BIT-ENVOY-2021-29492 Bypass of path matching rules using escaped slash characters

Envoy is a cloud-native edge/middle/service proxy. Envoy does not decode escaped slash sequences %2F and %5C in HTTP URL paths in versions 1.18.2 and before. A remote attacker may craft a path with escaped slashes, e.g. /something%2F..%2Fadmin, to bypass access control, e.g. a block on /admin. A...

Envoy is an open source L7 proxy and communication bus designed for large modern service oriented architectures. In affected versions envoy incorrectly handled a URI 'fragment' element as part of the path element. Envoy is configured with an RBAC filter for authorization or similar mechanism with...

BIT-MASTODON-2023-42451 Mastodon Invalid Domain Name Normalization vulnerability

Mastodon is a free, open-source social network server based on ActivityPub. Prior to versions 3.5.14, 4.0.10, 4.1.8, and 4.2.0, under certain circumstances, attackers can exploit a flaw in domain name normalization to spoof domains they do not own. Versions 3.5.14, 4.0.10, 4.1.8, and 4.2.0 contai...

BIT-APISIX-2021-43557 Path traversal in request_uri variable

The uri-block plugin in Apache APISIX before 2.10.2 uses $requesturi without verification. The $requesturi is the full original request URI without normalization. This makes it possible to construct a URI to bypass the block list on some occasions. For instance, when the block list contains...

BIT-DJANGO-2023-46695

An issue was discovered in Django 3.2 before 3.2.23, 4.1 before 4.1.13, and 4.2 before 4.2.7. The NFKC normalization is slow on Windows. As a consequence, django.contrib.auth.forms.UsernameField is subject to a potential DoS denial of service attack via certain inputs with a very large number of...
