Recommendation: Plan a near-term fix — a public PoC already exists.

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.
