CWE-1100: Insufficient Isolation of System-Dependent Functions
Learn about CWE-1100 (Insufficient Isolation of System-Dependent Functions), its security impact, exploitation methods, and prevention guidelines.
What is Insufficient Isolation of System-Dependent Functions?
• Overview: Insufficient Isolation of System-Dependent Functions (CWE-1100) occurs when a software product does not separate system-specific operations into distinct, standalone modules. This lack of isolation complicates maintenance and porting efforts, potentially leading to security risks by making it harder to identify and fix vulnerabilities.
• Exploitation Methods:
- Attackers may exploit this vulnerability by targeting system-specific code that is intertwined with application logic, leading to unexpected behavior.
- Common attack patterns include exploiting system-dependent code paths that are not well-understood or documented, increasing the likelihood of unnoticed vulnerabilities.
• Security Impact:
- Direct consequences include increased difficulty in maintaining secure code and a higher likelihood of introducing vulnerabilities during updates.
- Potential cascading effects involve challenges in porting the software to other platforms, which may introduce new security issues.
- Business impact includes increased development and maintenance costs, along with potential reputational damage due to security breaches.
• Prevention Guidelines:
- Specific code-level fixes involve modularizing system-dependent functions and encapsulating them within well-defined interfaces.
- Security best practices include adhering to modular design principles and performing thorough documentation of system-dependent code.
- Recommended tools and frameworks include using platform abstraction layers and employing automated testing tools to identify system-specific dependencies.
