CWE-1097: Persistent Storable Data Element without Associated Comparison Control Element
Learn about CWE-1097 (Persistent Storable Data Element without Associated Comparison Control Element), its security impact, exploitation methods, and prevention guidelines.
What is Persistent Storable Data Element without Associated Comparison Control Element?
• Overview: This vulnerability occurs when a storable data element, such as a class in Java, lacks the necessary methods for proper comparison, like hashCode() and equals(). This can lead to unreliable program behavior and potentially introduce security risks if the code is accessible by an attacker.
• Exploitation Methods:
- Attackers can exploit this by creating or manipulating data elements that rely on comparison for functioning, potentially leading to incorrect program execution.
- Common attack patterns include data tampering or insertion of crafted objects that exploit the absence of these comparison methods.
• Security Impact:
- Direct consequences include application crashes, data corruption, or logic errors due to improper handling of comparisons.
- Potential cascading effects involve broader system instability or unreliable data manipulation.
- Business impact could include loss of data integrity, reduced system availability, and potential breaches of sensitive information.
• Prevention Guidelines:
- Specific code-level fixes involve implementing and thoroughly testing both hashCode() and equals() methods for any persistent classes.
- Security best practices include regular code reviews and automated testing to ensure all necessary methods are present and correctly implemented.
- Recommended tools and frameworks include static analysis tools that can detect missing method implementations and provide guidance on correct implementation practices.
