Official CWE-383 CWE context with Glexia analysis, remediation guidance, related CVEs, and ATT&CK context.
Glexia's Take
CWE-383: J2EE Bad Practices: Direct Use of Threads
J2EE Bad Practices: Direct Use of Threads represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
Executive Impact
- Other: Quality Degradation
Developer Pattern
CWE-383 is the kind of defect developers can usually prevent with explicit validation, safer framework defaults, and tests that exercise hostile input or unsafe state transitions.
Confidence
high confidence from CWE-383, 4.20.
Official CWE Definition
CWE-383: J2EE Bad Practices: Direct Use of Threads
Thread management in a Web application is forbidden in some circumstances and is always highly error prone.
Thread management in a web application is forbidden by the J2EE standard in some circumstances and is always highly error prone. Managing threads is difficult and is likely to interfere in unpredictable ways with the behavior of the application container. Even without interfering with the container, thread management usually leads to bugs that are hard to detect and diagnose like deadlock, race conditions, and other synchronization errors.
Developer And Remediation Guidance
How teams prevent and detect this weakness
Causes
- In the following example, a new Thread object is created and invoked directly from within the body of a doGet() method in a Java servlet.
Remediation
- Architecture and Design: For EJB, use framework approaches for parallel execution, instead of using threads.
Detection
- Automated Static Analysis: Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
