CVE-2026-5628: Stack-based Buffer Overflow in Belkin F9K1015
CVE-2026-5628 is a stack-based buffer overflow vulnerability in the Belkin F9K1015 router firmware version 1. 00. 10. The flaw exists in the formSetSystemSettings function within the /goform/formSetSystemSettings component, where manipulation of the webpage argument can trigger the overflow. This vulnerability can be exploited remotely without user interaction and requires low attack complexity and privileges. The vendor has not responded to the disclosure, and no official patch or mitigation guidance is currently available. The vulnerability has a high severity score of 8. 7 and public exploit details have been disclosed, though no known exploits in the wild are reported yet.
AI Analysis
Technical Summary
The Belkin F9K1015 router firmware version 1.00.10 contains a stack-based buffer overflow vulnerability in the formSetSystemSettings function of the Setting Handler component. This occurs due to improper handling of the webpage argument, allowing an attacker to overflow the stack remotely. The vulnerability is remotely exploitable with low complexity and no user interaction, potentially leading to high impact on confidentiality, integrity, and availability. The vendor was notified but has not issued a fix or advisory. No patch or official remediation is currently available.
Potential Impact
Successful exploitation of this vulnerability could allow a remote attacker to execute arbitrary code on the affected device, potentially leading to full compromise of the router. This could impact the confidentiality, integrity, and availability of the device and the network it serves. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vendor has not responded and no official fix is available, users should consider mitigating exposure by restricting remote access to the device management interface and monitoring for suspicious activity. Replacement or upgrade to a different device or firmware version without this vulnerability may be necessary once available.
