CWE-9: J2EE Misconfiguration: Weak Access Permissions for EJB Methods
Learn about CWE-9 (J2EE Misconfiguration: Weak Access Permissions for EJB Methods), its security impact, exploitation methods, and prevention guidelines.
What is J2EE Misconfiguration: Weak Access Permissions for EJB Methods?
• Overview: J2EE Misconfiguration: Weak Access Permissions for EJB Methods occurs when EJB methods are assigned elevated access rights, allowing unauthorized users potentially dangerous levels of access to application functions.
• Exploitation Methods:
- Attackers can exploit this vulnerability by identifying EJB methods with weak permissions and using them to perform unauthorized actions.
- Common attack patterns include probing for EJB methods accessible to the public and using them to escalate privileges or execute unauthorized transactions.
• Security Impact:
- Direct consequences of successful exploitation include unauthorized access to sensitive data and operations within the application.
- Potential cascading effects could involve further penetration into the system, leading to more significant data breaches or system compromises.
- Business impact includes loss of customer trust, potential legal penalties, and financial losses due to data breaches.
• Prevention Guidelines:
- Specific code-level fixes involve reviewing EJB deployment descriptors and ensuring that only necessary roles have access to critical methods.
- Security best practices include implementing the principle of least privilege, ensuring that EJB methods are only accessible to roles that absolutely require access.
- Recommended tools and frameworks include security-focused code review tools and frameworks that support role-based access control (RBAC) configurations.
