Independent researcher Billy Rios has identified a heap-based buffer overflow in the Philips Xper application. Philips has produced an update that mitigates this vulnerability. Philips has tested the update and verified that it resolves the vulnerability.
This vulnerability could be exploited remotely.
The following Xper Information Management versions are affected:
Note: the following products are only affected if the XperConnect Broker is used in line.
Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code with administrator-level privileges, affecting the availability, integrity, and confidentiality of the system.
Impact to individual organizations depends on many factors that are unique to each organization. ICS‑CERT recommends that organizations evaluate the impact of this vulnerability based on their operational environment, architecture, and product implementation.
Philips is a global company that maintains offices in several countries around the world, including countries in Africa, Asia, Europe, Latin America, Middle East, and North America.
The affected product, Xper, is a Cardio Physiomonitoring system. According to Philips, Xper is deployed across the Healthcare and Public Health sector. Philips estimates that these products are used primarily in the United States and Europe with a small percentage in Asia.
The Xper Connect broker listens to Port 6000/TCP by default. By sending an HTTP request outside the bounds of the buffer to Port 6000/TCP, an attacker can cause a heap-based buffer resulting in loss of confidentiality, integrity, and availability.
