Summary
Impact: Information Disclosure. Microsoft rating: Important. Not known to be exploited — Exploitation Unlikely. Customer action: Required.
Details
According to the CVSS metric, the attack vector is network (AV:N), user interaction is required (UI:R), and privileges required are low (PR:L). What does that mean for this vulnerability?
Exploitation of this vulnerability requires an authorized attacker on the domain to wait for a user to initiate a connection to a malicious server that the attacker has set up prior to the user connecting.
What type of information could be disclosed by this vulnerability?
An attacker who successfully exploited this vulnerability could potentially read portions of heap memory.
How could an attacker exploit this vulnerability?
An attacker authenticated on the domain could exploit this vulnerability by tricking a domain-joined user into sending a request to a malicious server via the Routing and Remote Access Service (RRAS) Snap-in. This could result in the server returning malicious data that might cause arbitrary code execution on the user's system.
