4DescriptionCVE.org
A vulnerability was found in Belkin F9K1015 1.00.10. This affects the function formCrossBandSwitch of the file /goform/formCrossBandSwitch. Performing a manipulation of the argument webpage results in stack-based buffer overflow. The attack can be initiated remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
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. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Belkin F9K1015 firmware version 1.00.10; authenticated access to router administrative interface required; formCrossBandSwitch endpoint must be enabled; webpage parameter parsing vulnerable to unbounded input in stack buffer. Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is HIGH despite requiring authenticated access. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker identifies a Belkin F9K1015 router on a target network through internet-wide scanning (Shodan, Censys) or local network reconnaissance. Using credential stuffing with common default passwords (admin/admin, admin/password) or credentials obtained from prior phishing, the attacker authenticates to the web management interface at http://[router-ip]/goform/formCrossBandSwitch. … |
| Remediation | No vendor-released patch identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Audit all Belkin F9K1015 devices in production and create an inventory by firmware version; immediately isolate or restrict network access to affected routers (v1.00.10) to administrative personnel only. …
