Unspecified vulnerability in the Deployment component in Oracle Java SE and Java for Business 6 Update 21 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors. NOTE: the previous information was obtained from the October 2010 CPU. Oracle has not commented on claims from a reliable researcher that this is related to "how Web Start retrieves security policies," BasicServiceImpl, and forged policies that bypass sandbox restrictions.

  • Detect delivery of a forged all.policy file containing AllPermission grant over HTTP; this is the payload used to escape the Java sandbox.
  • Alert on Java Web Start (javaws) processes spawning unexpected child processes or writing to the default java sandbox policy file, as the exploit overwrites it via parameter injection into BasicServiceImpl.
  • Look for JAR files served with Content-Type: application/octet-stream that contain both BasicServiceExploit.class and Exploit.class, which are the exploit class files for CVE-2010-3563.
  • User-visible indicator: multiple popup windows stating Java is 'Downloading application.' may appear on victim machines during exploitation.
  • ·The vulnerability affects Java 6 prior to Update 22 only; Update 22 and later are not affected.
  • ·The Metasploit module targets Windows x86 by default but also supports a generic Java payload target, meaning non-Windows Java environments may also be at risk.
