{"cve":"CVE-2024-35175","nvd":{"published":"2024-05-14T22:15:10.213","modified":"2026-06-17T07:34:29.143","status":"Deferred","description":"sshpiper is a reverse proxy for sshd. Starting in version 1.0.50 and prior to version 1.3.0, the way the proxy protocol listener is implemented in sshpiper can allow an attacker to forge their connecting address. Commit 2ddd69876a1e1119059debc59fe869cb4e754430 added the proxy protocol listener as the only listener in sshpiper, with no option to toggle this functionality off. This means that any connection that sshpiper is directly (or in some cases indirectly) exposed to can use proxy protocol to forge its source address. Any users of sshpiper who need logs from it for whitelisting/rate limiting/security investigations could have them become much less useful if an attacker is sending a spoofed source address. Version 1.3.0 contains a patch for the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-345"],"references":["https://github.com/tg123/sshpiper/commit/2ddd69876a1e1119059debc59fe869cb4e754430","https://github.com/tg123/sshpiper/commit/70fb830dca26bea7ced772ce5d834a3e88ae7f53","https://github.com/tg123/sshpiper/security/advisories/GHSA-4w53-6jvp-gg52","https://github.com/tg123/sshpiper/commit/2ddd69876a1e1119059debc59fe869cb4e754430","https://github.com/tg123/sshpiper/commit/70fb830dca26bea7ced772ce5d834a3e88ae7f53"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:49:23.840078609+00:00"},"epss":{"cve":"CVE-2024-35175","score":0.0026,"percentile":0.17729,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-4w53-6jvp-gg52","url":"https://osv.dev/vulnerability/GHSA-4w53-6jvp-gg52","summary":"sshpiper's enabling of proxy protocol without proper feature flagging allows faking source address","modified":"2026-09-10T03:50:13.239534206Z","packages":[{"ecosystem":"Go","name":"github.com/tg123/sshpiper","purl":"pkg:golang/github.com/tg123/sshpiper","ranges":[">=1.0.50 <1.3.0"],"fixed":["1.3.0"]}]},{"id":"GO-2024-2853","url":"https://osv.dev/vulnerability/GO-2024-2853","summary":"sshpiper's enabling of proxy protocol without proper feature flagging allows faking source address in github.com/tg123/sshpiper","modified":"2026-03-03T04:55:22.341464Z","packages":[{"ecosystem":"Go","name":"github.com/tg123/sshpiper","purl":"pkg:golang/github.com/tg123/sshpiper","ranges":[">=1.0.50 <1.3.0"],"fixed":["1.3.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
