3DescriptionCVE.org
rsync before 3.5.0 contains a filter rule bypass vulnerability that allows authenticated clients to override module-level filter restrictions by supplying malicious --filter merge file directives. Attackers can inject client-side merge file directives during filter evaluation to introduce rules that supersede daemon module-level restrictions, gaining access to files the module filter was intended to exclude.
AnalysisAI
Filter rule bypass in rsync before 3.5.0 allows remote clients connecting to an rsync daemon to override module-level filter restrictions by injecting malicious --filter merge file directives during filter evaluation. The daemon's intended access controls - designed to restrict which files a module exposes - can be circumvented, granting the attacker read and limited write access to files the module filter was meant to exclude. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network access to an rsync daemon (rsyncd) listening on TCP port 873 or equivalent. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) indicates low-complexity, unauthenticated network exploitation, but this conflicts with the description's reference to 'authenticated clients' - the actual authentication requirement depends on whether the target rsync module is configured to require credentials, which is not universal. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with network access to an exposed rsync daemon constructs a sync request that includes a malicious --filter merge file directive pointing to a client-controlled rule file. During filter evaluation, the daemon processes this directive, injecting rules that override the module-level restrictions, and the attacker gains read access to files outside the intended module scope - such as SSH keys, configuration files, or sensitive data directories that the module filter was designed to exclude. … |
| Remediation | Upgrade rsync to version 3.5.0 or later, which the RsyncProject has designated as a major security release. … Detailed patch versions, workarounds, and compensating controls in full report. |
