Vulnerability from variot
A stack-based buffer overflow was found on the D-Link DIR-842 REVC with firmware v3.13B09 HOTFIX due to the use of strcpy for LOGINPASSWORD when handling a POST request to the /MTFWU endpoint. D-Link DIR-842 REVC Is vulnerable to out-of-bounds writes.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. D-Link DIR-842 REVC is a wireless router from Taiwan D-Link Corporation. The vulnerability originates from a network system or product that incorrectly validates data boundaries when performing operations on memory, causing incorrect read and write operations to be performed on other associated memory locations. An attacker could use this vulnerability to cause a buffer overflow or heap overflow
