Viewing Cached Dataįor penetration testers needing a proof of concept for cached data, Chrome and FireFox browsers no longer store cached pages in readable files. Expires is also identical to the max-age directive of the Cache-Control header and is ignored when max-age is used. ExpiresĮxpires instructs the client how long to retain the content. Pragma supports only one directive, no-cache. Pragma is a header for HTTP/1.0 clients that do not support HTTP/1.1. no-store instructs browsers not to store the content locally and is the only necessary directive. No-store is the strongest and preferred directive for secure applications. private does not prevent any caching by web browsers. The term ‘private’ here is only reserved for “shared caches” such as proxies and does not apply to the end user. no-cache only forces validation of the cached content, so the browser may store the data, but must check for new versions when the page is requested again. No-cache is the most frequent offender, where despite it’s name, it does not prevent data being cached locally.

Cache-ControlĬache-Control has a number of directives which are frequently misunderstood. These are the core controls to instruct web clients on how data should be cached. There are three cache controls relevant to a penetration test: Cache-Control, Expires, and Pragma. The cached data (even when it’s not sensitive) indicates the owner is a user of your application, and the actor can then further target the owner. A malicious actor gains temporary access to a user’s device.Sensitive data stored locally is exposed to others in shared workstation environments, or forensically recovered if a device is lost.Let’s first review some scenarios where caching may pose risk: On the other hand, performance improves as artifacts and data can be cached to avoid excessive requests.Īlthough ultimately a low risk in nearly all contexts, organizations must decide what levels of caching are acceptable for their applications. On one hand, security standards recommend that no application data is cached or stored in local browser directories. They control a balance between security and performance which is still frequently debated today. Resolving “Windows NetBIOS / SMB Remote Host Information Disclosure” (2020)Ĭache controls have been a fixture on application penetration test reports for over 20 years.
