when the configuration is processed.

AnalysisAI

Remote code execution in XWEB Pro firmware (versions 1.12.1 and earlier) allows authenticated attackers to execute arbitrary OS commands by injecting malicious payloads into Wi-Fi SSID or password configuration fields. The vulnerability affects multiple Xweb Pro models (300d, 500b, 500d) and requires high privilege access to exploit, though successful exploitation grants complete system compromise across the network. …
