Description
rsync before 3.5.0Â contains multiple command and argument injection vulnerabilities that allow attackers to execute arbitrary commands by supplying malicious input through several code paths, including 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 arbitrary commands under the privileges of the rsync process or the invoking user.
Weaknesses (CWE)
- CWE-78 — Improper Neutralization of Special Elements used in an OS Command
- CWE-88 — Improper Neutralization of Argument Delimiters in a Command
