Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N

Name of the Vulnerable Software and Affected Versions rsync versions prior to 3.1.3

Description The issue is related to the parse arguments function in options.c in rsyncd, which does not prevent multiple uses of the --protect-args parameter. This allows remote attackers to bypass an argument-sanitization protection mechanism, potentially compromising data integrity.

Recommendations For versions prior to 3.1.3, update to version 3.1.3 or later to resolve the issue. As a temporary workaround, consider restricting the use of the --protect-args parameter in the parse arguments function to minimize the risk of exploitation.
