CVE-2024-41270Network attack vector

Traffic interception via deprecated TLS negotiation

Published Aug 6, 2024 · Updated Aug 7, 2024

Deprecated TLS support in appleboy gorush before 1.18.5 allows man-in-the-middle attackers to intercept and alter HTTPS traffic. RunHTTPServer sets tls.Config.MinVersion to TLS 1.0 when core SSL is enabled, so the server negotiates TLS 1.0 or 1.1 with untrusted clients. Exposure requires the built-in HTTPS server to be enabled and an attacker positioned on the network path; reported impact is limited to traffic confidentiality and integrity.
