CyberRota Analysis
AI-GeneratedRsync versions prior to 3.5.0 are vulnerable to an access control bypass that allows remote attackers to exploit DNS resolution failures, enabling them to circumvent hostname-based deny rules. This could lead to unauthorized access to restricted module file trees, posing significant risks to systems relying on these access controls. Organizations using affected versions of rsync should prioritize upgrading to mitigate potential exploitation.

Original NVD Description
rsync 3.1.0 before 3.5.0 contains an access control bypass vulnerability that allows remote attackers to circumvent hosts deny rules by inducing DNS resolution failures during hostname-based access control evaluation. When a DNS lookup for a hostname-based deny rule fails, the daemon skips the rule rather than defaulting to a deny decision, enabling attackers who can trigger DNS failures to bypass module-level IP access controls and gain unauthorized access to restricted module file trees.
