Description
Cudy TR3000 before 2.5.42 contains a stack buffer overflow vulnerability in an obuspa getter for the TR-098 WLANConfiguration KeyPassphrase parameter, which copies the stored value with strcpy() into a 4,096-byte stack buffer without a length check. A malicious or compromised ACS can set a 5,000-byte passphrase via SetParameterValues, and a later read of the parameter overflows the buffer and crashes obuspa, causing denial of service.
