D-Link DIR-513 Command Injection and Buffer Overflow

Remote code execution in D-Link DIR-513 1.10 via stack-based buffer overflow in the /goform/formEasySetPassword endpoint allows unauthenticated attackers to achieve full system compromise through a malicious curTime parameter. Public exploit code exists for this vulnerability, and affected devices are no longer receiving security updates from the vendor. An attacker with network access can execute arbitrary code with high privileges without user interaction.

OS command injection in D-Link DIR-513 1.10 via the /goform/formSysCmd endpoint allows authenticated remote attackers to execute arbitrary commands with network access. The vulnerability stems from insufficient input validation of the sysCmd parameter and has public exploit code available. No patch is available, and affected devices are no longer supported by D-Link.
