Detailsinfo

A vulnerability was found in RsyncProject rsync up to 3.4.4. It has been declared as problematic. Affected by this vulnerability is an unknown function of the component Input Configuration File Handler. The manipulation of the argument files-from/password-file/filter merge files with an unknown input leads to a symlink vulnerability. The CWE definition for the vulnerability is CWE-61. The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files. As an impact it is known to affect confidentiality. The summary by CVE is:

rsync before 3.5.0 contains an arbitrary file read vulnerability that allows attackers to read files accessible to the rsync daemon process by exploiting symlink following in input configuration file handling including --files-from, --password-file, and filter merge files. Attackers can place a symlink at a predictable --files-from or --password-file path, or supply a --files-from path that escapes the daemon module root, to read arbitrary files accessible to the rsync process.
