NONE Summary
Product: Apache Cordova Android 5.2.2 and earlier. The application calls methods of the Log class. Messages passed to these methods (Log.v(), Log.d(), Log.i(), Log.w(), and Log.e()) are stored in a series of circular buffers on the device. By default, a maximum of four 16 KB rotated logs are kept in addition to the current log. The logged data can be read using Logcat on the device. When using platforms prior to Android 4.1 (Jelly Bean), the log data is not sandboxed per application; any application installed on the device has the capability to read data logged by other applications.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Fuzzing and observing application log data/errors for application mapping An attacker sends random, malformed, or otherwise unexpected messages to a target application and observes the application's log or error messages returned. Fuzzing techniques involve sending random or malformed messages to a target and monitoring the target's response. The attacker does not initially know how a target will respond to individual messages but by attempting a large number of message variants they may find a variant that trigger's desired behavior. In this attack, the purpose of the fuzzing is to observe the application's log and error messages, although fuzzing a target can also sometimes cause the target to enter an unstable state, causing a crash. By observing logs and error messages, the attacker can learn details about the configuration of the target application and might be able to cause the target to disclose sensitive information.
