A security flaw has been discovered in D-Link DIR-825 up to 2.10. Affected by this vulnerability is the function sub4106d4 of the file apply.cgi. The manipulation of the argument countdowntime results in buffer overflow. The attack can be executed remotely. The exploit has been released to the public and may be exploited. This vulnerability only affects products that are no longer supported by the maintainer.

A vulnerability was identified in D-Link DIR-825 2.10. Affected by this vulnerability is the function getpingappstat of the file pingresponse.cgi of the component httpd. The manipulation of the argument pingipaddr leads to stack-based buffer overflow. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. This vulnerability only affects products that are no longer supported by the maintainer.

An issue was discovered on D-Link DIR-825 R1 devices through 3.0.1 before 2020-11-20. A buffer overflow in the web interface allows attackers to achieve pre-authentication remote code execution.

Unauthenticated remote code execution occurs in D-Link products such as DIR-655C, DIR-866L, DIR-652, and DHP-1565. The issue occurs when the attacker sends an arbitrary input to a "PingTest" device common gateway interface that could lead to common injection. An attacker who successfully triggers the command injection could achieve full system compromise. Later, it was independently found that these are also affected: DIR-855L, DAP-1533, DIR-862L, DIR-615, DIR-835, and DIR-825.
