AI Analysis
Technical Summary
This vulnerability affects the Baicells EG3661M device, specifically the LuCI Web Interface component accessed via /cgi-bin/luci. By manipulating the MaxHops, Timeout, or Size parameters, an attacker can perform OS command injection remotely. The vulnerability has a CVSS 4.0 base score of 8.6, indicating high severity with network attack vector, low attack complexity, no user interaction, and high impact on confidentiality, integrity, and availability. The vendor was contacted but did not respond, and no patch or mitigation is currently documented.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary operating system commands on the affected device, potentially leading to full compromise of the system's confidentiality, integrity, and availability. This could result in unauthorized control over the device and disruption of its intended functions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vendor has not responded and no official fix is available, users should consider restricting access to the LuCI Web Interface and monitor for suspicious activity as interim measures.
