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.

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.
Executive ViewAI
Organizations using Nsauditor 3.0.28.0 face significant risk from CVE-2018-25213, a out-of-bounds write vulnerability rated CVSS 8.6. Exploitation could allow attackers to corrupt memory, crash the application, or potentially execute arbitrary code. Proof-of-concept code is publicly available, increasing the risk of exploitation. Organizations should apply vendor updates when available and consider compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Enable ASLR and DEP where available; (2) Implement network segmentation; (3) Monitor for exploitation indicators.

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.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
