Summary

rsync, when running in daemon mode, does not properly call setgroups before dropping privileges, which could provide supplemental group privileges to local users, who could then read certain files that would otherwise be disallowed.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.

"Ethan Benson discovered a bug in rsync where the supplementary groups
that the rsync daemon runs as (such as root) would not be removed from
the server process after changing to the specified unprivileged uid
and gid. This seems only serious if rsync is called using 'rsync
--daemon' from the command line where it will inherit the group of the
user starting the server (usually root). Note that, by default,
Mandrake Linux uses xinetd to handle connections to the rsync daemon.
This was fixed upstream in version 2.5.3, as well as the previously
noted zlib fixes (see MDKSA-2002:023). The authors released 2.5.4 with
some additional zlib fixes, and all users are encouraged to upgrade to
this new version of rsync."
