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.

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.

Cross-site scripting (XSS) vulnerability in memcache_admin in the Memcache module 5.x before 5.x-1.10 and 6.x before 6.x-1.6 for Drupal allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

The Memcache module 5.x before 5.x-1.10 and 6.x before 6.x-1.6 for Drupal does not properly handle the $user object in memcache_admin, which might "lead to a role change not being recognized until the user logs in again."

Multiple cross-site scripting (XSS) vulnerabilities in the ImageCache module 5.x before 5.x-2.5 and 6.x before 6.x-2.0-beta10, a module for Drupal, allow remote authenticated users, with "administer imagecache" permissions, to inject arbitrary web script or HTML via unspecified vectors.

The ImageCache module 5.x before 5.x-2.5 and 6.x before 6.x-2.0-beta10, a module for Drupal, when the private file system is used, does not properly perform access control for derivative images, which allows remote attackers to view arbitrary images via a request that specifies an image's filename.

Unspecified vulnerability in the %XML.Utils.SchemaServer class in InterSystems Cache' 5.0 allows attackers to access arbitrary files on a server.

Unspecified vulnerability in the %template package in InterSystems Cache' 5.0 allows attackers to access certain files on a server, including (1) cache.key and (2) cache.dat, related to .csp files under (a) Dev\studio\templates and (b) Devuser\studio\templates.

Unknown vulnerability in Network Appliance NetCache 5.2 and Data ONTAP 6.0 allows remote attackers to cause a denial of service (panic and reboot) and possibly other impacts via unknown attack vectors, possibly related to unspecified worms, as identified by bug ID

Unspecified vulnerability in the Cache' Server Page (CSP) implementation in InterSystems Cache' 4.0.3 through 5.0.5 allows remote attackers to "gain complete control" of a server.
