CVE-2026-5612: Stack-based Buffer Overflow in Belkin F9K1015
A vulnerability was determined in Belkin F9K1015 1.00.10. This vulnerability affects the function formWlEncrypt of the file /goform/formWlEncrypt. Executing a manipulation of the argument webpage can lead to stack-based buffer overflow. The attack can be launched remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
AI Analysis
Technical Summary
This vulnerability involves a stack-based buffer overflow in the formWlEncrypt function of the Belkin F9K1015 router firmware version 1.00.10. Specifically, the overflow occurs when the 'webpage' argument passed to the /goform/formWlEncrypt endpoint is manipulated. The flaw allows remote attackers to execute code or cause denial of service due to corrupted memory on the stack. The vulnerability has a CVSS 4.0 score of 8.7, indicating high severity with network attack vector, low attack complexity, no privileges required, and no user interaction needed. The vendor has not issued a patch or advisory, and no official remediation is available.
Potential Impact
Successful exploitation can lead to remote code execution or denial of service on affected Belkin F9K1015 devices running firmware 1.00.10. This compromises device integrity and potentially network security. The vulnerability is exploitable remotely without authentication or user interaction, increasing risk. However, no known exploits in the wild have been reported to date.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vendor has not responded or released a fix, users should consider mitigating exposure by restricting remote access to the affected device's management interface, disabling remote administration if enabled, or replacing the device with a non-affected model. Monitor official Belkin channels for any future updates or patches.
