Website vulnerabilities fall, but hackers become more skilled

The number of coding mistakes on websites continues to fall but companies are slow to fix issues that could be exploited by hackers working with improved attack tools, a security expert said.

The average number of serious vulnerabilities introduced to websites by developers in 2011 was 148, down from 230 in 2010 and 480 in 2009, said Jeremiah Grossman, chief technology officer for WhiteHat Security, which specialises in testing websites for security issues. Grossman spoke on the sidelines of the Open Web Application Security Project conference in Sydney on Monday.

The vulnerabilities are contained within custom website code and are not issues that can be fixed by applying patches from, for example, Microsoft or Oracle, Grossman said. According to WhiteHat Security statistics, it takes organisations an average of 100 days to fix about half of their vulnerabilities.

The risk is that vulnerabilities which haven’t been speedily remedied could be found by a hacker, resulting in a high-profile data breach such as those that affected Sony, the analyst firm Stratfor Global Intelligence, and ATT.

Hackers are honing their skills and are becoming better focused. They are using a wider array of improved tools in order to find coding problems in websites. “Offense gets better every year,” Grossman said.

Security analysts in Grossman’s company constantly try to hack websites belonging to major financial institutions and other companies — with permission. Developers in those companies don’t tell WhiteHat when they roll out new features or make changes. WhiteHat’s hackers go to work, trying to find cross-site scripting flaws, SQL injection or information leakage vulnerabilities.

“We are constantly smashing [websites],” Grossman said. “We’re LulzSec or Anonymous 24/7. We don’t stop.”

Companies decide whether they want to fix the problems, which often involves reassigning a developer working on a new feature that the business needs to roll out, Grossman said. It’s a gamble whether or not to fix, since the vulnerability may never be found by a hacker but could cost the company dearly if it is.

“Do you take the developer off that [project] and put them on correcting a vulnerability that they know they have but may or may not get exploited and may or may not cost them any money whatsoever?” Grossman said.

The best scenario is to write good software from the start, with a keen eye on security. “We’re not going to get perfect at software, but we can get economically good enough software,” Grossman said.

Adobe Reader vulnerabilities patched and bundled Flash Player removed

Adobe Systems has released new versions of Adobe Reader 10.x and 9.x, addressing four arbitrary code execution vulnerabilities and making several security-related changes to the product, including the removal of the bundled Flash Player component from the 9.x branch.

All of the vulnerabilities fixed in the newly released Adobe Reader 10.1.3 and Adobe Reader 9.5.1 versions could be exploited by an attacker to crash the application and potentially take control of the affected system, Adobe said in its APSB12-08 security bulletin. Users are advised to install these updates as soon as possible.

The company also announced that Adobe Reader 9.5.1 no longer includes authplay.dll, a Flash Player library that was bundled with previous versions of the program to enable the rendering of Flash content embedded in PDF documents.

The presence of the authplay.dll component in Adobe Reader has caused some security issues in the past, primarily because of the inconsistent update schedules for Adobe Reader and Flash Player.

Authplay.dll contains much of the stand-alone Flash Player’s code, which also means that it shares most of the latter’s vulnerabilities. However, while Flash Player is patched by Adobe when needed, Adobe Reader used to follow a more strict quarterly update cycle.

Product Security Incident Response Team

This often resulted in situations where some known vulnerabilities got patched in Flash Player, but remained exploitable through authplay.dll for months, until the next scheduled update for Adobe Reader.

Such is the case with the new Adobe Reader 10.1.3 version, which incorporates three previous Flash Player security updates that were released separately during the last three months.

Starting with Adobe Reader 9.5.1, Adobe Reader 9.x will use the stand-alone Flash Player plug-in that’s already installed on computers for browsers like Mozilla, Safari or Opera, in order to play Flash content in PDF files.

This functionality will not work with the ActiveX-based Flash Player plug-in for Internet Explorer or the special Flash Player plug-in version bundled with Google Chrome.

Adobe plans to remove authplay.dll from the 10.x branch of Adobe Reader in the future as well and is currently working on APIs (application programming interfaces) to make this possible, said David Lenoe, group manager for Adobe’s Product Security Incident Response Team (PSIRT).

Vulnerability management vendor Secunia welcomes Adobe’s decision to remove authplay.dll from Adobe Reader, because it will make addressing Flash vulnerabilities easier for users, Secunia’s chief security specialist, Carsten Eiram, said.

3D content rendering

“However, the default option in Adobe Reader should be to not support Flash content in PDF files, requiring users to specifically enable this,” Eiram said. “Most users do not need it and Flash content embedded in PDF files has historically been exploited as a vector to compromise Adobe Reader users’ systems.”

This is actually the approach Adobe has taken with the 3D content rendering feature. Starting with Adobe Reader 9.5.1, this feature has been disabled by default because it’s not commonly used and can be exploited in certain circumstances, Lenoe said.

“We’ve seen 0-days targeting this part of the functionality and it seems to be one of the more flawed features,” Eiram said. “We’ve for a long time been recommending users to disable the plugins used for 3D parsing.”

In addition to making these security patches and changes, Adobe also decided to cancel its quarterly update cycle for Adobe Reader and Acrobat and return to its previous patch-as-needed policy. Future Adobe Reader updates will continued be released on the second Tuesday of the month, but it will no longer happen every four months.

“We will publish updates to Adobe Reader and Acrobat as needed throughout the year to best address customer requirements and keep all of our users safe,” Lenoe said.

“The quarterly update cycle never worked for Adobe,” Eiram said. “Vulnerability fixes should always be provided as quickly as possible; it’s not justifiable to unnecessarily postpone a vulnerability fix for up to three months simply due to policy reasons.”

Flashback malware evolves to exploit unpatched Java vulnerabilities

The Flashback Trojan horse is a fairly recent malware package developed for OS X that attempts to steal personal information by injecting code into Web browsers and other applications on an OS X system. When these programs are then launched, the malicious code attempts to contact remote servers and upload screenshots and other personal information to them.

This malware was initially found in September 2011 while being distributed as a fake Flash Player installer (hence its “Flashback” name). In in the past few months it has evolved to exploiting Java vulnerabilities to  target
Mac systems.

While the exploits used by recent variants of the Flashback malware have been for older, patched vulnerabilities, over the weekend another variant surfaced that appears to be taking advantage of Java vulnerability (CVE-2012-0507) that currently is unpatched in OS X.

For OS X systems with Java installed, simply visiting a malicious Web site containing the malware will result in one of two installation routes, both of which have been characteristic of prior variants of the malware. First it will ask for an administrator password, and if supplied it will install its payload into target programs within the /Applications folder. However, if no password is supplied, then the malware will still install to the user accounts where it will run in a more global manner.

While Apple does have a built-in malware scanner called XProtect, which will catch some variants of the Flashback malware, this scanner will not detect files being executed by the Java runtime, so these latest Flashback variants bypass this mode of protection.

This shortcoming of XProtect, coupled with Java for OS X currently being unpatched, might be concerning; however, in most cases Mac users should be relatively safe. Starting with OS X 10.6 Snow Leopard, Apple stopped including a Java runtime with OS X, so if you have purchased a new system with OS X 10.6 or later, or have formatted and reinstalled either OS X 10.6 or 10.7, then you will, by default, not be affected by this malware.

However, if you do have Java installed on your system, then for now the only way to prevent this malware from running is to disable Java. This can be done in the Security preferences in
Safari, or by unchecking the Java runtime entries in the Java Preferences utility.

Even though new Mac systems cannot be affected by this malware in their default configurations, this development does outline a problem with how threats are handled in cross-platform runtimes such as Java. When vulnerabilities like the one here are discovered, they are often distributed among malware creators via exploit kits like Blackhole, which offer tools and code that make developing malware far easier for the criminals to do.

Because of the availability of these kits, even if the runtime for one platform is patched, then any lag in development for the other platforms (as is the case with Java on OS X) will provide a larger window of opportunity for malware developers to take advantage.

It appears this is exactly what the criminals behind the Flashback malware are doing, and as a result it puts those who use Java at an increased risk.
