Description
Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.13.2, Axios HTTP/2 session cleanup logic contains a state corruption bug that allows a malicious server to crash the client process through concurrent session closures. The vulnerability exists in the Http2Sessions.getSession() method in lib/adapters/http.js. The session cleanup logic contains a control flow error when removing sessions from the sessions array. This vulnerability is fixed in 1.13.2.
Analysis
Denial of service in Axios HTTP/2 client before version 1.13.2 allows unauthenticated remote attackers to crash Node.js applications through malicious HTTP/2 server responses that trigger state corruption during concurrent session closures. The vulnerability exploits a control flow error in session cleanup logic with high attack complexity, making real-world exploitation require specific server-side conditions but posing significant risk to applications relying on HTTP/2.
