Caddy: MatchPath %xx (escaped-path) branch skips case normalization, enabling path-based route/auth bypass

Caddy is an extensible server platform that uses TLS by default. Prior to version 2.11.1, Caddy's HTTP `path` request matcher is intended to be case-insensitive, but when the match pattern contains percent-escape sequences (`%xx`) it compares against the request's escaped path without lowercasing. An attacker can bypass path-based routing and any access controls attached to that route by changing the casing of the request path. Version 2.11.1 contains a fix for the issue.

Traefik: lowercase `Connection` tokens can delete traefik-managed forwarded identity headers (for example, `X-Real-Ip`)

Traefik is an HTTP reverse proxy and load balancer. From version 2.11.9 to 2.11.37 and from version 3.1.3 to 3.6.8, there is a potential vulnerability in Traefik managing the Connection header with X-Forwarded headers. When Traefik processes HTTP/1.1 requests, the protection put in place to prevent the removal of Traefik-managed X-Forwarded headers (such as X-Real-Ip, X-Forwarded-Host, X-Forwarded-Port, etc.) via the Connection header does not handle case sensitivity correctly. The Connection tokens are compared case-sensitively against the protected header names, but the actual header deletion operates case-insensitively. As a result, a remote unauthenticated client can use lowercase Connection tokens (e.g. Connection: x-real-ip) to bypass the protection and trigger the removal of Traefik-managed forwarded identity headers. This issue has been patched in versions 2.11.38 and 3.6.9.

security flaw

CUPS before 1.1.21rc1 treats a Location directive in cupsd.conf as case sensitive, which allows attackers to bypass intended ACLs via a printer name containing uppercase or lowercase letters that are different from what is specified in the directive.

The default configuration of BEA WebLogic 3.1.8 through 4.5.1 allows a remote attacker to view source code of a JSP program by requesting a URL which provides the JSP extension in upper case.

Netscape FastTrack Web server lists files when a lowercase "get" command is used instead of an uppercase GET.

Unify eWave ServletExec allows a remote attacker to view source code of a JSP program by requesting a URL which provides the JSP extension in upper case.

The file extension check in GNUBoard 3.40 and earlier only verifies extensions that contain all lowercase letters, which allows remote attackers to upload arbitrary files via file extensions that include uppercase letters.

Mbedthis AppWeb HTTP server before 1.1.3 allows remote attackers to bypass access restrictions via a URI with mixed case characters.

Apache on MacOS X Client 10.0.3 with the HFS+ file system allows remote attackers to bypass access restrictions via a URL that contains some characters whose case is not matched by Apache's filters.

Sun ONE Application Server 7.0 for Windows 2000/XP allows remote attackers to obtain JSP source code via a request that uses the uppercase ".JSP" extension instead of the lowercase .jsp extension.

Novell eDirectory 8.6.2 and 8.7 use case insensitive passwords, which makes it easier for remote attackers to conduct brute force password guessing.

Task Manager in Windows 2000 does not allow local users to end processes with uppercase letters named (1) winlogon.exe, (2) csrss.exe, (3) smss.exe and (4) services.exe via the Process tab which could allow local users to install Trojan horses that cannot be stopped with the Task Manager.

jetty: .jsp extension source code disclosure

jetty 6.0.x (jetty6) beta16 allows remote attackers to read arbitrary script source code via a capital P in the .jsp extension, and probably other mixed case manipulations.

Apache for Apple Mac OS X 10.2.8 and 10.3.6 restricts access to files in a case sensitive manner, but the Apple HFS+ filesystem accesses files in a case insensitive manner, which allows remote attackers to read .DS_Store files and files beginning with ".ht" using alternate capitalization.

Perception LiteServe 1.25 allows remote attackers to obtain source code of CGI scripts via URLs that contain MS-DOS conventions such as (1) upper case letters or (2) 8.3 file names.

IBM WebSphere server 3.0.2 allows a remote attacker to view source code of a JSP program by requesting a URL which provides the JSP extension in upper case.

register.php in Ultimate PHP Board (UPB) 1.0 and 1.0b uses an administrative account Admin with a capital "A," but allows a remote attacker to impersonate the administrator by registering an account name of admin with a lower case "a."

Norton Anti-Virus (NAV) allows remote attackers to bypass content filtering via attachments whose Content-Type and Content-Disposition headers are mixed upper and lower case, which is ignored by some mail clients.

simple-git has blockUnsafeOperationsPlugin bypass via case-insensitive protocol.allow config key that enables RCE

`simple-git`, an interface for running git commands in any node.js application, has an issue in versions 3.15.0 through 3.32.2 that allows an attacker to bypass two prior CVE fixes (CVE-2022-25860 and CVE-2022-25912) and achieve full remote code execution on the host machine. Version 3.23.0 contains an updated fix for the vulnerability.

Spring LDAP sensitive data exposure for case-sensitive comparisons

A vulnerability in Spring LDAP allows data exposure for case sensitive comparisons.This issue affects Spring LDAP: from 2.4.0 through 2.4.3, from 3.0.0 through 3.0.9, from 3.1.0 through 3.1.7, from 3.2.0 through 3.2.7, AND all versions prior to 2.4.0. The usage of String.toLowerCase() and String.toUpperCase() has some Locale dependent exceptions that could potentially result in unintended columns from being queried Related to CVE-2024-38820 https://spring.io/security/cve-2024-38820
