=> Successful exploitation allows an unauthenticated, remote attacker to execute arbitrary code on the targeted system. => The vendor has released updates to resolve these issues.Ĭustomers are advised to visit Azul Java webpage and download patched Zulu versions. This QID executes "java -version 2>&1" command and checks for the zulu version on Linux Operating Systems This QID checks for "HKLM\Software\Azul Systems\Zulu" and "HKLM\Software\Wow6432Node\Azul Systems\Zulu 32-bit" subkeys and fetch azul version on Windows Operating Systems JDK by Azul also known as Zulu.Īzul Java is exposed to four remotely exploitable vulnerabilities that affect various components.Īzul Java Versions prior to 6.32(PSU), 7.37(CPU)/7.38(PSU), 8.45(CPU)/8.46(PSU), 11.38(CPU)/11.39(PSU), 13.30(CPU)/13.31(PSU), 14.28(PSU) => Azul - Java Platform for modern enterprise.

"For Java 6, we didn't manage to achieve a full sandbox compromise, except for the issue discovered in Apple Quicktime for Java software." "Java 7 was surprisingly much easier for us to break," Gowdiak said. "This specific issue might be however a little bit more difficult to find."īased on the experience of Security Explorations researchers with hunting for Java vulnerabilities so far, Java 6 has better security than Java 7. The new vulnerability discovered by Security Explorations in Java 7 Update 7 can be combined with some of the vulnerabilities left unpatched by Oracle to achieve a full JVM sandbox bypass again.
"Independent discoveries can never be excluded," Gowdiak said. It happened on multiple occasions for different bug hunters to discover the same vulnerability in the same product independently and this is what might have also happened in the case of the two actively exploited Java vulnerabilities that were addressed by Java 7 Update 7. Security researchers have always warned that if vendors take too much time to address a reported vulnerability it might be discovered by the bad guys in the meantime, if they don't already know about it. It's not clear if Oracle will release a new Java security update in October as it previously planned. Gowdiak doesn't know when Oracle plans to address the remaining vulnerabilities reported by Security Explorations in April or the new one submitted by the security company on Friday. "A new idea came, it was verified and it turned out that this was it."

"Once we found that our complete Java sandbox bypass codes stopped working after the update was applied, we looked again at POC codes and started to think about the possible ways of how to fully break the latest Java update again," Gowdiak said.
The new vulnerability discovered by Security Explorations in Java 7 Update 7 can be combined with some of the vulnerabilities left unpatched by Oracle to achieve a full JVM sandbox bypass again. However, this only happened because the "exploitation vector" was removed, not because all vulnerabilities targeted by the exploits were patched, Gowdiak said. The removal of the getField and getMethod methods from the implementation of the class in Java 7 Update 7 disabled all of Security Explorations' PoC exploits, Gowdiak said. The reports were accompanied by a total of 16 proof-of-concept exploits that combined those vulnerabilities to fully bypass the Java sandbox and execute arbitrary code on the underlying system.
