    SV-256611r888324_rule VCPF-70-000001 CCI-000054 MEDIUM Performance Charts must limit the amount of time that each Transport Control Protocol (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-256612r888327_rule VCPF-70-000002 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-256613r888330_rule VCPF-70-000003 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. Limit its size to reduce exposure to a denial-of-service attack. If "maxPostSize" is not set, the default value of 2097152 (
    SV-256614r888333_rule VCPF-70-000004 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 "H
    SV-256615r888336_rule VCPF-70-000005 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-256616r888339_rule VCPF-70-000006 CCI-000169 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-256617r888342_rule VCPF-70-000007 CCI-000162 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-256618r888345_rule VCPF-70-000008 CCI-001749 MEDIUM Performance Charts application files must be verified for their integrity. Verifying 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 the MD5 hash of the RPM original files should be changed after install
    SV-256619r888348_rule VCPF-70-000009 CCI-001749 MEDIUM Performance Charts must only run one webapp. VMware ships Performance Charts on the vCenter Server Appliance (VCSA)with one webapp. Any other path is potentially malicious and must be removed.
    SV-256620r888351_rule VCPF-70-000010 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 vCenter Server Appliance (VCSA) version, Performance Charts may come configured with a "UserDatabaseRealm". This should be removed as part of
    SV-256621r888354_rule VCPF-70-000011 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 properly configured, a Security Exception will be reported if an errant or malicious webapp attempts to access the listed internal classes di
    SV-256622r888357_rule VCPF-70-000012 CCI-000381 MEDIUM Performance Charts must have Multipurpose Internet Mail Extensions (MIMEs) that invoke operating system shell programs disabled. MIME mappings tell 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 various shell script MIME types are not included in "web.xml", the se
    SV-256623r888360_rule VCPF-70-000013 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 identify which file types are not to be delivered to a client. By not specifying which files can an
    SV-256624r888363_rule VCPF-70-000014 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-256625r888366_rule VCPF-70-000015 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, which will lead to "OutOfMemoryErrors" when reloading web applications
    SV-256626r888369_rule VCPF-70-000016 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-256627r888372_rule VCPF-70-000017 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-256628r888375_rule VCPF-70-000018 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-256629r888378_rule VCPF-70-000019 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 could run out of system resources and negatively affect system availability.
    SV-256630r888381_rule VCPF-70-000020 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-256631r888384_rule VCPF-70-000021 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-256632r888387_rule VCPF-70-000022 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 this scenario, the web server will display to the user a list
    SV-256633r888390_rule VCPF-70-000023 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 this scenario, the web server will display to the user a list
    SV-256634r888393_rule VCPF-70-000024 CCI-001312 MEDIUM Performance Charts must be 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-256635r888396_rule VCPF-70-000025 CCI-001312 MEDIUM Performance Charts must be configured to not show error reports. 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-256636r888399_rule VCPF-70-000026 CCI-001312 MEDIUM Performance Charts must hide the server version. 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-256637r888402_rule VCPF-70-000027 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-256638r888405_rule VCPF-70-000028 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-256639r888408_rule VCPF-70-000029 CCI-001849 MEDIUM Performance Charts must properly configure log sizes and rotation. To ensure 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 rotation du
    SV-256640r888411_rule VCPF-70-000030 CCI-001348 MEDIUM Rsyslog must be configured to monitor and ship Performance Charts log files. Performance Charts produces several 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 hosted
    SV-256641r888414_rule VCPF-70-000031 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 Performance Charts listens on are configured in th
    SV-256642r888417_rule VCPF-70-000032 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-256643r888420_rule VCPF-70-000033 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-256644r888423_rule VCPF-70-000034 CCI-000366 MEDIUM Performance Charts default servlet must be set to "readonly". The default servlet (or DefaultServlet) is a special servlet provided with Tomcat that is called when no other suitable page is found in a particular folder. The DefaultServlet serves static resources as well as directory listings. The DefaultServlet is c
