CWE-1105: Insufficient Encapsulation of Machine-Dependent Functionality

What is Insufficient Encapsulation of Machine-Dependent Functionality?

• Overview: Insufficient encapsulation of machine-dependent functionality occurs when code relies on platform-specific features without adequately isolating these dependencies, making the software harder to port and maintain.

• Exploitation Methods:

• Attackers can exploit inconsistencies between platforms to trigger unintended behavior.
• Common attack patterns include exploiting differences in data handling or execution across different environments.

• Security Impact:

• Direct consequences include increased difficulty in identifying and fixing vulnerabilities due to platform-specific dependencies.
• Potential cascading effects could include accidental introduction of vulnerabilities during maintenance or porting efforts.
• Business impact involves increased time and cost for maintaining and porting the software, along with potential downtime or security risks.

• Prevention Guidelines:

• Specific code-level fixes include isolating machine-dependent code in separate modules or using abstraction layers.
• Security best practices involve adhering to cross-platform standards and avoiding platform-specific features where possible.
• Recommended tools and frameworks include using cross-platform development tools that manage machine dependencies automatically.
