Insecure Data Storage
CWE : CWE-312
Description :
Insecure data storage vulnerabilities occur when development teams assume that users
or malware will not have access to a mobile device’s file system and subsequent sensitive
information in data-stores on the device. File systems are easily accessible.
Organizations should expect a malicious user or malware to inspect sensitive data stores.
Usage of poor encryption libraries is to be avoided. Rooting or jailbreaking a mobile
device circumvents any encryption protections. When data is not protected properly,
specialized tools are all that is needed to view application data.
Affected Path(s) :

Impact :
Insecure data may result in the following business impacts: • Identity theft; • Privacy
violation; • Fraud; • Reputation damage; • External policy violation (PCI); or • Material
loss.
Recommendation :
1. It is important to threat model your mobile app, OS, platforms and frameworks to
understand the information assets the app processes and how the APIs handle
those assets. It is crucial to see how they handle the following types of features :
1. URL caching (both request and response);
2. Keyboard press caching;
3. Copy/Paste buffer caching;
4. Application backgrounding;
5. Intermediate data
6. Logging;
7. HTML5 data storage;
8. Browser cookie objects;
9. Analytics data sent to 3rd parties.
2. Also, it is recommended to encrypt the user data in device internal storage.

Evidence/Proof Of Concept :
Step 1: Login to the application, access the internal pages and click on logout. It is observed
that even after the user get logged out, the JWT token was still saved in the cookie storage as
shown below.

Step 2: The JWT token reveals the sensitive information like username etc., as shown below.

Step 3: Access the above URL, here Insecure data storage as shown that.
