This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Quest NetVault Backup 11.2.0.13. Authentication is not required to exploit this vulnerability. The specific flaw exists within nvwsworker.exe. When parsing the boundary header of a multipart request, the process does not properly validate the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code under the context of SYSTEM. Was ZDI-CAN-4215.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
