CVE-2024-12087

The rsync software is affected by a path traversal issue, which arises from the behavior enabled by the --inc-recursive option. This option is default-enabled for many client options and can be enabled by the server even if not explicitly enabled by the client. When using the --inc-recursive option, a lack of proper symlink verification coupled with deduplication checks occurring on a per-file-list basis could allow a server to write files outside of the client's intended destination directory. A malicious server could write malicious files to arbitrary locations named after valid directories/paths on the client. The affected software is rsync, but the specific vulnerable versions are not specified in the given text. An exploit could potentially be used to write malicious files to arbitrary locations on the client's system. #rsync #pathtraversal #remoteserver #maliciousfiles #symlinkverification #deduplicationchecks #increcursiveoption #securityrisk #maliciousserver
