This vulnerability is classified as Buffer Copy without Size Check (CWE-120), which allows attackers to overflow a buffer to corrupt adjacent memory. NetShareWatcher 1.5.8.0 contains a structured exception handler buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying malicious input. Attackers can craft a payload with overwritten SEH and NSEH pointers through the Restrictions custom filter field to trigger code execution when the Find function is invoked. Affected products include: Nsauditor Netsharewatcher.

How this decision was reached
The engine reads each signal below and applies a fixed list of rules from top to bottom. The first rule that matches sets the recommended action – like a statement, every line is shown.
What every action level means
SSVC AssessmentENISA
Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
