Iperius Backup version 5.8.1 contains a local buffer overflow vulnerability in the structured exception handling (SEH) mechanism. The vulnerability allows local attackers to execute arbitrary code by supplying a malicious file path. Attackers can create a backup job with a crafted payload in the external file location field that triggers a buffer overflow when the backup job executes. This enables code execution with application privileges, posing a significant security risk to systems running the affected software.
