Has PoC?





  • Lack of valid SSL/TLS


The continued support of TLS 1.0 poses a severe security risk by potentially allowing attackers to decrypt sensitive data transferred over the network.

Vulnerability Details

The website "https://basin.exchange/" supports TLS 1.0, a cryptographic protocol designed to provide communications security over a computer network. Despite its initial purpose, TLS 1.0 is now deprecated due to inherent vulnerabilities that expose it to several attack vectors, including but not limited to cipher block chaining (CBC) attacks and protocol downgrade attacks.

Impact Details

An attacker positioned as a man-in-the-middle could exploit the known vulnerabilities in TLS 1.0 to decrypt or alter the communications, potentially stealing sensitive data or injecting malicious content into the sessions.
