AI Analysis
Technical Summary
The vulnerability in EFM ipTIME AX8004M version 15.09.0 involves improper sanitization of the fname argument in the /cgi/d.cgi CGI endpoint, which is passed to the popen function. This leads to OS command injection (CWE-77), allowing remote attackers to execute arbitrary commands on the device without authentication. The vulnerability is remotely exploitable with low attack complexity and no privileges or user interaction required. Public exploit details have been disclosed, but no vendor response or patch is currently available.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary operating system commands on the affected device, potentially leading to information disclosure, integrity compromise, and availability disruption. The CVSS score of 7.3 reflects a moderate level of impact with confidentiality, integrity, and availability all affected.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vendor has not responded and no patch links are available, users should consider disabling the vulnerable CGI endpoint or restricting access to the device's management interface to trusted networks until an official fix is released.
