Official CWE-317 CWE context with Glexia analysis, remediation guidance, related CVEs, and ATT&CK context.
Glexia's Take
CWE-317: Cleartext Storage of Sensitive Information in GUI
Cleartext Storage of Sensitive Information in GUI represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
Executive Impact
- Confidentiality: Read Memory,Read Application Data
Developer Pattern
CWE-317 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-317, 4.20.
Official CWE Definition
CWE-317: Cleartext Storage of Sensitive Information in GUI
The product stores sensitive information in cleartext within the GUI.
An attacker can often obtain data from a GUI, even if hidden, by using an API to directly access GUI objects such as windows and menus. Even if the information is encoded in a way that is not human-readable, certain techniques could determine which encoding is being used, then decode the information.

Remediation
- Use safe APIs
- Centralize the control
- Add regression tests
- Review logs and telemetry for attempted abuse
Detection
- Code review
- SAST
- DAST
- Focused regression tests
