@RISK provides a reliable weekly summary of (1) newly discovered attack vectors, (2) vulnerabilities with active new exploits, (3) insightful explanations of how recent attacks worked, and other valuable data

A key purpose of the @RISK is to provide the data that will ensure that the 20 Critical Controls (the US and UK benchmark for effective protection of networked systems) continue to be the most effective defenses for all known attack vectors. But since it is also valuable for security practitioners, SANS is making it available to the 145,000 security practitioners who have completed SANS security training and others at their organizations who hope to stay current with the offensive methods in use.

TOP VULNERABILITY THIS WEEK: Oracle announced that it would not be patching the recently discovered Java sandbox breakout vulnerability until February 2013. While exploits are not known to be circulating in the wild at this point, as researcher Adam Gowdiak has kept a tight lid on the technique, enough details are available that users should consider the likelihood of future exploitation very high. Researchers around the globe are urging Java users to disable it in their browser if at all possible, and to at least ensure that other Critical Patch Updates from Oracle are being installed in the interim.

Title: Oracle announces Java 0-day to remain unpatched until February
Description: A Java sandbox escape vulnerability discovered by Polish researcher Adam Gowdiak in September will not be fixed until the February 2012 Oracle Critical Patch Update, according to the firm. While Oracle claims that this is due to extensive testing of a complex fix, Gowdiak counters that he was able to fix the bug in under a half an hour in the open-source version of Java. While no details of the vulnerability have been released publicly, and no indication of exploitation in the wild has surfaced to date, the considerable delay in an official patch leaves users at what many would consider undue risk of attack. The Sourcefire VRT strongly recommends that users disable Java in their browsers in the interim.
Snort SID: N/A
ClamAV: N/A

Title: Novell ZENWorks default admin credentials
Description: Version 7.5 of Novell's ZENWorks Asset Management system contains hard-coded administrative credentials in a pair of web-accessible functions. Attackers can use a web browser to leverage these functions into the ability to read arbitrary files on the impacted system and retrieve the plaintext credentials for the service itself. A Metasploit module exploiting this weakness also exists. Users should patch their systems immediately, as this vulnerability represents a trivial entry point into a network.
Snort SID: 24435, 24436
ClamAV: N/A

Title: New heap spray technique released
Description: Researchers with Core Labs have released proof-of-concept code for a new heap spray technique targeting the HTML 5 framework. Functional against most modern browsers, this technique is also effective against smartphones, media centers, and other devices which render HTML 5. Attacks in the wild are presumed to exist at this time, given the relative ease of plugging the PoC code into existing exploitation frameworks.

Title: Anonymous publishes 1.35 GB of data from Italian State Police
Description: A massive collection of sensitive files from Italian State Police servers, including details of wiretaps, security system internals, etc., was released by Anonymous on Tuesday. Potentially much more destructive than recent DDoS attacks, the impact from this disclosure could last well into the future, causing political and/or operational damage for the Italian government and possibly others.
