CVE-2019-25434

7.5

Nsasoft · SpotAuditor

SpotAuditor 5.3.1.0 is vulnerable to a stack-based buffer overflow in the registration name field, allowing unauthenticated attackers to cause a denial of service via excessive input.

Executive summary

A stack-based buffer overflow in SpotAuditor 5.3.1.0 allows unauthenticated attackers to crash the application, resulting in a denial of service.

Vulnerability

The application fails to perform adequate bounds checking on the registration name field, allowing an unauthenticated attacker to inject a large string of characters that triggers an unhandled exception and crashes the process.

Business impact

Successful exploitation results in a denial of service, which renders the application unavailable to legitimate users. While the CVSS score of 7.5 indicates a high severity for availability impact, the primary business risk involves the disruption of auditing services and the potential for service instability during the registration phase.

Remediation

Immediate Action: Users should update to the latest available version of SpotAuditor provided by Nsasoft to resolve this buffer overflow vulnerability.

Proactive Monitoring: Security teams should monitor system logs for unusual application crashes or repeated exception errors associated with the registration module.

Compensating Controls: Deploy endpoint protection solutions capable of detecting and blocking buffer overflow attempts or memory corruption exploits targeting local applications.

Exploitation status

Public Exploit Available: Yes, a proof-of-concept script for Windows is available via Exploit-DB (EDB-ID 47494).

Analyst recommendation

Given the availability of a public proof-of-concept, the risk of exploitation is elevated. Organizations should prioritize updating the software to a patched version to eliminate this memory corruption flaw and maintain service continuity. If an update is not immediately feasible, restrict access to the registration functionality to trusted personnel.
