Name of the Vulnerable Software and Affected Versions rsync versions prior to 3.5.0
Description Multiple command and argument injection issues allow attackers to execute arbitrary commands by providing malicious input through various code paths. These paths include the RSYNC CONNECT PROG environment variable, daemon hooks, the rsync-ssl wrapper, and remote-shell command newline injection. Attackers can inject shell metacharacters or newline characters into unsanitized user-supplied values, such as hostnames and hostspecs, to execute commands with the privileges of the rsync process or the invoking user.
Recommendations Update to version 3.5.0 or later.
