The flaw only occurs in non-default logging configurations where administrators explicitly use CustomLog directives with %{varname}x or %{varname}c to log mod_ssl variables like SSL_TLS_SNI, which limits the exposure. While an attacker-controlled TLS client can inject escape or control characters into the logs, potentially leading to log injection or misleading log entries, this does not allow execution of arbitrary code or compromise of the server itself. Furthermore, successful exploitation requires the attacker to craft specific TLS-level parameters, and there are no direct security consequences unless the logs are processed by downstream systems that are themselves vulnerable.", "threat_severity": "Moderate"}
