This vulnerability allows a remote attacker to disclose sensitive information on vulnerable installations of Adobe Reader DC. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the Weblink plugin.

An attacker can leverage this in conjunction with other vulnerabilities to execute code under the context of the current process.
