    SV-239402r674929_rule VCPF-67-000001 CCI-000054 MEDIUM Performance Charts must limit the amount of time that each TCP connection is kept alive. Denial of service (DoS) is one threat against web servers. Many DoS attacks attempt to consume web server resources in such a way that no more resources are available to satisfy legitimate requests. In Tomcat, the "connectionTimeout" attribute sets the
    SV-239403r717041_rule VCPF-67-000002 CCI-000054 MEDIUM Performance Charts must limit the number of concurrent connections permitted. Resource exhaustion can occur when an unlimited number of concurrent requests are allowed on a website, facilitating a denial-of-service attack. Unless the number of requests is controlled, the web server can consume enough system resources to cause a sys
    SV-239404r674935_rule VCPF-67-000003 CCI-000054 MEDIUM Performance Charts must limit the maximum size of a POST request. The "maxPostSize" value is the maximum size in bytes of the POST that will be handled by the container FORM URL parameter parsing. Limiting its size will reduce exposure to a denial-of-service attack. If "maxPostSize" is not set, the default value of 20
    SV-239405r674938_rule VCPF-67-000004 CCI-000054 MEDIUM Performance Charts must protect cookies from cross-site scripting (XSS). Cookies are a common way to save session state over the HTTP(S) protocol. If an attacker can compromise session data stored in a cookie, they are better able to launch an attack against the server and its applications. When a cookie is tagged with the "Ht
    SV-239406r675021_rule VCPF-67-000005 CCI-000067 MEDIUM Performance Charts must record user access in a format that enables monitoring of remote access. Remote access can be exploited by an attacker to compromise the server. By recording all remote access activities, it will be possible to determine the attacker's location, intent, and degree of success. Tomcat can be configured with an "AccessLogValve",
    SV-239407r674944_rule VCPF-67-000006 CCI-000163 MEDIUM Performance Charts must generate log records for system startup and shutdown. Logging must be started as soon as possible when a service starts and when a service is stopped. Many forms of suspicious actions can be detected by analyzing logs for unexpected service starts and stops. Also, by starting to log immediately after a servi
    SV-239408r674947_rule VCPF-67-000007 CCI-000163 MEDIUM Performance Charts log files must only be modifiable by privileged users. Log data is essential in the investigation of events. The accuracy of the information is always pertinent. One of the first steps an attacker will undertake is the modification or deletion of log records to cover tracks and prolong discovery. The web serv
    SV-239409r674950_rule VCPF-67-000008 CCI-001749 MEDIUM Performance Charts application files must be verified for their integrity. Verifying that the Security Token Service application code is unchanged from its shipping state is essential for file validation and nonrepudiation of Performance Charts. There is no reason that the MD5 hash of the rpm original files should be changed aft
    SV-239410r674953_rule VCPF-67-000009 CCI-001749 MEDIUM Performance Charts must only run one web app. VMware ships Performance Charts on the VCSA with one web app. Any other path is potentially malicious and must be removed.
    SV-239411r674956_rule VCPF-67-000010 CCI-000381 MEDIUM Performance Charts must not be configured with unsupported realms. Performance Charts performs user authentication at the application level and not through Tomcat. Depending on the VCSA version, Performance Charts may come configured with a "UserDatabaseRealm". This should be removed as part of eliminating unnecessary fe
    SV-239412r674959_rule VCPF-67-000011 CCI-000381 MEDIUM Performance Charts must have Multipurpose Internet Mail Extensions (MIME) that invoke OS shell programs disabled. MIME mappings tell the Performance Charts what type of program various file types and extensions are and what external utilities or programs are needed to execute the file type. By ensuring that various shell script MIME types are not included in web.xml
    SV-239413r674962_rule VCPF-67-000012 CCI-000381 MEDIUM Performance Charts must have mappings set for Java servlet pages. Resource mapping is the process of tying a particular file type to a process in the web server that can serve that type of file to a requesting client and to identify which file types are not to be delivered to a client. By not specifying which files can
    SV-239414r674965_rule VCPF-67-000013 CCI-000381 MEDIUM Performance Charts must not have the Web Distributed Authoring (WebDAV) servlet installed. WebDAV is an extension to the HTTP protocol that, when developed, was meant to allow users to create, change, and move documents on a server, typically a web server or web share. WebDAV is not widely used and has serious security concerns because it may a
    SV-239415r674968_rule VCPF-67-000014 CCI-000381 MEDIUM Performance Charts must be configured with memory leak protection. The Java Runtime environment can cause a memory leak or lock files under certain conditions. Without memory leak protection, Performance Chart can continue to consume system resources that will lead to "OutOfMemoryErrors" when reloading web applications.
    SV-239416r674971_rule VCPF-67-000015 CCI-000381 MEDIUM Performance Charts must not have any symbolic links in the web content directory tree. A web server is designed to deliver content and execute scripts or applications on the request of a client or user. Containing user requests to files in the directory tree of the hosted web application and limiting the execution of scripts and application
    SV-239417r674974_rule VCPF-67-000016 CCI-001082 MEDIUM Performance Charts directory tree must have permissions in an "out-of-the box" state. Accounts on a web server are to be kept to a minimum. Only administrators, web managers, developers, auditors, and web authors require accounts on the machine hosting the web server. The resources to which these accounts have access must also be closely m
    SV-239418r674977_rule VCPF-67-000017 CCI-001190 MEDIUM Performance Charts must fail to a known safe state if system initialization fails, shutdown fails, or aborts fail. Determining a safe state for failure and weighing that against a potential denial of service for users depends on what type of application the web server is hosting. For Performance Charts, it is preferable that the service abort startup on any initializa
    SV-239419r674980_rule VCPF-67-000018 CCI-001094 MEDIUM Performance Charts must limit the number of allowed connections. Limiting the number of established connections to Performance Charts is a basic denial-of-service protection. Servers where the limit is too high or unlimited can potentially run out of system resources and negatively affect system availability.
    SV-239420r674983_rule VCPF-67-000019 CCI-001310 MEDIUM Performance Charts must set "URIEncoding" to UTF-8. Invalid user input occurs when a user inserts data or characters into a hosted application's data entry field and the hosted application is unprepared to process that data. This results in unanticipated application behavior, potentially leading to an appl
    SV-239421r674986_rule VCPF-67-000020 CCI-001310 MEDIUM Performance Charts must use the "setCharacterEncodingFilter" filter. Invalid user input occurs when a user inserts data or characters into a hosted application's data entry field and the hosted application is unprepared to process that data. This results in unanticipated application behavior, potentially leading to an appl
    SV-239422r674989_rule VCPF-67-000021 CCI-001312 MEDIUM Performance Charts must set the welcome-file node to a default web page. Enumeration techniques, such as URL parameter manipulation, rely on being able to obtain information about the web server's directory structure by locating directories without default pages. In the scenario, the web server will display to the user a listi
    SV-239423r674992_rule VCPF-67-000022 CCI-001312 MEDIUM Performance Charts must not show directory listings. Enumeration techniques, such as URL parameter manipulation, rely on being able to obtain information about the web server's directory structure by locating directories without default pages. In the scenario, the web server will display to the user a listi
    SV-239424r674995_rule VCPF-67-000023 CCI-001312 MEDIUM Performance Charts must configured to show error pages with minimal information. Web servers will often display error messages to client users, including enough information to aid in the debugging of the error. The information given back in error messages may display the web server type, version, patches installed, plug-ins and module
    SV-239425r674998_rule VCPF-67-000024 CCI-001312 MEDIUM Performance Charts must not enable support for TRACE requests. "Trace" is a technique for a user to request internal information about Tomcat. This is useful during product development but should not be enabled in production. Allowing an attacker to conduct a Trace operation against Performance Charts will expose in
    SV-239426r675001_rule VCPF-67-000025 CCI-001312 MEDIUM Performance Charts must have the debug option turned off. Information needed by an attacker to begin looking for possible vulnerabilities in a web server includes any information about the web server and plug-ins or modules being used. When debugging or trace information is enabled in a production web server, in
    SV-239427r675004_rule VCPF-67-000026 CCI-001849 MEDIUM Performance Charts must properly configure log sizes and rotation. To ensure that the logging mechanism used by the web server has sufficient storage capacity in which to write the logs, the logging mechanism must be able to allocate log record storage capacity. Performance Charts properly sizes and configures log rotati
    SV-239428r675007_rule VCPF-67-000027 CCI-001348 MEDIUM Rsyslog must be configured to monitor and ship Performance Charts log files. Performance Charts produces a handful of logs that must be offloaded from the originating system. This information can then be used for diagnostic purposes, forensics purposes, or other purposes relevant to ensuring the availability and integrity of the h
    SV-239429r675010_rule VCPF-67-000028 CCI-001762 MEDIUM Performance Charts must be configured with the appropriate ports. Web servers provide numerous processes, features, and functionalities that use TCP/IP ports. Some of these processes may be deemed unnecessary or too unsecure to run on a production system. The ports that the Performance Charts listens on are configured i
    SV-239430r675013_rule VCPF-67-000029 CCI-002385 MEDIUM Performance Charts must disable the shutdown port. An attacker has at least two reasons to stop a web server. The first is to cause a denial of service, and the second is to put in place changes the attacker made to the web server configuration. If the Tomcat shutdown port feature is enabled, a shutdown
    SV-239431r675016_rule VCPF-67-000030 CCI-002418 MEDIUM Performance Charts must set the secure flag for cookies. The secure flag is an option that can be set by the application server when sending a new cookie to the user within an HTTP Response. The purpose of the secure flag is to prevent cookies from being observed by unauthorized parties due to the transmission
    SV-239432r675019_rule VCPF-67-000031 CCI-000381 MEDIUM Performance Charts must be configured to limit access to internal packages. The "package.access" entry in the "catalina.properties" file implements access control at the package level. When this is properly configured, a Security Exception will be reported if an errant or malicious web app attempts to access the listed internal c
