Improper Restriction of Operations within the Bounds of a Memory Buffer


Severity High
Score 7.5/10


Multiple heap-based buffer overflows in (1) isaNVWRequest.dll and (2) relay.dll in Trend Micro ServerProtect Management Console 5.58 and earlier, as used in Control Manager 2.5 and 3.0 and Damage Cleanup Server 1.1, allow remote attackers to execute arbitrary code via "wrapped" length values in Chunked transfer requests. NOTE: the original report suggests that the relay.dll issue is related to a problem in which a Microsoft Foundation Classes (MFC) static library returns invalid values under heavy load. As such, this might not be a vulnerability in Trend Micro's product.

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.
