Vulnerability from github – Published: 2024-08-12 15:30 – Updated: 2024-08-12 18:30

Details

The lack of validation described above gives rise to a confused deputy problem. For example, a program copying files from an NFS mount could be tricked into copying from outside the intended source directory, and/or to a location outside the intended destination directory.

Severity

5.3 (Medium)

CVE-2024-6759 (GCVE-0-2024-6759)

Vulnerability from cvelistv5 – Published: 2024-08-11 02:45 – Updated: 2024-08-16 17:02

Title

NFS client accepts file names containing path separators

Summary

When mounting a remote filesystem using NFS, the kernel did not sanitize remotely provided filenames for the path separator character, "/". This allows readdir(3) and related functions to return filesystem entries with names containing additional path components. The lack of validation described above gives rise to a confused deputy problem. For example, a program copying files from an NFS mount could be tricked into copying from outside the intended source directory, and/or to a location outside the intended destination directory.

Severity

5.3 (Medium)
