Vulnerability from variot
An issue was discovered in ASUSWRT 3.0.0.4.384.20308. There is a stack-based buffer overflow issue in parse_req_queries function in wanduck.c via a long string over UDP, which may lead to an information leak. ASUSWRT Contains a classic buffer overflow vulnerability.Information may be obtained. ASUS Asuswrt-Merlin is a firmware that runs in its router from Taiwan's ASUS Corporation (ASUS).
ASUS Asuswrt-Merlin 3.0.0.4.384.20308 version of the wanduck.c file ‘parse_req_queries’ function has a buffer overflow vulnerability. The vulnerability stems from the fact that when a network system or product performs an operation on memory, the data boundary is not correctly verified, resulting in an incorrect read and write operation to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow
