- Status
- Draft

- Java
- CWE version
- 5.0
Description
The product uses J2EE with a configuration that transmits data without encryption.
Common consequences
• Confidentiality: Read Application Data — An attacker may be able to read the data sent in plaintext.
• Integrity: Modify Application Data — Information sent over a network can be compromised while in transit. An attacker may be able to modify the contents of data sent in plaintext.
Potential mitigations
• [System Configuration] The product configuration should ensure that SSL or an encryption mechanism of equivalent strength and vetted reputation is used for all access-controlled pages.
Detection methods
• 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.)
