Iperius Backup Local Overflow: Code Execution via Malicious File Path
The National Vulnerability Database has detailed CVE-2018-25261, a critical local buffer overflow vulnerability impacting Iperius Backup version 5.8.1. This flaw resides within the structured exception handling (SEH) mechanism. Attackers with local access can exploit this by crafting a backup job that points to a malicious external file path. When the backup process initiates, this crafted payload triggers a buffer overflow, allowing for arbitrary code execution with the application’s privileges.
What This Means For You
- If your organization uses Iperius Backup 5.8.1, you must patch this immediately. Local attackers, even with standard user privileges, can gain code execution. Review your systems for any unauthorized backup jobs or suspicious file path configurations.
