Belkin F9K1015 Stack Buffer Overflow

2026-04-06

CVE-2026-5628 HIGH POC

Stack-based buffer overflow in Belkin F9K1015 wireless router firmware 1.00.10 allows authenticated remote attackers to achieve arbitrary code execution with high confidentiality, integrity, and availability impact. The vulnerability resides in the formSetSystemSettings function within the /goform/formSetSystemSettings endpoint, exploitable via the 'webpage' parameter. Publicly available exploit code exists (GitHub POC), CVSS 8.8 indicating network-exploitable with low complexity requiring only low-privilege authentication. Vendor unresponsive to coordinated disclosure attempts.

CVE-2026-5610 HIGH POC

Stack-based buffer overflow in Belkin F9K1015 wireless router firmware 1.00.10 enables authenticated remote attackers to achieve full system compromise (code execution, denial of service, credential theft) via crafted requests to the formWISP5G endpoint. CVSS 8.8 severity with low attack complexity and publicly available exploit code. Vendor has not responded to disclosure, leaving users without an official patch. EPSS data not available, but the combination of network accessibility, low complexity, and public POC elevates real-world risk despite requiring low-privilege authentication.

CVE-2026-5613 HIGH POC

Stack-based buffer overflow in Belkin F9K1015 wireless router firmware 1.00.10 allows authenticated remote attackers to achieve code execution and full system compromise via the formReboot endpoint. The vulnerability has a publicly available exploit (GitHub POC) and requires only low-privileged authentication (EPSS risk assessment recommended but data not provided). Vendor did not respond to disclosure, indicating no patch is available.

CVE-2026-5614 HIGH POC

Stack-based buffer overflow in Belkin F9K1015 v1.00.10 allows authenticated remote attackers to achieve code execution via the formSetPassword function. The vulnerability requires low-privilege credentials but no user interaction, carrying a CVSS score of 8.8 (High). Public exploit code exists on GitHub, significantly lowering the barrier to exploitation, though no active exploitation is confirmed (not in CISA KEV). The vendor did not respond to responsible disclosure attempts.

CVE-2026-5611 HIGH POC

Stack-based buffer overflow in Belkin F9K1015 wireless router firmware version 1.00.10 allows authenticated remote attackers to achieve arbitrary code execution with high confidentiality, integrity, and availability impact. The vulnerability resides in the formCrossBandSwitch function accessible via /goform/formCrossBandSwitch endpoint, where unsanitized input to the 'webpage' parameter triggers memory corruption. Publicly available exploit code exists (GitHub POC), elevating practical exploitat

CVE-2026-5612 HIGH POC

Stack-based buffer overflow in Belkin F9K1015 wireless router firmware 1.00.10 enables authenticated remote attackers to achieve complete system compromise via crafted 'webpage' parameter to the formWlEncrypt endpoint. Publicly available exploit code exists (GitHub POC). EPSS data not provided, but the low attack complexity (AC:L) and network attack vector (AV:N) combined with confirmed POC availability indicate moderate-to-high exploitation risk. Vendor was notified but did not respond, leaving devices potentially unpatched.
