Javascript Security Flaws Discovered
Polish researchers have released technical details and attack code for 30 security issues affecting Oracle’s Java Cloud Service. Some of the flaws make it possible for attackers to read or modify users’ sensitive data or to execute malicious code.
Security Explorations said it would normally withhold public airings until after any vulnerability has been fixed. But apparently Oracle representatives failed to resolve some of the more crucial issues including bypasses of the Java security sandbox, bypasses of Java whitelisting rules, the use of shared WebLogic server administrator passwords, and the availability of plain-text use passwords stored in some systems.
Oracle apparently has admitted to the researchers that it cannot promise whether it will be communicating resolution of security vulnerabilities affecting their cloud data centres in the future.
Adam Gowdiak, CEO of Security Explorations said Oracle unveiled the Java Cloud Service in 2011 and held it up as a way to better compete against Salesforce.com.
Java 6 Security Hole Found
Security firms are urging users of Oracle’s Java 6 software to upgrade to Java 7 as soon as possible to avoid becoming the victims of active cyber attacks.
F-secure senior analyst Timo Hirvonen warned about the exploit this weekend over Twitter, advising that he had found an exploit in the wild actively targeting an unpatched vulnerability in Java 6, named CVE-2013-2463.
PoC for CVE-2013-2463 was released last week, now it’s exploited in the wild. No patch for JRE6… Uninstall or upgrade to JRE7 update 25.

CVE-2013-2463 was addressed by Oracle in the June 2013 Critical Patch Update for Java 7. Java 6 has the same vulnerability, as Oracle acknowledged in the update, but since Java 6 became unsupported in April 2013, there is no patch for the Java 6 vulnerability.
Cloud security provider Qualys described the bug as an “implicit zero-day vulnerability”. The firm’s CTO Wolfgang Kandek said he had seen it included in the spreading Neutrino exploit kit threat, which “guarantees that it will find widespread adoption”.
“We know about its existence, but do not have a patch at hand,” Kandek said in a blog post. “This happens each time a software package loses support and we track these instances in Qualysguard with our ‘EOL/Obsolete’ detections, in this case.
“In addition, we still see very high rates of Java 6 installed, a bit over 50 percent, which means many organisations are vulnerable.”
Like F-secure, Kandek recommended that any users with Java 6 upgrade to Java 7 as soon as they can.
“Without doubt, organisations should update to Java 7 where possible, meaning that IT administrators need to verify with their vendors if an upgrade path exists,” he added.
80% Of Browsers Found To Be At Risk Of Attack
Comments Off on 80% Of Browsers Found To Be At Risk Of Attack
About eight out of every ten internet browsers run by consumers are vulnerable to attack by exploits of already-patched bugs, a security expert said today.
The poor state of browser patching stunned Wolfgang Kandek, CTO of security risk and compliance management provider Qualys, which presented data from the company’s free BrowserCheck service Wednesday at the RSA Conference in San Francisco.
“I really thought it would be lower,” said Kandek of the nearly 80% of browsers that lacked one or more patches.
BrowserCheck scans Windows, Mac and Linux machines for vulnerable browsers, as well as up to 18 browser plug-ins, including Adobe’s Flash and Reader, Oracle’s Java and Microsoft’s Silverlight and Windows Media Player.
When browsers and their plug-ins are tabulated together, between 90% and 65% of all consumer systems scanned with BrowserCheck since June 2010 reported at least one out-of-date component, depending on the month. In January 2011, about 80% of the machines were vulnerable. Read more….
