DescriptionNVD

tls-listener is a rust lang wrapper around a connection listener to support TLS. With the default configuration of tls-listener, a malicious user can open 6.4 TcpStreams a second, sending 0 bytes, and can trigger a DoS. The default configuration options make any public service using TlsListener::new() vulnerable to a slow-loris DoS attack. This impacts any publicly accessible service using the default configuration of tls-listener in versions prior to 0.10.0. Users are advised to upgrade. Users unable to upgrade may mitigate this by passing a large value, such as usize::MAX as the parameter to Builder::max_handshakes.

AnalysisAI

tls-listener is a rust lang wrapper around a connection listener to support TLS. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.

Technical ContextAI

This vulnerability is classified as Uncontrolled Resource Consumption (CWE-400), which allows attackers to cause denial of service by exhausting system resources. tls-listener is a rust lang wrapper around a connection listener to support TLS. With the default configuration of tls-listener, a malicious user can open 6.4 TcpStreams a second, sending 0 bytes, and can trigger a DoS. The default configuration options make any public service using TlsListener::new() vulnerable to a slow-loris DoS attack. This impacts any publicly accessible service using the default configuration of tls-listener in versions prior to 0.10.0. Users are advised to upgrade. Users unable to upgrade may mitigate this by passing a large value, such as usize::MAX as the parameter to Builder::max_handshakes. Affected products include: Tmccombs Tls-Listener. Version information: prior to 0.10.0..

RemediationAI
