Lifecycle Timeline
4DescriptionCVE.org
Nsauditor 3.0.28.0 contains a structured exception handling buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying malicious input to the DNS Lookup tool. Attackers can craft a payload with SEH chain overwrite and inject shellcode through the DNS Query field to achieve code execution with application privileges.
AnalysisAI
Nsauditor 3.0.28.0 contains a structured exception handling buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying malicious input to the DNS Lookup tool. Rated high severity (CVSS 8.6), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. Nsauditor 3.0.28.0 contains a structured exception handling buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying malicious input to the DNS Lookup tool. Attackers can craft a payload with SEH chain overwrite and inject shellcode through the DNS Query field to achieve code execution with application privileges. Affected products include: Nsauditor Nsauditor Local Seh Buffer Overflow.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
