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 number of milliseconds the server will wait after accepting a connection for the request URI line to be presented. This timeout will also be used when reading the request body (if any). This prevents idle sockets that are not sending HTTP requests from consuming system resources and potentially denying new connections.
Checks: C-42635r674927_chk

At the command prompt, execute the following command: # xmllint --xpath '/Server/Service/Connector/@connectionTimeout' /usr/lib/vmware-perfcharts/tc-instance/conf/server.xml Expected result: connectionTimeout="20000" If the output does not match the expected result, this is a finding.

Fix: F-42594r674928_fix

Navigate to and open /usr/lib/vmware-perfcharts/tc-instance/conf/server.xml. Navigate to each of the <Connector> nodes. Configure each <Connector> node with the value: connectionTimeout="20000"

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 system crash. Mitigating this kind of attack will include limiting the number of concurrent HTTP/HTTPS requests. In Tomcat, each incoming request requires a thread for the duration of that request. If more simultaneous requests are received than can be handled by the currently available request processing threads, additional threads will be created up to the value of the "maxThreads" attribute.
Checks: C-42636r674930_chk

At the command prompt, execute the following command: # xmllint --xpath '/Server/Service/Executor/@maxThreads' /usr/lib/vmware-perfcharts/tc-instance/conf/server.xml Expected result: maxThreads="300" If the output does not match the expected result, this is a finding.

Fix: F-42595r674931_fix

Navigate to and open /usr/lib/vmware-perfcharts/tc-instance/conf/server.xml. Navigate to the <Executor> mode with the name of "tomcatThreadPool" and configure with the value 'maxThreads="300"'. Note: The <Executor> node should be configured as follows: <Executor maxThreads="300" minSpareThreads="50" name="tomcatThreadPool" namePrefix="tomcat-http--"/>

b

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 2097152 (2MB) is used. Performance Charts is configured in its shipping state to not set a value for "maxPostSize".
Checks: C-42637r674933_chk

At the command prompt, execute the following command: # xmllint --xpath '/Server/Service/Connector/@maxPostSize' /usr/lib/vmware-perfcharts/tc-instance/conf/server.xml Expected result: XPath set is empty If the output does not match the expected result, this is a finding.

Fix: F-42596r674934_fix

Navigate to and open /usr/lib/vmware-perfcharts/tc-instance/conf/server.xml. Navigate to each of the <Connector> nodes. Remove any configuration for "maxPostSize".

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 "HttpOnly" flag, it tells the browser that this particular cookie should only be accessed by the originating server. Any attempt to access the cookie from client script is strictly forbidden. Satisfies: SRG-APP-000001-WSR-000002, SRG-APP-000439-WSR-000154
Checks: C-42638r674936_chk

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", a component that can be inserted into the request processing pipeline to provide robust access logging. The AccessLogValve creates log files in the same format as those created by standard web servers. When AccessLogValve is properly configured, log files will contain all the forensic information necessary in the case of a security incident. Satisfies: SRG-APP-000016-WSR-000005, SRG-APP-000095-WSR-000056, SRG-APP-000096-WSR-000057, SRG-APP-000097-WSR-000058, SRG-APP-000098-WSR-000059, SRG-APP-000098-WSR-000060, SRG-APP-000099-WSR-000061, SRG-APP-000100-WSR-000064, SRG-APP-000374-WSR-000172, SRG-APP-000375-WSR-000171

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 service starts, it becomes more difficult for suspicious activity to go unlogged. On the VCSA, the "vmware-vmon" service starts up the Java virtual machines (JVMs) for various vCenter processes, including Performance Charts, and the individual "json" config files control the early JVM logging. Ensuring these "json" files are configured correctly enables early Java "stdout" and "stderr" logging. Satisfies: SRG-APP-000089-WSR-000047, SRG-APP-000092-WSR-000055
Checks: C-42640r674942_chk

At the command prompt, execute the following command: # grep StreamRedirectFile /etc/vmware/vmware-vmon/svcCfgfiles/perfcharts.json Expected result: "StreamRedirectFile" : "%VMWARE_LOG_DIR%/vmware/perfcharts/vmware-perfcharts-runtime.log", If the output does not match the expected result, this is a finding.

Fix: F-42599r674943_fix

Navigate to and open /etc/vmware/vmware-vmon/svcCfgfiles/perfcharts.json. Below the last line of the "PreStartCommandArg" block, add the following line: "StreamRedirectFile" : "%VMWARE_LOG_DIR%/vmware/perfcharts/vmware-perfcharts-runtime.log", Restart the appliance for changes to take effect.

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 server must protect the log data from unauthorized modification. Performance Charts restricts all modification of log files by default, but this configuration must be verified. Satisfies: SRG-APP-000119-WSR-000069, SRG-APP-000120-WSR-000070

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 and cannot be served to a user, the web server could deliver to a user web server configuration files, log files, password files, etc. Because Tomcat is a Java-based web server, the main file extension used is *.jsp. This check ensures that the *.jsp and *.jspx file types have been properly mapped to servlets.

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 allow clients to modify unauthorized files on the web server and must therefore be disabled. Tomcat uses the "org.apache.catalina.servlets.WebdavServlet" servlet to provide WebDAV services. Because the WebDAV service has been found to have an excessive number of vulnerabilities, this servlet must not be installed. Performance Charts does not configure WebDAV by default.
Checks: C-42647r674963_chk

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. Memory leaks occur when JRE code uses the context class loader to load a singleton. This will cause a memory leak if a web application class loader happens to be the context class loader at the time. The "JreMemoryLeakPreventionListener" class is designed to initialize these singletons when Tomcat's common class loader is the context class loader. Proper use of JRE memory leak protection will ensure that the hosted application does not consume system resources and cause an unstable environment.

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 application compromise. Invalid user input is one of the primary methods employed when attempting to compromise an application. An attacker can also enter Unicode characters into hosted applications in an effort to break out of the document home or root home directory or to bypass security checks. Performance Charts must be configured to use a consistent character set via the "URIEncoding" attribute on the Connector nodes.

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 listing of the files in the directory being accessed. By having a default hosted application web page, the anonymous web user will not obtain directory browsing information or an error message that reveals the server type and version. Ensuring that every document directory has an "index.jsp" (or equivalent) file is one approach to mitigating the vulnerability.

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 modules installed, type of code being used by the hosted application, and any backends being used for data storage. This information could be used by an attacker to blueprint what type of attacks might be successful. Therefore, Performance Charts must be configured with a catch-all error handler that redirects to a standard "error.jsp".

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, information about the web server, such as web server type, version, patches installed, plug-ins and modules installed, type of code being used by the hosted application, and any backends being used for data storage may be displayed. Because this information may be placed in logs and general messages during normal operation of the web server, an attacker does not need to cause an error condition to gain this information. The Performance Charts Service can be configured to set the debugging level. By setting the debugging level to zero, no debugging information will be provided to a malicious user.

Security flaws with software applications are discovered daily. Vendors are constantly updating and patching their products to address newly discovered security vulnerabilities. Organizations (including any contractor to the organization) are required to promptly install security-relevant software updates (e.g., patches, service packs, and hot fixes). Flaws discovered during security assessments, continuous monitoring, incident response activities, or information system error handling must also be addressed expeditiously. Organization-defined time periods for updating security-relevant software may vary based on a variety of factors including, for example, the security category of the information system or the criticality of the update (i.e., severity of the vulnerability related to the discovered flaw). This requirement will apply to software patch management solutions that are used to install patches across the enclave and to applications that are not part of that patch management solution. For example, many browsers today provide the capability to install their own patch software. Patch criticality, as well as system criticality, will vary. Therefore, the tactical situations regarding the patch management process will also vary. This means the time period used must be a configurable parameter. Time frames for application of security-relevant software updates may be dependent upon the Information Assurance Vulnerability Management (IAVM) process. The application will be configured to check for and install security-relevant software updates within an identified time period from the availability of the update. The specific time period will be defined by an authoritative source (e.g., IAVM, CTOs, DTMs, and STIGs).
