CyberRota Analysis

AI-Generated

OpenSSL versions used in rsync 3.2.0 to 3.2.3 and rsync-ssl through 3.4.4 are vulnerable to a TLS certificate validation flaw, enabling on-path attackers to intercept and manipulate encrypted sessions by presenting invalid certificates. This vulnerability allows attackers to bypass certificate validation, potentially leading to unauthorized access to sensitive data during rsync operations. Organizations utilizing these versions of rsync should prioritize patching to mitigate the risk of session hijacking and data compromise.

Original NVD Description

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.
