CVSS: 7.5EPSS: 83%CPEs: 444EXPL: 7CVE-2023-44487 – HTTP/2 Rapid Reset Attack Vulnerability
https://notcve.org/view.php?id=CVE-2023-44487
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. El protocolo HTTP/2 permite una denegación de servicio (consumo de recursos del servidor) porque la cancelación de solicitudes puede restablecer muchas transmisiones rápidamente, como se explotó en la naturaleza entre agosto y octubre de 2023. A flaw was found in handling multiplexed streams in the HTTP/2 protocol. A client can repeatedly make a request for a new multiplex stream and immediately send an RST_STREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any server-side limit for the maximum number of active streams per connection, resulting in a denial of service due to server resource consumption. • https://github.com/imabee101/CVE-2023-44487 https://github.com/studiogangster/CVE-2023-44487 https://github.com/bcdannyboy/CVE-2023-44487 https://github.com/sigridou/CVE-2023-44487- https://github.com/ByteHackr/CVE-2023-44487 https://github.com/ReToCode/golang-CVE-2023-44487 http://www.openwall.com/lists/oss-security/2023/10/13/4 http://www.openwall.com/lists/oss-security/2023/10/13/9 http://www.openwall.com/lists/oss-security/2023/10/18/4 http://www. • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.5EPSS: 0%CPEs: 63EXPL: 0CVE-2022-45060 – varnish: Request Forgery Vulnerability
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) •
CVSS: 8.1EPSS: 0%CPEs: 11EXPL: 0CVE-2021-36740 – varnish: HTTP/2 request smuggling attack via a large Content-Length header for a POST request
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. Esto afecta a Varnish Enterprise versiones 6.0.x anteriores a 6.0.8r3, y Varnish Cache versiones 5.xy 6.x anteriores a 6.5.2, versiones 6.6.x anteriores a 6.6.1 y versiones 6.0 LTS anteriores a 6.0.8 A flaw was found in Varnish. The Varnish Cache, with HTTP/2 enabled, allows request smuggling and VCL authorization bypass via a large Content-Length header for a POST request. • https://docs.varnish-software.com/security/VSV00007 https://github.com/varnishcache/varnish-cache/commit/82b0a629f60136e76112c6f2c6372cce77b683be https://github.com/varnishcache/varnish-cache/commit/9be22198e258d0e7a5c41f4291792214a29405cf https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/THV2DQA2GS65HUCKK4KSD2XLN3AAQ2V5 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZHBNLDEOTGYRIEQZBWV7F6VPYS4O2AAK https://varnish-cache.org/security/VSV00007.html https://www.debian.org& • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

CVSS: 7.5EPSS: 0%CPEs: 34EXPL: 0CVE-2017-12425
https://notcve.org/view.php?id=CVE-2017-12425
An issue was discovered in Varnish HTTP Cache 4.0.1 through 4.0.4, 4.1.0 through 4.1.7, 5.0.0, and 5.1.0 through 5.1.2. A wrong if statement in the varnishd source code means that particular invalid requests from the client can trigger an assert, related to an Integer Overflow. This causes the varnishd worker process to abort and restart, losing the cached contents in the process. An attacker can therefore crash the varnishd worker process on demand and effectively keep it from serving content - a Denial-of-Service attack. The specific source-code filename containing the incorrect statement varies across releases. • http://www.debian.org/security/2017/dsa-3924 https://bugzilla.redhat.com/show_bug.cgi?id=1477222 https://bugzilla.suse.com/show_bug.cgi?id=1051917 https://github.com/varnishcache/varnish-cache/issues/2379 https://lists.debian.org/debian-security-announce/2017/msg00186.html https://www.varnish-cache.org/security/VSV00001.html#vsv00001 • CWE-190: Integer Overflow or Wraparound •
