Privilege escalation in Enter’s Iperius Backup
Iperius Backup, version 8.8.3 for Windows.
INCIBE has coordinated the disclosure of a high severity vulnerability affecting Enter’s Iperius Backup, a Windows backup programme. The vulnerability was discovered by Jonas Fernández.
This vulnerability has been assigned the following code, CVSS v4.0 base score, CVSS vector and CWE vulnerability type:
- CVE-2026-112174: CVSS v4.0: 9.3 | CVSS:4.0 AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H | CWE-250
Update to Iperius Backup 8.8.9. According to the manufacturer, this version includes restrictive permissions by default that prevent the vulnerability. When the service is installed, it applies these permissions to the configuration folders and prevents non-administrator users from creating, modifying or running backup jobs.
CVE-2026-112174: local privilege escalation vulnerability in Iperius Backup 8.8.3, due to insufficient separation between the graphical user interface running with elevated privileges and local users with low privileges. When the backup service is configured to run persistently with Administrator privileges, a local attacker with low privileges can use the native Windows dialogues exposed by the application to run programmes that inherit its elevated context. This allows commands to be executed with SYSTEM or Administrator privileges, depending on the application’s context, and compromises the affected Windows system.
