Adobe patches important flaw in LiveCycle Data Services

The vulnerability could be exploited to extract sensitive information from servers

Adobe Systems released a security patch for LiveCycle Data Services, a development tool used by businesses to synchronize data between back-end servers and rich Internet applications built with Adobe Flex or AIR.

The hotfix is available for LiveCycle Data Services 3.0.0, 4.5.1, 4.6.2 and 4.7.0 and addresses a vulnerability that could lead to information disclosure.

The flaw is tracked as CVE-2015-3269 in the Common Vulnerabilities and Exposures database and is rated important by Adobe.

The issue is associated with parsing crafted XML entities and falls into a class of vulnerabilities known as XML External Entity (XXE).

According to OWASP, a non-profit organization that produces guidelines for preventing Web flaws, XXE vulnerabilities occur when an application parses XML input that contains a reference to an external entity.

The attack can be used to read sensitive files from a server, scan internal ports, access the server's local network and more. The impact depends on the type of extracted data. In some cases, such information could allow a hacker to plan or execute a more sophisticated attack.

Adobe has also published a support article with detailed information on applying the patch to an affected LiveCycle Data Services application. The steps involve replacing a file called flex-messaging-core.jar and turning the allow-xml-external-entity-expansion option to false in the configuration file.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
