{"id":"UBUNTU-CVE-2023-29401","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.","modified":"2026-01-20T17:37:55.525228Z","published":"2023-06-08T21:15:00Z","upstream":["CVE-2023-29401"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-29401"},{"type":"REPORT","url":"https://pkg.go.dev/vuln/GO-2023-1737"},{"type":"REPORT","url":"https://github.com/gin-gonic/gin/releases/tag/v1.9.1"},{"type":"REPORT","url":"https://github.com/gin-gonic/gin/issues/3555"},{"type":"REPORT","url":"https://github.com/gin-gonic/gin/pull/3556"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-29401"},{"type":"REPORT","url":"https://github.com/gin-gonic/gin/commit/2d4bbec941551479b1fdf1e54ece03e6e82a7e72"}],"affected":[{"package":{"name":"golang-github-gin-gonic-gin","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/golang-github-gin-gonic-gin@1.2+dfsg1-2ubuntu1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2+dfsg1-2","1.2+dfsg1-2ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.2+dfsg1-2ubuntu1","binary_name":"golang-github-gin-gonic-gin-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-29401.json"}},{"package":{"name":"golang-github-gin-gonic-gin","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/golang-github-gin-gonic-gin@1.3.0+dfsg1-3?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.0+dfsg1-3"],"ecosystem_specific":{"binaries":[{"binary_version":"1.3.0+dfsg1-3","binary_name":"golang-github-gin-gonic-gin-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-29401.json"}},{"package":{"name":"golang-github-gin-gonic-gin","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/golang-github-gin-gonic-gin@1.6.3-4?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.3-4"],"ecosystem_specific":{"binaries":[{"binary_version":"1.6.3-4","binary_name":"golang-github-gin-gonic-gin-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-29401.json"}},{"package":{"name":"golang-github-gin-gonic-gin","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/golang-github-gin-gonic-gin@1.8.1-2?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.1-1","1.8.1-2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.8.1-2","binary_name":"golang-github-gin-gonic-gin-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-29401.json"}},{"package":{"name":"golang-github-gin-gonic-gin","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/golang-github-gin-gonic-gin@1.8.1-3?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.1-2","1.8.1-3"],"ecosystem_specific":{"binaries":[{"binary_version":"1.8.1-3","binary_name":"golang-github-gin-gonic-gin-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-29401.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N"},{"type":"Ubuntu","score":"low"}]}
