GHSA-MQJ4-X9GM-M5R5

Vulnerability from github – Published: 2022-05-13 01:44 – Updated: 2025-04-20 03:49

Details

The daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, does not check for fnamecmp filenames in the daemon_filter_list data structure (in the recv_files function in receiver.c) and also does not apply the sanitize_paths protection mechanism to pathnames found in "xname follows" strings (in the read_ndx_and_attrs function in rsync.c), which allows remote attackers to bypass intended access restrictions.

Severity ?

9.8 (Critical)
