Name: Use of Web Browser Cache Containing Sensitive Information

The web application does not use an appropriate caching policy that specifies the extent to which each web page and associated form fields should be cached.

General Informations

Modes Of Introduction

Implementation

Common Consequences

Scope Impact Likelihood
ConfidentialityRead Application Data

Note: Browsers often store information in a client-side cache, which can leave behind sensitive information for other users to find and exploit, such as passwords or credit card numbers. The locations at most risk include public terminals, such as those in libraries and Internet cafes.

Potential Mitigations

Phases : Architecture and Design
Protect information stored in cache.
Phases : Architecture and Design // Implementation
Use a restrictive caching policy for forms and web pages that potentially contain sensitive information.
Phases : Architecture and Design
Do not store unnecessarily sensitive information in the cache.
Phases : Architecture and Design
Consider using encryption in the cache.

Vulnerability Mapping Notes

Justification : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Comment : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

Related Attack Patterns

CAPEC-ID Attack Pattern Name
CAPEC-37 Retrieve Embedded Sensitive Data
An attacker examines a target system to find sensitive data that has been embedded within it. This information can reveal confidential contents, such as account numbers or individual keys/credentials that can be used as an intermediate step in a larger attack.
