Overview
A vulnerability has been reported in Microsoft Windows Media Player versions 11 and 12 Network Sharing Service that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system.
Description
The Real Time Streaming Protocol (RTSP) is an application-level protocol for control over the delivery of data with real-time properties. RTSP provides an extensible framework to enable controlled, on-demand delivery of real-time data, such as audio and video. Sources of data can include both live data feeds and stored clips. This protocol is intended to control multiple data delivery sessions, provide a means for choosing delivery channels such as UDP, multicast UDP and TCP, and provide a means for choosing delivery mechanisms based upon RTP (RFC 1889). This vulnerability is caused due to improper handling of malformed RTSP packets by the Windows Media Player Network Sharing Service. The Network Sharing Service allows devices on the network to access shared content on the system.
An unauthenticated, remote attacker could exploit this vulnerability by sending malicious RTSP packets to the targeted device/system installed with vulnerable version of media player. While processing, the packets could cause an error condition that the attacker could take advantage to execute arbitrary code with the elevated privileges of the Network Sharing Service.
Workaround
- Disable Windows Media Player Network Sharing Service on affected systems
- Do not click on unknown or untrusted video streaming links
