{"id":"UBUNTU-CVE-2022-45060","details":"An HTTP Request Forgery issue was discovered in Varnish Cache 5.x and 6.x before 6.0.11, 7.x before 7.1.2, and 7.2.x before 7.2.1. An attacker may introduce characters through HTTP/2 pseudo-headers that are invalid in the context of an HTTP/1 request line, causing the Varnish server to produce invalid HTTP/1 requests to the backend. This could, in turn, be used to exploit vulnerabilities in a server behind the Varnish server. Note: the 6.0.x LTS series (before 6.0.11) is affected.","modified":"2026-04-22T13:32:11.618276Z","published":"2022-11-09T06:15:00Z","related":["USN-7372-1"],"upstream":["CVE-2022-45060"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-45060"},{"type":"REPORT","url":"https://varnish-cache.org/security/VSV00011.html"},{"type":"REPORT","url":"https://github.com/varnishcache/varnish-cache/commit/515a93df894430767073ccd8265497b6b25b54b5"},{"type":"REPORT","url":"https://docs.varnish-software.com/security/VSV00011"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-45060"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7372-1"}],"affected":[{"package":{"name":"varnish","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/varnish@5.2.1-1ubuntu0.1+esm1?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.2.1-1ubuntu0.1+esm1"}]}],"versions":["5.0.0-7.1","5.2.1-1","5.2.1-1ubuntu0.1"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_version":"5.2.1-1ubuntu0.1+esm1","binary_name":"libvarnishapi1"},{"binary_version":"5.2.1-1ubuntu0.1+esm1","binary_name":"varnish"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-45060.json"}},{"package":{"name":"varnish","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/varnish@6.2.1-2ubuntu0.2+esm1?arch=source&distro=esm-apps/focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.1-2ubuntu0.2+esm1"}]}],"versions":["6.1.1-1","6.2.1-2","6.2.1-2ubuntu0.1~esm1","6.2.1-2ubuntu0.1~esm2","6.2.1-2ubuntu0.1","6.2.1-2ubuntu0.2"],"ecosystem_specific":{"binaries":[{"binary_name":"libvarnishapi2","binary_version":"6.2.1-2ubuntu0.2+esm1"},{"binary_version":"6.2.1-2ubuntu0.2+esm1","binary_name":"varnish"}],"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-45060.json"}},{"package":{"name":"varnish","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/varnish@6.6.1-1ubuntu0.2+esm1?arch=source&distro=esm-apps/jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.1-1ubuntu0.2+esm1"}]}],"versions":["6.5.2-1","6.6.1-1","6.6.1-1ubuntu0.2"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_name":"libvarnishapi2","binary_version":"6.6.1-1ubuntu0.2+esm1"},{"binary_name":"varnish","binary_version":"6.6.1-1ubuntu0.2+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-45060.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}
