Adobe has released a hotfix to address an important vulnerability in the company’s ColdFusion development platform.
The hotfix includes an updated version of BlazeDS, a server-based Java remoting and web messaging technology. Adobe revealed earlier this month that BlazeDS is plagued by an XML External Entity (XXE) vulnerability that can result in information disclosure (CVE-2015-3269).
The vulnerability affects ColdFusion 10 update 16 and earlier versions, and ColdFusion 11 update 5 and earlier versions. The flaw has been addressed with the release of ColdFusion 10 update 17, and ColdFusion 11 update 6.
Adobe has provided detailed instructions on how to apply the hotfix for both ColdFusion 10 and 11. The company also advises developers to apply the security configuration settings described on the ColdFusion Security page, and review the lockdown guides for the platform.
The vulnerability has been rated “important” and assigned a priority rating of 2. This indicates that the security hole can be exploited to compromise data security, and it affects a product that has historically been at elevated risk. Adobe says it’s not aware of any in the wild exploits targeting this flaw, and the priority 2 rating indicates that the company does not expect to see exploits too soon.
The flaw was reported to Adobe by Matthias Kaiser of Code White. The issue was first addressed on August 18 in LiveCycle Data Services, which also includes BlazeDS, with the release of a security hotfix.
