📄 Description (English)

Angry IP Scanner 3.5.3 contains a buffer overflow vulnerability in the preferences dialog that allows local attackers to crash the application by supplying an excessively large string. Attackers can generate a file containing a massive buffer of repeated characters and paste it into the unavailable value field in the display preferences to trigger a denial of service.

🤖 AI Executive Summary

Angry IP Scanner 3.5.3 contains a buffer overflow vulnerability in the preferences dialog that can be exploited by local attackers to cause denial of service. The vulnerability requires user interaction (pasting a malicious string into the display preferences field) and affects the application's stability. While no public exploit is available and the CVSS score is moderate (6.2), organizations using this tool for network scanning should be aware of this local attack vector.

🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations using Angry IP Scanner for network administration and IT operations (particularly in banking, government, and telecom sectors) could experience service disruptions if local users with access to the application exploit this vulnerability. The impact is limited to local denial of service and does not enable remote code execution or data exfiltration. Government agencies (NCA, CITC) and financial institutions (SAMA-regulated banks) that rely on this tool for network diagnostics should assess their usage patterns and user access controls.
