CVE-2026-75984: Command Injection in TRENDnet TEW-823DRU
A command injection vulnerability exists in the TRENDnet TEW-823DRU firmware version 1.1.02b01. The flaw is located in an unknown function within /cgi-bin/admin.cgi, where manipulation of the Hostname argument allows remote attackers to execute arbitrary commands. Exploit code is publicly available, but no known active exploitation has been reported. The vulnerability has a CVSS 3.1 base score of 7.4, indicating a high impact on confidentiality, integrity, and availability if exploited.
AI Analysis
Technical Summary
The TRENDnet TEW-823DRU device running firmware 1.1.02b01 contains a command injection vulnerability (CWE-74) in an unspecified function of /cgi-bin/admin.cgi. By manipulating the Hostname parameter, an attacker with low privileges can remotely execute arbitrary commands on the device without user interaction. This vulnerability is remotely exploitable over the network. Public exploit code exists, but there is no evidence of in-the-wild exploitation. The CVSS 3.1 vector is AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:L with a score of 7.4.
Potential Impact
Successful exploitation allows remote attackers with low privileges to execute arbitrary commands on the affected device, potentially leading to partial compromise of confidentiality, integrity, and availability. The vulnerability affects the device's administrative CGI interface, which could be leveraged to control or disrupt device operations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are currently available. Until a vendor fix is released, restrict network access to the device's administrative interface to trusted users only and monitor for suspicious activity related to the Hostname parameter in /cgi-bin/admin.cgi.
