CyberRota Analysis
AI-GeneratedThe rsync daemon prior to version 3.5.0 is vulnerable to an IP address spoofing flaw that enables unauthenticated remote attackers to bypass IP-based access controls by exploiting a crafted PROXY protocol header. This vulnerability allows attackers to inject a forged source IP, granting unauthorized access to systems that would typically deny their real source address. Organizations using affected versions of rsync should prioritize immediate updates to mitigate the risk of unauthorized access.

Original NVD Description
rsync daemon before 3.5.0 contains an IP address spoofing vulnerability that allows unauthenticated remote attackers to bypass IP-based access controls by sending a crafted PROXY protocol header with a forged source address. Attackers who can connect directly to the rsync daemon can inject a spoofed source IP in the PROXY protocol header to circumvent hosts allow/deny rules, gaining unauthorized access that would otherwise be blocked based on their real source address.
