Java Card Proof Of Concepts

Security Explorations has discovered multiple security vulnerabilities in the reference implementation of Java Card technology from Oracle used in financial, government, transportation and telecommunication sectors among others. As for the impact, the vulnerabilities found make it possible to break memory safety of the underlying Java Card VM. As a result, full access to smartcard memory could be achieved, applet firewall could be broken or native code execution could be gained. This archive contains the proof of concept code that demonstrates these vulnerabilities which were originally made public in March of 2019.
