CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
Exploitability: 2.5 / Impact: 5.2
Source: 134c704f-9b21-4f2e-91b3-4a467353bcc0 (Secondary)
Description
DBD::File versions before 1.651 for Perl do not ensure the table file is not a symlink to an untrusted location.
The complete_table_name method builds the absolute table file path without checking whether the file is a symbolic link. A link inside the data directory can point to a table file at any path outside of the configured f_dir and f_dir_search directories.
Callers of file-based drivers can read or write files outside of the data directory.

CWE-59
Improper Link Resolution Before File Access ('Link Following')
