What is CVE-2024-52796?
CVE-2024-52796 is a medium-severity vulnerability in pglombardo PasswordPusher, published on 20 Nov 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Password Pusher, an open source application to communicate sensitive information over the web, 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. In v1.49.0, a fix was implemented to only authorize proxies on local IPs which resolves this issue. As a workaround, one may add rules to one's proxy and/or firewall to not accept external proxy headers such as `X-Forwarded-*` from clients.
Weakness: CWE-770
