{"id":"OESA-2021-1333","summary":"haproxy security update","details":"HAProxy is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications. It is particularly suited for very high traffic web sites and powers quite a number of the world&apos;s most visited ones.\r\n\r\nSecurity Fix(es):\r\n\r\nAn issue was discovered in HAProxy 2.2 before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. It does not ensure that the scheme and path portions of a URI have the expected characters. For example, the authority field (as observed on a target HTTP/2 server) might differ from what the routing rules were intended to achieve.(CVE-2021-39240)\r\n\r\nAn issue was discovered in HAProxy 2.0 before 2.0.24, 2.2 before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. An HTTP method name may contain a space followed by the name of a protected resource. It is possible that a server would interpret this as a request for that protected resource, such as in the &quot;GET /admin? HTTP/1.1 /static/images HTTP/1.1&quot; example.(CVE-2021-39241)\r\n\r\nAn issue was discovered in HAProxy 2.2 before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. It can lead to a situation with an attacker-controlled HTTP Host header, because a mismatch between Host and authority is mishandled.(CVE-2021-39242)","modified":"2025-09-03T06:17:36.112781Z","published":"2021-09-03T11:03:10Z","upstream":["CVE-2021-39240","CVE-2021-39241","CVE-2021-39242"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://openeuler.org/en/security/safety-bulletin/detail.html?id=openEuler-SA-2021-1333"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-39240"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-39241"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-39242"}],"affected":[{"package":{"name":"haproxy","ecosystem":"openEuler:20.03-LTS-SP1","purl":"pkg:rpm/openEuler/haproxy&distro=openEuler-20.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.2.16-1.oe1"}]}],"ecosystem_specific":{"aarch64":["haproxy-debuginfo-2.2.16-1.oe1.aarch64.rpm","haproxy-debugsource-2.2.16-1.oe1.aarch64.rpm","haproxy-2.2.16-1.oe1.aarch64.rpm"],"x86_64":["haproxy-debuginfo-2.2.16-1.oe1.x86_64.rpm","haproxy-debugsource-2.2.16-1.oe1.x86_64.rpm","haproxy-2.2.16-1.oe1.x86_64.rpm"],"src":["haproxy-2.2.16-1.oe1.src.rpm"],"noarch":["haproxy-help-2.2.16-1.oe1.noarch.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2021-1333.json"}},{"package":{"name":"haproxy","ecosystem":"openEuler:20.03-LTS-SP2","purl":"pkg:rpm/openEuler/haproxy&distro=openEuler-20.03-LTS-SP2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.2.16-1.oe1"}]}],"ecosystem_specific":{"aarch64":["haproxy-debuginfo-2.2.16-1.oe1.aarch64.rpm","haproxy-debugsource-2.2.16-1.oe1.aarch64.rpm","haproxy-2.2.16-1.oe1.aarch64.rpm"],"x86_64":["haproxy-2.2.16-1.oe1.x86_64.rpm","haproxy-debugsource-2.2.16-1.oe1.x86_64.rpm","haproxy-debuginfo-2.2.16-1.oe1.x86_64.rpm"],"src":["haproxy-2.2.16-1.oe1.src.rpm"],"noarch":["haproxy-help-2.2.16-1.oe1.noarch.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2021-1333.json"}}],"schema_version":"1.7.3"}
