Description (CNA)
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.
Affected (CNA)
| Vendor / product | Versions |
|---|---|
| RsyncProject / rsync | affected 0 through 3.4.4; unaffected 3.5.0 |
