- Summary
- Password Pusher rate limiter can be bypassed by forging proxy headers
- Details
-
Impact
Password Pusher comes with a configurable rate limiter. In versions prior to v1.49.0, the rate limiter could be bypassed by forging proxy headers allowing bad actors to send unlimited traffic to the site potentially causing a denial of service.
Additionally, with the ability to bypass rate limiting, it also allows attackers to more easily execute brute force attacks.
Patches
In v1.49.0, a fix was implemented to only authorize proxies on local IPs which resolves this issue.
If you are running a remote proxy, please see this documentation on how to authorize the IP address of your remote proxy.
Workarounds
It is highly suggested to upgrade to at least v1.49.0 to mitigate this risk.
If for some reason you cannot immediately upgrade, the alternative is that you can add rules to your proxy and/or firewall to not accept external proxy headers such as
X-Forwarded-*from clients.References
The new settings are configurable to authorize remote proxies.
