Improper Restriction of Operations within the Bounds of a Memory Buffer
Multiple buffer overflows in the web interface on the D-Link DI-524 router allow remote attackers to cause a denial of service (device crash) or possibly have unspecified other impact via (1) a long username or (2) an HTTP header with a large name and an empty value.
CWE-119 - Buffer Overflow
Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
