CVE-2026-75094: OS Command Injection in COMFAST CF-N1-S
CVE-2026-75094 is a critical OS command injection vulnerability in the COMFAST CF-N1-S device version 2.6.0.1. The flaw exists in the CGI interface component, specifically in the sub_44B438 function handling the /cgi-bin/mbox-config?method=SET§ion=ptest_ssid endpoint. An attacker can remotely exploit this by manipulating the ssid argument to execute arbitrary OS commands. Exploit code has been published, increasing the risk of exploitation.
AI Analysis
Technical Summary
The vulnerability CVE-2026-75094 affects COMFAST CF-N1-S version 2.6.0.1. It is an OS command injection flaw in the CGI interface, within the sub_44B438 function of the /cgi-bin/mbox-config?method=SET§ion=ptest_ssid endpoint. By manipulating the ssid parameter, an attacker can inject OS commands remotely without user interaction and with high privileges. The CVSS 4.0 score is 9.4 (critical), reflecting the high impact and ease of exploitation. Exploit code has been publicly released.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary operating system commands on the affected device with high privileges, potentially leading to full system compromise. The vulnerability requires no user interaction and has a low attack complexity, making it highly dangerous. The published exploit increases the likelihood of active attacks.
Mitigation Recommendations
No official patch or remediation information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the vulnerable CGI interface endpoint and monitor for suspicious activity targeting this parameter.
