Official CWE-219 CWE context with Glexia analysis, remediation guidance, related CVEs, and ATT&CK context.
Glexia's Take
CWE-219: Storage of File with Sensitive Data Under Web Root
Storage of File with Sensitive Data Under Web Root represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
Executive Impact
- Confidentiality: Read Application Data
Developer Pattern
CWE-219 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-219, 4.20.
Official CWE Definition
CWE-219: Storage of File with Sensitive Data Under Web Root
The product stores sensitive data under the web document root with insufficient access control, which might make it accessible to untrusted parties.
Besides public-facing web pages and code, products may store sensitive data, code that is not directly invoked, or other files under the web document root of the web server. If the server is not configured or otherwise used to prevent direct access to those files, then attackers may obtain this sensitive data.
Developer And Remediation Guidance
How teams prevent and detect this weakness
Causes
- Missing validation
- Unsafe defaults
- Insufficient authorization or memory-safety invariant
Remediation
- Implementation,System Configuration: Avoid storing information under the web root directory.
- System Configuration: Access control permissions should be set to prevent reading/writing of sensitive files inside/outside of the web directory.
Detection
- Code review
- SAST
- DAST
- Focused regression tests
