Attackers can send a different X-Forwarded-For value per request to obtain fresh rate-limit buckets, enabling unlimited guessing of login passwords, TOTP codes, and file and URL passwords.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.9,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},{"score":6.5,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},{"score":6.9,"severity":"medium","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"},{"score":6.5,"severity":"medium","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1794439043273,"publishedAt":1794437599421,"references":[{"source":"CNA: VulnCheck","tags":["vendor-advisory"],"url":"https://github.com/diced/zipline/security/advisories/GHSA-v938-v8wg-9497"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/diced/zipline/commit/6bac7e6bb18cb37c1d09f91306c1ffbdca00097c"},{"source":"CNA: VulnCheck","tags":["release-notes"],"url":"https://github.com/diced/zipline/releases/tag/v4.8.0"},{"source":"CNA: VulnCheck","tags":["technical-description"],"url":"https://github.com/diced/zipline/blob/v4.7.0/src/server/index.ts#L58-L62"},{"source":"CNA: VulnCheck","tags":["technical-description"],"url":"https://github.com/diced/zipline/blob/v4.7.0/src/server/startup/plugins.ts#L70-L73"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/zipline-4.3.2-before-4.8.0-rate-limit-bypass-via-spoofed-x-forwarded-for"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/diced/zipline/blob/v4.7.0/src/server/index.ts#L58-L62"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/diced/zipline/blob/v4.7.0/src/server/startup/plugins.ts#L70-L73"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/diced/zipline/commit/6bac7e6bb18cb37c1d09f91306c1ffbdca00097c"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/diced/zipline/releases/tag/v4.8.0"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/diced/zipline/security/advisories/GHSA-v938-v8wg-9497"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://www.vulncheck.com/advisories/zipline-4.3.2-before-4.8.0-rate-limit-bypass-via-spoofed-x-forwarded-for"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
