Improper Restriction of Operations within the Bounds of a Memory Buffer
Multiple stack-based buffer overflows in msg_server.exe in SAP NetWeaver ABAP 7.x allow remote attackers to cause a denial of service (crash) and execute arbitrary code via a (1) long parameter value, (2) crafted string size field, or (3) long Parameter Name string in a package with opcode 0x43 and sub opcode 0x4 to TCP port 3900.
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.
