Attack: GSM SIM Utility .sms File Buffer Overflow Vulnerability

Severity: High

This attack could pose a serious security threat. You should take immediate action to stop any damage or prevent further damage from happening.


This signature detects attempts to exploit a buffer overflow vulnerability in GSM SIM Utility which could result in remote code execution.

Additional Information

GSM SIM Utility is a SIM card cloning software.

The application is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. This issue occurs when handling specially crafted '.sms' files.

Successful exploits allow remote attackers to execute arbitrary code in the context of the application. Failed exploit attempts likely result in denial-of-service conditions.


  • GSM SIM Utility 5.15 is vulnerable; other versions may be affected as well.
