Glexia's Take

CWE-694: Use of Multiple Resources with Duplicate Identifier

Use of Multiple Resources with Duplicate Identifier represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.

Executive Impact

  • Access Control: Bypass Protection Mechanism: If unique identifiers are assumed when protecting sensitive resources, then duplicate identifiers might allow attackers to bypass the protection.
  • Other: Quality Degradation

Developer Pattern

CWE-694 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-694, 4.20.

Official CWE Definition

CWE-694: Use of Multiple Resources with Duplicate Identifier

The product uses multiple resources that can have the same identifier, in a context in which unique identifiers are required.

If the product assumes that each resource has a unique identifier, the product could operate on the wrong resource if attackers can cause multiple resources to be associated with the same identifier.

Developer And Remediation Guidance

How teams prevent and detect this weakness

Causes

  • These two Struts validation forms have the same name. It is not certain which form will be used by Struts. It is critically important that validation logic be maintained and kept in sync with the rest of the product.

Remediation

  • Architecture and Design: Where possible, use unique identifiers. If non-unique identifiers are detected, then do not operate any resource with a non-unique identifier and report the error appropriately.

Detection

  • Code review
  • SAST
  • DAST
  • Focused regression tests
