The vulnerability in Android's component Apache Harmony led to multiple compromises of a bitcoin transactions.
Vulnerable component: Google Android
CVSSv3 score: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C
CWE-ID: CWE-310 - Cryptographic Issues
The vulnerability allows a renote attacker to bypass security restriction on the target system.
The weakness is due to the use of an incorrect offset value by the engineNextBytes function in Apache Harmony, as used in the Java Cryptography Architecture (JCA) in Android . A remote attacker can leverage the resulting PRNG predictability, defeat cryptographic protection mechanisms and launch further attacks on the system.
Successful exploitation of the vulnerablity results in security bypass on the vulnerable system.
