CVE-2024-39916
FOG is a free open-source cloning/imaging/rescue suite/inventory management system. There is a security issue with the NFS configuration in /etc/exports generated by the installer that allows an attacker to modify files outside the export in the default installation. The exports have the no_subtree_check option. The no_subtree_check option means that if a client performs a file operation, the server will only check if the requested file is on the correct filesystem, not if it is in the correct directory. This enables modifying files in /images, accessing other files on the same filesystem, and accessing files on other filesystems. This vulnerability is fixed in 1.5.10.30.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N
- Base score: 6.4
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.29%
- Percentile among all scored CVEs: 19
- Score date: 10/12/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
