Description

Common consequences· 1
- Other / Integrity — Other, Modify Application Data
Potential mitigations· 3
- [Architecture and Design]Use the Thread-Specific Storage Pattern. See References.
- [Implementation]Do not use member fields to store information in the Servlet. In multithreading environments, storing user data in Servlet member fields introduces a data access race condition.
- [Implementation]Avoid using the double-checked locking pattern in language versions that cannot guarantee thread safety. This pattern may be used to avoid the overhead of a synchronized call, but in certain versions of Java (for example), this has been shown to be unsafe because it still introduces a race condition (CWE-209).
