DescriptionNVD

A path traversal vulnerability exists in rsync. It stems from behavior enabled by the --inc-recursive option, a default-enabled option 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.

AnalysisAI

Server-to-client path traversal in rsync lets a malicious or compromised rsync server write files outside the client's intended destination directory by abusing the --inc-recursive incremental-recursion mode. Because the server can negotiate --inc-recursive even when the client does not request it, missing symlink validation combined with per-file-list deduplication allows arbitrary file placement on the connecting client. Publicly available exploit code exists, EPSS is 3.19% (87th percentile), and Red Hat has shipped fixes, but it is not currently listed in CISA KEV.

Technical ContextAI

rsync is a near-universal file-synchronization utility for Unix/Linux that transfers file lists between a client and a server (daemon or remote shell). The flaw lives in the incremental-recursion code path enabled by --inc-recursive, which streams the file list in chunks rather than building it all at once. CWE-22 (Improper Limitation of a Pathname to a Restricted Directory) is the root-cause class: deduplication checks are performed per individual file-list segment, and symlinks are not properly re-verified across those segments, so a server-supplied path or symlink can resolve outside the client's destination root. The CPE set (cpe:2.3:a:samba:rsync plus AlmaLinux 8/9/10, Arch, Gentoo, NixOS, SUSE, SmartOS, and Red Hat Enterprise Linux 8) reflects that this is an upstream rsync defect inherited by virtually every Linux/Unix distribution that ships rsync.

RemediationAI

Patch available per vendor advisory: apply the rsync update from your distribution's security errata - for Red Hat ecosystems use the relevant RHSA listed at https://access.redhat.com/security/cve/CVE-2024-12087 (e.g., RHSA-2025:2600 and the later RHSA-2025:23xxx series), and pull the corresponding fixed packages on AlmaLinux, SUSE, Arch, Gentoo, NixOS, and SmartOS as they republish the upstream fix. Exact patched rsync version numbers are not present in the provided input, so confirm the fixed version directly from your vendor's advisory rather than assuming one. Until patched, the most effective compensating control is to only run rsync against trusted servers - avoid pulling from untrusted or internet-exposed rsync daemons; where feasible, disable incremental recursion on pulls by passing --no-inc-recursive, accepting the trade-off of higher memory use and slower start on large trees (and noting a malicious server may still attempt to negotiate behavior, so treat this as risk-reduction, not a guarantee). Additionally restrict and monitor destination directories, and run client-side rsync as an unprivileged user to limit where stray writes can land.
