Vuln_Discuss Encryption is critical for protection of web-based traffic. If encryption is not being used to protect the application server's web connectors, malicious users may gain the ability to read or modify the application traffic while it is in transit over the network. The use of cryptography on web connectors secures web-based traffic and mitigates that risk. HTTPS and Transport Layer Security (TLS) are the means in which cryptographic protections are applied to web connectors. FIPS 140-2 approved TLS versions include TLS V1.2 or greater.

Vuln_Discuss The Java Security Manager is a java class that manages the external boundary of the Java Virtual Machine (JVM) sandbox, controlling how code executing within the JVM can interact with resources outside the JVM. The JVM requires a security policy in order to restrict application access. A properly configured security policy will define what rights the application has to the underlying system. For example, rights to make changes to files on the host system or to initiate network sockets in order to connect to another system. Check_Content Enabling the Security Manager in JDK 24 is an error and if using JDK 24, this is not a finding. Note: Security Manager was deprecated in Java 17 and will be permanently removed in JDK 24. For additional information: <https://openjdk.org/jeps/486> Obtain documentation from the admin that identifies the applications hosted on the JBoss server as well as the corresponding rights the application requires. For example, if the application requires network socket permissions and file write permissions, document those requirements. 1. Identify the JBoss installation as either domain or standalone and review the relevant configuration file. For domain installs: JBOSS_HOME/bin/domain.conf For standalone installs: JBOSS_HOME/bin/standalone.conf 2. Identify the location and name of the security policy by reading the JAVA_OPTS flag -Djava.security.policy=<file name> where <file name> will indicate name and location of security policy. If the application uses a policy URL, obtain the URL and policy file from system admin. 3. Review security policy and ensure hosted applications have the appropriate restrictions placed on them per documented application functionality requirements. If the security policy does not restrict application access to host resources per documented requirements, this is a finding.

Vuln_Discuss The Java Security Manager is a java class that manages the external boundary of the Java Virtual Machine (JVM) sandbox, controlling how code executing within the JVM can interact with resources outside the JVM. The Java Security Manager uses a security policy to determine whether a given action will be permitted or denied. To protect the host system, the JBoss application server must be run within the Java Security Manager. Check_Content Enabling the Security Manager in JDK 24 is an error and if using JDK 24, this is not a finding. Note, Security Manager was deprecated in Java 17 and will be permanently removed in JDK 24. For additional information: <https://openjdk.org/jeps/486> To determine if the Java Security Manager is enabled for JBoss, the startup commands must be examined. JBoss can be configured to run in either "domain" or a "standalone" mode. JBOSS_HOME is the variable home directory for the JBoss installation. Use relevant OS commands to navigate the file system. 1. For a managed domain installation, review the domain.conf and domain.conf.bat files: JBOSS_HOME/bin/domain.conf JBOSS_HOME/bin/domain.conf.bat In domain.conf file, ensure there is a JAVA_OPTS flag that loads the Java Security Manager as well as a relevant Java Security policy. Example: JAVA_OPTS="$JAVA_OPTS -Djava.security.manager -Djava.security.policy==$PWD/server.policy -Djboss.home.dir=/path/to/JBOSS_HOME -Djboss.modules.policy-permissions=true" In domain.conf.bat file, ensure JAVA_OPTS flag is set.

By default, the ROOT logger level is set to INFO, which is a value of 800. This will capture most events adequately. Any level numerically higher than INFO (> 800) records less data and may result in an insufficient amount of information being logged by the ROOT logger.

If one factor is compromised or broken, the attacker still has at least one more barrier to breach before successfully breaking into the target. Unlike a simple username/password scenario where the attacker could gain access by knowing both the username and password without the user knowing his account was compromised, multifactor authentication adds the requirement that the attacker must have something from the user, such as a token, or to biometrically be the user. Multifactor authentication is defined as: using two or more factors to achieve authentication. Factors include: (i) something a user knows (e.g., password/PIN); (ii) something a user has (e.g., cryptographic identification device, token); or (iii) something a user is (e.g., biometric). A CAC or PKI Hardware Token meets this definition. A privileged account is defined as an information system account with authorizations of a privileged user.

Vuln_Discuss The cornerstone of the PKI is the private key used to encrypt or digitally sign information. If the private key is stolen, this will lead to the compromise of the authentication and non-repudiation gained through PKI because the attacker can use the private key to digitally sign documents and can pretend to be the authorized user. Both the holders of a digital certificate and the issuing authority must protect the computers, storage devices, or whatever they use to keep the private keys.

By separating the management interface from hosted applications, the user must authenticate as a privileged user to the management interface before being presented with management functionality. This prevents non-privileged users from having visibility to functions not available to the user. By limiting visibility, a compromised non-privileged account does not offer information to the attacker or functionality and information needed to further the attack on the application server. JBoss is designed to operate with separate application and management interfaces. The JBoss server is started via a script. To start the JBoss server in domain mode, the admin will execute the <JBOSS_HOME>/bin/domain.sh or domain.bat script.

The structure and content of error messages need to be carefully considered by the organization and development team. The extent to which the information system is able to identify and handle error conditions is guided by organizational policy and operational requirements. Application servers must protect the error messages that are created by the application server. All application server users' accounts are used for the management of the server and the applications residing on the application server. All accounts are assigned to a certain role with corresponding access rights. The application server must restrict access to error messages so only authorized users may view them.

Vuln_Discuss Determining when a user has accessed the management interface is important to determine the timeline of events when a security incident occurs. Generating these events, especially if the management interface is accessed via a stateless protocol like HTTP, the log events will be generated when the user performs a logon (start) and when the user performs a logoff (end). Without these events, the user and later investigators cannot determine the sequence of events and therefore cannot determine what may have happened and by whom it may have been done. The generation of start and end times within log events allows the user to perform their due diligence in the event of a security breach.

When concurrent logons are made from different workstations to the management interface, a log record needs to be generated. This configuration setting provides forensic evidence that allows the system administrator to investigate access to the system and determine if the duplicate access was authorized or not.

Vuln_Discuss The maintenance of user accounts is a key activity within the system to determine access and privileges. Through changes to accounts, an attacker can create an account for persistent access, modify an account to elevate privileges, or terminate/disable an account(s) to cause a DoS for user(s). To be able to track and investigate these actions, log records must be generated for any account modification functions.

Vuln_Discuss Class 3 PKI certificates are used for servers and software signing rather than for identifying individuals. Class 4 certificates are used for business-to-business transactions. Utilizing unapproved certificates not issued or approved by DoD or CNS creates an integrity risk. The application server must utilize approved DoD or CNS Class 3 or Class 4 certificates for software signing and business-to-business transactions. Check_Content Interview the administrator to determine if JBoss is using certificates for PKI. If JBoss is not performing any PKI functions, this finding is NA. The CA certs are usually stored in a file called cacerts located in the directory $JAVA_HOME/lib/security. If the file is not in this location, use a search command to locate the file, or ask the administrator where the certificate store is located. Open a dos shell or terminal window and change to the location of the certificate store. To view the certificates within the certificate store, run the command (in this example, the keystore file is cacerts.): keytool -list -v -keystore ./cacerts Locate the "OU" field for each certificate within the keystore.

Vuln_Discuss JBoss provides multiple interfaces for accessing the system. By default, these are called "public" and "management". Allowing non-management traffic to access the JBoss management interface increases the chances of a security compromise. The JBoss server must be configured to bind the management interface to a network that controls access. This is usually a network that has been designated as a management network and has restricted access. Similarly, the public interface must be bound to a network that is not on the same segment as the management interface. Check_Content Obtain documentation and network drawings from system admin that shows the network interfaces on the JBoss server and the networks they are configured for.
