A default configuration of Apache on Debian GNU/Linux sets the ServerRoot to /usr/doc, which allows remote users to read documentation files for the entire server.

The Apache web server for Win32 may provide access to restricted files when a . (dot) is appended to a requested URL.

ScriptAlias directory in NCSA and Apache httpd allowed attackers to read CGI programs.

The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.12 does not have the expected countermeasures against replay attacks, which makes it easier for remote attackers to bypass intended access restrictions by sniffing the network for valid requests, related to lack of checking of nonce (aka server nonce) and nc (aka nonce-count or client nonce count) values.

The HTTP BIO connector in Apache Tomcat 7.0.x before 7.0.12 does not properly handle HTTP pipelining, which allows remote attackers to read responses intended for other clients in opportunistic circumstances by examining the application data in HTTP packets, related to "a mix-up of responses for requests from different users."

In Apache Tapestry from 5.4.0 to 5.5.0, crafting specific URLs, an attacker can download files inside the WEB-INF folder of the WAR being run.

Apache Camel's JMX is vulnerable to Rebind Flaw. Apache Camel 2.22.x, 2.23.x, 2.24.x, 2.25.x, 3.0.0 up to 3.1.0 is affected. Users should upgrade to 3.2.0.

Server-Side Template Injection and arbitrary file disclosure on Camel templating components

In Apache Kylin, Cross-origin requests with credentials are allowed to be sent from any origin. This issue affects Apache Kylin 2 version 2.6.6 and prior versions; Apache Kylin 3 version 3.1.2 and prior versions; Apache Kylin 4 version 4.0.0 and prior versions.

Apache Kylin provides encryption classes PasswordPlaceholderConfigurer to help users encrypt their passwords. In the encryption algorithm used by this encryption class, the cipher is initialized with a hardcoded key and IV. If users use class PasswordPlaceholderConfigurer to encrypt their password and configure it into kylin's configuration file, there is a risk that the password may be decrypted. This issue affects Apache Kylin 2 version 2.6.6 and prior versions; Apache Kylin 3 version 3.1.2 and prior versions; Apache Kylin 4 version 4.0.0 and prior versions.

Apache Shiro before 1.1.0, and JSecurity 0.9.x, does not canonicalize URI paths before comparing them to entries in the shiro.ini file, which allows remote attackers to bypass intended access restrictions via a crafted request, as demonstrated by the /./account/index.jsp URI.

The Jetty ResourceHandler in Apache ActiveMQ 5.x before 5.3.2 and 5.4.x before 5.4.0 allows remote attackers to read JSP source code via a // (slash slash) initial substring in a URI for (1) admin/index.jsp, (2) admin/queues.jsp, or (3) admin/topics.jsp.

The ap_log_rerror function in Apache 2.0 through 2.035, when a CGI application encounters an error, sends error messages to the client that include the full path for the server, which allows remote attackers to obtain sensitive information.

Apache Atlas versions 0.6.0 (incubating), 0.7.0 (incubating), and 0.7.1 (incubating) allow access to the webapp directory contents by pointing to URIs like /js and /img.

Product: Apache Cordova Android 5.2.2 and earlier. The application calls methods of the Log class. Messages passed to these methods (Log.v(), Log.d(), Log.i(), Log.w(), and Log.e()) are stored in a series of circular buffers on the device. By default, a maximum of four 16 KB rotated logs are kept in addition to the current log. The logged data can be read using Logcat on the device. When using platforms prior to Android 4.1 (Jelly Bean), the log data is not sandboxed per application; any application installed on the device has the capability to read data logged by other applications.

The ResourceLinkFactory implementation in Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 did not limit web application access to global JNDI resources to those resources explicitly linked to the web application. Therefore, it was possible for a web application to access any global JNDI resource whether an explicit ResourceLink had been configured or not.

When a SecurityManager is configured, a web application's ability to read system properties should be controlled by the SecurityManager. In Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70, 6.0.0 to 6.0.45 the system property replacement feature for configuration files could be used by a malicious web application to bypass the SecurityManager and read system properties that should not be visible.

Apache Cordova-Android before 3.7.0 improperly generates random values for BridgeSecret data, which makes it easier for attackers to conduct bridge hijacking attacks by predicting a value.

Multiple directory traversal vulnerabilities in Apache Struts 2.0.x before 2.0.12 and 2.1.x before 2.1.3 allow remote attackers to read arbitrary files via a ..%252f (encoded dot dot slash) in a URI with a /struts/ path, related to (1) FilterDispatcher in 2.0.x and (2) DefaultStaticContentLoader in 2.1.x.

Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, 6.0.0 through 6.0.18, and possibly earlier versions normalizes the target pathname before filtering the query string when using the RequestDispatcher method, which allows remote attackers to bypass intended access restrictions and conduct directory traversal attacks via .. (dot dot) sequences and the WEB-INF directory in a Request.

In Apache HTTP Server versions 2.4.0 to 2.4.23, mod_session_crypto was encrypting its data/cookie using the configured ciphers with possibly either CBC or ECB modes of operation (AES256-CBC by default), hence no selectable or builtin authenticated encryption. This made it vulnerable to padding oracle attacks, particularly with CBC.

Apache Kylin 2.0.0, 2.1.0, 2.2.0, 2.3.0, 2.3.1, 2.3.2, 2.4.0, 2.4.1, 2.5.0, 2.5.1, 2.5.2, 2.6.0, 2.6.1, 2.6.2, 2.6.3, 2.6.4, 2.6.5, 2.6.6, 3.0.0-alpha, 3.0.0-alpha2, 3.0.0-beta, 3.0.0, 3.0.1, 3.0.2, 3.1.0, 4.0.0-alpha has one restful api which exposed Kylin's configuration information without any authentication, so it is dangerous because some confidential information entries will be disclosed to everyone.

Apache Tomcat 4.1.0 through 4.1.37, 5.5.0 through 5.5.26, and 6.0.0 through 6.0.16, when a RequestDispatcher is used, performs path normalization before removing the query string from the URI, which allows remote attackers to conduct directory traversal attacks and read arbitrary files via a .. (dot dot) in a request parameter.

The uri-block plugin in Apache APISIX before 2.10.2 uses $request_uri without verification. The $request_uri 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 "^/internal/", a URI like `//internal/` can be used to bypass it. Some other plugins also have the same issue. And it may affect the developer's custom plugin.

Apache Tomcat 5 before 5.5.17 allows remote attackers to list directories via a semicolon (;) preceding a filename with a mapped extension, as demonstrated by URLs ending with /;index.jsp and /;help.do.

The default installation of Apache Tomcat 4.0 through 4.1 and 3.0 through 3.3.1 allows remote attackers to obtain the installation path and other sensitive system information via the (1) SnoopServlet or (2) TroubleShooter example servlets.

The Mapper component in Apache Tomcat 6.x before 6.0.45, 7.x before 7.0.68, 8.x before 8.0.30, and 9.x before 9.0.0.M2 processes redirects before considering security constraints and Filters, which allows remote attackers to determine the existence of a directory via a URL that lacks a trailing / (slash) character.

Apache Tomcat 4.0.3, when running on Windows, allows remote attackers to obtain sensitive information via a request for a file that contains an MS-DOS device name such as lpt9, which leaks the pathname in an error message, as demonstrated by lpt9.xtp using Nikto.

The SingleSignOn Valve (org.apache.catalina.authenticator.SingleSignOn) in Apache Tomcat before 5.5.21 does not set the secure flag for the JSESSIONIDSSO cookie in an https session, which can cause the cookie to be sent in http requests and make it easier for remote attackers to capture this cookie.

Apache Tomcat 4.0.3 for Windows allows remote attackers to obtain the web root path via an HTTP request for a resource that does not exist, such as lpt9, which leaks the information in an error message.

mod_python (libapache2-mod-python) 3.1.4 and earlier does not properly handle when output filters process more than 16384 bytes, which can cause filter.read to return portions of previously freed memory.

Directory traversal vulnerability in the view-source sample file in Apache Software Foundation Cocoon 2.1 and 2.2 allows remote attackers to access arbitrary files via a .. (dot dot) in the filename parameter.

Unspecified vulnerability in the management EJB (MEJB) in Apache Geronimo before 2.0.2 allows remote attackers to bypass authentication and obtain "access to Geronimo internals" via unspecified vectors.

Jakarta Tomcat before 3.3.1a, when used with JDK 1.3.1 or earlier, allows remote attackers to list directories even with an index.html or other file present, or obtain unprocessed source code for a JSP file, via a URL containing a null character.

Jakarta Tomcat before 3.3.1a, when used with JDK 1.3.1 or earlier, uses trusted privileges when processing the web.xml file, which could allow remote attackers to read portions of some files through the web.xml file.

The default servlet (org.apache.catalina.servlets.DefaultServlet) in Tomcat 4.0.4 and 4.1.10 and earlier allows remote attackers to read source code for server files via a direct request to the servlet.

Apache 2.0.42 allows remote attackers to view the source code of a CGI script via a POST request to a directory with both WebDAV and CGI enabled.

Apache 2.0 through 2.0.39 on Windows, OS2, and Netware allows remote attackers to determine the full pathname of the server via (1) a request for a .var file, which leaks the pathname in the resulting error message, or (2) via an error message that occurs when a script (child process) cannot be invoked.

PHP, when installed with Apache and configured to search for index.php as a default web page, allows remote attackers to obtain the full pathname of the server via the HTTP OPTIONS method, which reveals the pathname in the resulting error message.

Apache Software Foundation Tomcat Servlet prior to 3.2.2 allows a remote attacker to read the source code to arbitrary 'jsp' files via a malformed URL request which does not end with an HTTP protocol specification (i.e. HTTP/1.0).

The default installation of Apache before 1.3.19 allows remote attackers to list directories instead of the multiview index.html file via an HTTP request for a path that contains many / (slash) characters, which causes the path to be mishandled by (1) mod_negotiation, (2) mod_dir, or (3) mod_autoindex.

Jakarta Tomcat 4.0.1 allows remote attackers to reveal physical path information by requesting a long URL with a .JSP extension.

Directory traversal vulnerability in source.jsp of Apache Tomcat before 3.1 allows remote attackers to read arbitrary files via a .. (dot dot) in the argument to source.jsp.

mod_rewrite in Apache 1.3.12 and earlier allows remote attackers to read arbitrary files if a RewriteRule directive is expanded to include a filename whose name contains a regular expression.

Vulnerability in Apache httpd before 1.3.11, when configured for mass virtual hosting using mod_rewrite, or mod_vhost_alias in Apache 1.3.9, allows remote attackers to retrieve arbitrary files.

The default configuration of Apache 1.3.12 in SuSE Linux 6.4 enables WebDAV, which allows remote attackers to list arbitrary directories via the PROPFIND HTTP request method.

In Apache RocketMQ 4.2.0 to 4.6.0, when the automatic topic creation in the broker is turned on by default, an evil topic like “../../../../topic2020” is sent from rocketmq-client to the broker, a topic folder will be created in the parent directory in brokers, which leads to a directory traversal vulnerability. Users of the affected versions should apply one of the following: Upgrade to Apache RocketMQ 4.6.1 or later.

PHP 3.x (PHP3) on Apache 1.3.6 allows remote attackers to read arbitrary files via a modified .. (dot dot) attack containing "%5c" (encoded backslash) sequences.
