Critical stack-based buffer overflow vulnerability in the D-Link DIR-816 router (version 1.10CNB05) that allows remote attackers to achieve full system compromise without authentication. A public proof-of-concept exploit is available on GitHub, and the vulnerability affects end-of-life products no longer supported by D-Link, making this a high-risk issue for organizations still using these devices.

Critical stack-based buffer overflow vulnerability in the D-Link DIR-816 router (firmware version 1.10CNB05) that allows remote attackers to execute arbitrary code without authentication. A public proof-of-concept exploit is available, and the vulnerability affects end-of-life products no longer supported by D-Link, making this a high-risk issue for organizations still using these devices.

CVE-2026-4180 is an authentication bypass vulnerability in the D-Link DIR-816 router (version 1.10CNB05) affecting the redirect.asp file in the goahead component, allowing remote attackers to gain unauthorized access without authentication. A public proof-of-concept exploit is available and the affected product is no longer supported by D-Link, making this vulnerability permanently unpatched.

D-Link DIR-513 router (v1.10) has a stack buffer overflow in the curTime parameter of formSetWizardSelectMode. This is an end-of-life router with no expected patch, meaning exploitation will remain possible indefinitely.

Remote code execution in D-Link DIR-513 firmware version 1.10 through a stack-based buffer overflow in the /goform/formEasySetupWizard3 endpoint allows unauthenticated attackers to achieve full system compromise over the network. The vulnerability can be exploited with minimal complexity using publicly available exploit code, and no patch is currently available to remediate the issue.
