rsync sanitize_path() Function Arbitrary File Disclosure
Medium Nessus Plugin ID 14223
SynopsisArbitrary files can be accessed from the remote host.
DescriptionAn information disclosure vulnerability exists in rsync due to improper validation of user-supplied input to the sanitize_path() function. An unauthenticated, remote attacker can exploit this, via a specially crafted path, to generated an absolute filename in place of a relative filename, resulting the disclosure of arbitrary files.
However, successful exploitation requires that the rsync daemon is not running chrooted.
Note that since rsync does not advertise its version number and since there are few details about this flaw at this time, this might be a false positive.
SolutionUpgrade to rsync version 2.6.3 or later.
