{"id":"CVE-2024-52796","aliases":["GHSA-ffp2-8p2h-4m5j"],"url":"https://o3.security/vulnerability/CVE-2024-52796","summary":"Password Pusher's rate limiter can be bypassed by forging proxy headers","details":"### Impact\n\nPassword Pusher comes with a configurable rate limiter.  In versions prior to [v1.49.0](https://github.com/pglombardo/PasswordPusher/releases/tag/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.\n\nAdditionally, with the ability to bypass rate limiting, it also allows attackers to more easily execute brute force attacks.\n\n### Patches\n\nIn [v1.49.0](https://github.com/pglombardo/PasswordPusher/releases/tag/v1.49.0), a fix was implemented to only authorize proxies on local IPs which resolves this issue.\n\nIf you are running a remote proxy, please see [this documentation](https://docs.pwpush.com/docs/proxies/#trusted-proxies) on how to authorize the IP address of your remote proxy.\n\n### Workarounds\n\nIt is highly suggested to upgrade to at least [v1.49.0](https://github.com/pglombardo/PasswordPusher/releases/tag/v1.49.0) to mitigate this risk.\n\nIf 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.\n\n### References\n\nThe new settings are [configurable to authorize remote proxies](https://docs.pwpush.com/docs/proxies/#trusted-proxies).\n\n### Credits\n\nThank you to [Positive Technologies](https://www.ptsecurity.com/ww-en/) for reporting and working with me to bring this CVE to the community with the associated fix.\n","published":"2024-11-20T16:15:19.478Z","modified":"2026-08-12T03:51:49.129953473Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"RubyGems","name":"pwpush","fixedVersion":"1.49.0"}],"fix":null,"references":[{"type":"WEB","url":"https://docs.pwpush.com/docs/proxies/#trusted-proxies"},{"type":"WEB","url":"https://github.com/pglombardo/PasswordPusher/releases/tag/v1.49.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/52xxx/CVE-2024-52796.json"},{"type":"ADVISORY","url":"https://github.com/pglombardo/PasswordPusher/security/advisories/GHSA-ffp2-8p2h-4m5j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-52796"},{"type":"PACKAGE","url":"https://github.com/pglombardo/PasswordPusher"},{"type":"WEB","url":"https://github.com/rubysec/ruby-advisory-db/blob/master/gems/pwpush/CVE-2024-52796.yml"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:49.129953473Z"}}
