CVE-2026-6799 is a command injection vulnerability in the Comfast CF-N1-S device version 2. 6. 0. 1. The flaw exists in the /cgi-bin/mbox-config endpoint when manipulating the 'destination' argument in the ping_config section. This vulnerability can be exploited remotely without user interaction or privileges. Public exploit code is available, but the vendor has not responded or provided a fix. The CVSS 4. 0 base score is 5. 3, indicating a medium severity level.
AI Analysis
Technical Summary
This vulnerability allows remote attackers to perform command injection via the 'destination' parameter in the /cgi-bin/mbox-config?method=SET§ion=ping_config endpoint of Comfast CF-N1-S firmware version 2.6.0.1. Successful exploitation could enable execution of arbitrary commands on the affected device. The vendor has not issued any advisory or patch, and no official remediation is currently available. The vulnerability has a CVSS 4.0 score of 5.3, reflecting medium severity with network attack vector, low attack complexity, and no required privileges or user interaction.
Potential Impact
An attacker can remotely execute arbitrary commands on the affected device by exploiting the command injection vulnerability. This could lead to unauthorized control over the device, potentially impacting device integrity and availability. However, no known exploits in the wild have been reported, and the vendor has not provided any mitigation or patch.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vendor has not responded or issued a fix, users should consider restricting network access to the device's management interface to trusted sources only and monitor for suspicious activity. Avoid exposing the device's management interface to untrusted networks until a patch or official guidance is available.
