GSD-2020-16253

Vulnerability from gsd - Updated: 2020-08-04 00:00

Details

The PgHero dashboard is vulnerable to CSRF with non-session based authentication methods. ## Impact The PgHero dashboard is vulnerable to cross-site request forgery (CSRF). This affects the Docker image, Linux packages, and in specific cases, the Ruby gem. The Ruby gem is vulnerable with non-session based authentication methods like basic authentication - session-based authentication methods (like Devise's default authentication) are not affected. A CSRF attack works by getting an authorized user to visit a malicious website and then performing requests on behalf of the user. In this instance, actions include: 1. Canceling running queries 2. Running `EXPLAIN` on queries (without seeing the results, but can be used for denial of service and other attacks) 3. Resetting query stats (running `pg_stat_statements_reset()`)

Vulnerability from github – Published: 2020-08-05 14:53 – Updated: 2023-08-25 22:21

Summary

PgHero gem allows CSRF

Details

The PgHero gem through 2.6.0 for Ruby allows CSRF. PgHero normally uses the protect_from_forgery method from Rails to prevent CSRF. However, this defaults to :null_session, which has no effect on non-session based authentication methods. Thus the ruby gem is vulnerable with non-session based authentication methods like basic authentication.

Severity ?

8.1 (High)
