DescriptionCVE.org

SpotAuditor 5.3.2 contains a local buffer overflow vulnerability in the Base64 Encrypted Password tool that allows attackers to execute arbitrary code by crafting a malicious payload. Attackers can generate a specially crafted Base64 encoded payload to trigger a Structured Exception Handler (SEH) overwrite and execute shellcode on the vulnerable system.

Executive ViewAI

Why It Matters

SpotAuditor 5.3.2 contains a high-severity local buffer overflow vulnerability (CVE-2019-25336) that enables attackers with local system access to execute arbitrary code. This poses a significant risk to any organization using this tool, particularly those handling sensitive credential data, as compromise could lead to unauthorized access to encrypted passwords and lateral movement within the environment.

Business Impact: High

Compensating Controls

Restrict local system access through endpoint security controls and privilege management; disable or remove the Base64 Encrypted Password tool functionality if operationally feasible; isolate affected systems from sensitive network segments; implement filesystem integrity monitoring and behavioral detection for process execution anomalies; enforce application whitelisting to prevent unauthorized code execution.

Attack Technique

Buffer Overflow HIGH

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.
