CyberRota Analysis
AI-GeneratedRsync versions prior to 3.5.0 are vulnerable due to an authorization bypass in the auth users directive parsing, which improperly handles group names containing spaces. This flaw allows authenticated users, who should be denied access based on group membership, to connect to restricted modules, potentially leading to unauthorized data exposure. Organizations utilizing affected rsync versions should prioritize patching to mitigate this high-severity vulnerability.

Original NVD Description
rsync 3.1.0 before 3.5.0 contains an authorization bypass in auth users directive parsing. The auth users parser uses comma-only tokenization when splitting the user list, which fails to correctly handle entries of the form @Group Name where the group name contains a space. The space within the group name causes the parser to split the entry at the space boundary, discarding the deny rule associated with the group. An authenticated user whose username or group membership would be denied by an @Group Name auth users entry can connect to a restricted module because the deny rule is silently discarded during parsing.
