Official Description

Iperius Backup 5.8.1 contains a local buffer overflow vulnerability in the structured exception handling (SEH) mechanism that 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, enabling code execution with application privileges.

Technical Analysis

CVE-2018-25261 requires local access, meaning attackers must already have a foothold on the target system.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
