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 sending malicious input injected into the server username field of the import preconfiguration action in the API V1 route.

AnalysisAI

Remote code execution in XWEB Pro firmware versions 1.12.1 and earlier (affecting Xweb 500b Pro, 500d Pro, and 300d Pro models) allows authenticated attackers to execute arbitrary OS commands by injecting malicious input into the server username field during the import preconfiguration API action. An attacker with administrative privileges can exploit this OS command injection vulnerability to gain complete system compromise. No patch is currently available for this vulnerability.

Technical ContextAI

Classified as CWE-78 (OS Command Injection). Affects Xweb 300D Pro Firmware. 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 sending malicious input injected into the server username field of the import preconfiguration action in the API V1 route.
