Adobe Patches Code Execution Flaws in Prelude, Experience Manager, Lightroom

Adobe on Tuesday announced that security updates for its Prelude, Experience Manager and Lightroom products patch critical arbitrary code execution vulnerabilities.

Adobe on Tuesday announced that security updates for its Prelude, Experience Manager and Lightroom products patch critical arbitrary code execution vulnerabilities.

In the Windows and macOS versions of the Prelude video logging and ingest tool, Adobe fixed a critical uncontrolled search path issue that can lead to arbitrary code execution in the context of the targeted user.

Uncontrolled search path issues are typically DLL hijacking vulnerabilities whose exploitation requires the attacker to have elevated privileges on the targeted system in order to plant a malicious DLL file that would get executed by a legitimate application.

The flaw was reported to Adobe by Hou JingYi of Chinese cybersecurity firm Qihoo 360. The same researcher also informed Adobe of a similar uncontrolled search path flaw affecting the Windows and macOS versions of the photo editing and organizing software Lightroom.

In its Experience Manager marketing product, Adobe fixed two vulnerabilities: an important-severity blind server-side request forgery (SSRF) bug that can lead to the disclosure of sensitive data, and a critical stored cross-site scripting (XSS) issue that can lead to JavaScript code execution in the browser.

The software giant has also informed customers that it has updated over a dozen Experience Manager dependencies to patch various types of vulnerabilities, including resource consumption, SSRF, XXE injection, improper authorization, code execution, and directory traversal issues.

Adobe said it was not aware of any attacks exploiting these vulnerabilities and, based on the priority ratings assigned to the flaws, the company does not expect them to be targeted by threat actors.

It would not be surprising if these are not the last security updates released by Adobe this year, considering that the company often releases another round of patches after Patch Tuesday.

UPDATE 12/09/2020: Adobe on Wednesday released an advisory to inform customers that an important-severity information disclosure vulnerability has been patched in Acrobat and Reader.
