libvmod-digest before 1.0.3, as used in Varnish Enterprise 6.0.x before 6.0.11r5, has an out-of-bounds memory access during base64 decoding, leading to both authentication bypass and information disclosure; however, the exact attack surface will depend on the particular VCL (Varnish Configuration Language) configuration in use. • https://docs.varnish-software.com/security/VSV00012 https://github.com/varnish/libvmod-digest/releases/tag/libvmod-digest-1.0.3 https://www.varnish-cache.org/security/VSV00012.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2022-45060
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. Se descubrió un problema de HTTP Request Forgery en Varnish Cache 5.x y 6.x anteriores a 6.0.11, 7.x anteriores a 7.1.2 y 7.2.x anteriores a 7.2.1. • https://docs.varnish-software.com/security/VSV00011 https://lists.debian.org/debian-lts-announce/2022/11/msg00036.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/G6ZMOZVBLZXHEV5VRW4I4SOWLQEK5OF5 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/M4KVVCIQVINQQ2D7ORNARSYALMJUMP3I https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XGF6LFTHXCSYMYUX5HLMVXQH3WHCSFLU https://varnish-cache.org/security/VSV00011.html htt • CWE-918: Server-Side Request Forgery (SSRF) •

In Varnish Cache before 6.6.2 and 7.x before 7.0.2, Varnish Cache 6.0 LTS before 6.0.10, and and Varnish Enterprise (Cache Plus) 4.1.x before 4.1.11r6 and 6.0.x before 6.0.9r4, request smuggling can occur for HTTP/1 connections. En Varnish Cache versiones anteriores a 6.6.2 y 7.x versiones anteriores a 7.0.2, Varnish Cache 6.0 LTS versiones anteriores a 6.0.10, y Varnish Enterprise (Cache Plus) 4.1.x versiones anteriores a 4.1.11r6 y 6.0.x versiones anteriores a 6.0.9r4, puede producirse contrabando de peticiones para conexiones HTTP/1 A flaw was found in Varnish. This flaw allows an attacker to carry out a request smuggling attack on HTTP/1 connections on Varnish cache servers. This smuggled request goes through the usual Varnish Configuration Language (VCL) processing since the Varnish server treats it as an additional request. • https://docs.varnish-software.com/security/VSV00008 https://lists.debian.org/debian-lts-announce/2022/02/msg00014.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UMMDMQWNAE3BTSZUHXQHVAMZC5TLHLYT https://varnish-cache.org/security/VSV00008.html https://www.debian.org/security/2022/dsa-5088 https://access.redhat.com/security/cve/CVE-2022-23959 https://bugzilla.redhat.com/show_bug.cgi?id=2045031 • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

https://notcve.org/view.php?id=CVE-2021-36740
Varnish Cache, with HTTP/2 enabled, allows request smuggling and VCL authorization bypass via a large Content-Length header for a POST request. This affects Varnish Enterprise 6.0.x before 6.0.8r3, and Varnish Cache 5.x and 6.x before 6.5.2, 6.6.x before 6.6.1, and 6.0 LTS before 6.0.8. Varnish Cache, con HTTP/2 habilitado, permite el contrabando de peticiones y la omisión de autorización de VCL por medio de un encabezado Content-Length grande para una petición POST.

https://notcve.org/view.php?id=CVE-2019-20637
An issue was discovered in Varnish Cache before 6.0.5 LTS, 6.1.x and 6.2.x before 6.2.2, and 6.3.x before 6.3.1. It does not clear a pointer between the handling of one client request and the next request within the same connection. This sometimes causes information to be disclosed from the connection workspace, such as data structures associated with previous requests within this connection or VCL-related temporary headers. Se detectó un problema en Varnish Cache versiones anteriores a 6.0.5 LTS, versiones 6.1.x y versiones 6.2.x anteriores a 6.2.2 y versiones 6.3.x anteriores a 6.3.1.
