CVE-2026-8345: Command Injection in D-Link DIR-816
CVE-2026-8345 is a command injection vulnerability in the D-Link DIR-816 router firmware version 1.10CNB05_R1B011D88210. The issue exists in the /goform/singlePortForward endpoint, specifically in the function sub_445E7C, where manipulation of the ip_address argument can lead to remote command injection. The vulnerability allows an attacker to execute arbitrary commands on the affected device without user interaction. The exploit has been publicly disclosed but there are no known exploits in the wild at this time. The vulnerability has a medium severity rating with a CVSS 4.0 base score of 5.3. No official patch or remediation guidance has been provided by the vendor yet.
AI Analysis
Technical Summary
This vulnerability involves a command injection flaw in the D-Link DIR-816 router firmware 1.10CNB05_R1B011D88210. The flaw is located in the function sub_445E7C within the /goform/singlePortForward file, where the ip_address parameter is not properly sanitized, allowing remote attackers to inject and execute arbitrary commands. The vulnerability can be exploited remotely without authentication or user interaction. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required, no user interaction, and low to low impact on confidentiality, integrity, and availability. The vulnerability is publicly disclosed but no official fix or patch is currently documented.
Potential Impact
Successful exploitation of this vulnerability could allow remote attackers to execute arbitrary commands on the affected router, potentially compromising the device's integrity and availability. However, the impact is rated medium due to low confidentiality, integrity, and availability impacts as per the CVSS vector. There are no known active exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or workaround has been provided, users should monitor D-Link's official channels for updates. Until a fix is available, restricting access to the router's management interface from untrusted networks and disabling remote management features, if possible, may reduce exposure.
