Broken Authentication & Session Management

What is it ? Bad implementation of authentication and session management. If an attacker can get your session ID, then they can steal your session Could happen over unsafe medium. Could happen if an attacker can get your password.

Broken Authentication and Session Management - Vulnerabilities Password not hashed. Weak Password recovery method. Exposed Session-Ids’. Long session timeout. Improper rotation of session-ids’ after logout. Sending session-ids’, passwords over unencrypted connections.

Session Fixation Attack

Broken Authentication and Session Management - Prevention Always use https for any authenticated URLs. If storing credentials in a database, store them encrypted or hashed. Set session timeouts to as low as possible to reduce the risk of exposure to someone who forgets to log out at a public terminal. Try to store SessionIds in cookies Invalidate session properly
