Title

PropertyGuru AgentNet Singapore App com.allproperty.android.agentnet BuildConfig.java hard-coded key

Summary

A security flaw has been discovered in PropertyGuru AgentNet Singapore App up to 23.7.10 on Android. This affects an unknown function of the file com/allproperty/android/agentnet/BuildConfig.java of the component com.allproperty.android.agentnet. The manipulation of the argument SEGMENT_ANDROID_WRITE_KEY/SEGMENT_TOS_WRITE_KEY results in use of hard-coded cryptographic key . The attack must be initiated from a local position. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
