Man-in-the-Middle Vulnerability in JetBrains Ktor Framework

CVE-2019-10102

Summary

The JetBrains Ktor framework, utilized in development with the Kotlin IDE, contains a security flaw in versions prior to 1.1.0. During the build process, the framework resolves artifacts over an unsecured HTTP connection, opening the door for potential Man-in-the-Middle (MITM) attacks. By exploiting this vulnerability, an attacker could intercept or alter communications between the client and server, leading to unauthorized access or data tampering. This issue was addressed and remedied in the Kotlin plugin version 1.3.30, highlighting the importance of using secure connections in development environments.
