{"id":"CVE-2023-29401","summary":"Improper handling of filenames in Content-Disposition HTTP header in github.com/gin-gonic/gin","details":"The filename parameter of the Context.FileAttachment function is not properly sanitized. A maliciously crafted filename can cause the Content-Disposition header to be sent with an unexpected filename value or otherwise modify the Content-Disposition header. For example, a filename of \"setup.bat";x=.txt\" will be sent as a file named \"setup.bat\". If the FileAttachment function is called with names provided by an untrusted source, this may permit an attacker to cause a file to be served with a name different than provided. Maliciously crafted attachment file name can modify the Content-Disposition header.","aliases":["GHSA-2c4m-59x9-fr2g","GO-2023-1737"],"modified":"2026-08-12T03:51:20.517738363Z","published":"2023-06-08T20:27:15.057Z","database_specific":{"cna_assigner":"Go","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/29xxx/CVE-2023-29401.json"},"references":[{"type":"WEB","url":"https://github.com/gin-gonic/gin/releases/tag/v1.9.1"},{"type":"WEB","url":"https://pkg.go.dev"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2023-1737"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/29xxx/CVE-2023-29401.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-29401"},{"type":"REPORT","url":"https://github.com/gin-gonic/gin/issues/3555"},{"type":"FIX","url":"https://github.com/gin-gonic/gin/pull/3556"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/gin-gonic/gin","events":[{"introduced":"0"},{"fixed":"4ea0e648e38a63d6caff14100f5eab5c50912bcd"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:gin-gonic:gin:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"1.3.1-0.20190301021747-ccb9e902956d"},{"fixed":"1.9.1"}]}}],"versions":["v1.9.0","v1.8.1","v1.8.0","v1.7.1","v1.7.0","v1.6.2","v1.6.1","v1.6.0","v1.5.0","v1.4.0","v1.3.0","v1.2","v1.1.4","v1.1.3","v1.1.2","v1.1.1","v1.1","v1.0-rc.2","v1.0","v1.0rc1","v0.6","v0.5","v0.4","v0.3","v0.2b","v0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-29401.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N"}]}
