CyberRota Analysis

AI-Generated

Rsync versions prior to 3.5.0 are vulnerable to a filter rule bypass that allows authenticated clients to manipulate module-level filter restrictions through malicious merge file directives. This could enable attackers to access files that should have been restricted by the module's filter rules, potentially exposing sensitive data. Organizations using affected versions of rsync should prioritize updating to mitigate the risk of unauthorized file access.

Original NVD Description

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.
