Weakness: CWE-209

Description

A flaw was found in Ansible Tower, versions 3.6.x before 3.6.2 and 3.5.x before 3.5.4, when /websocket is requested and the password contains the '#' character. This request would cause a socket error in RabbitMQ when parsing the password and an HTTP error code 500 and partial password disclose will occur in plaintext. An attacker could easily guess some predictable passwords or brute force the password.

Affected products

Tower: from 3.5.0 before 3.5.4; from 3.6.0 before 3.6.2 — fixed in 3.5.4, 3.6.2

How to fix

Upgrade to a fixed version: Tower 3.5.4, 3.6.2. Check the vendor advisory for mitigations.
