Description (CNA)
rsync 3.2.0 through 3.2.3 (openssl mode) and rsync-ssl through 3.4.4 (stunnel mode) contain a TLS certificate validation vulnerability that allows on-path attackers to intercept encrypted sessions by presenting self-signed or otherwise invalid certificates. Attackers can exploit the failure to validate server TLS certificates against a trusted CA or verify certificate hostname matching to decrypt or tamper with rsync session content without detection by the client.
Affected (CNA)
| Vendor / product | Versions |
|---|---|
| RsyncProject / rsync | affected 0 through 3.4.4; unaffected 3.5.0 |
