# Visonic PowerLink2 Vulnerabilities
#


### OVERVIEW

Independent researcher Aditya K. Sood has identified cross-site scripting and source code disclosure vulnerabilities in Visonic's PowerLink2 module. Visonic has produced an updated version to mitigate these vulnerabilities.
These vulnerabilities could be exploited remotely.



### AFFECTED PRODUCTS

The following PowerLink2 versions are affected:
PowerLink2, all versions prior to October 2016 firmware release.



### IMPACT

Successful exploitation of these vulnerabilities allows the attacker to gather information on how server side images are generated. Careful analysis combined with some additional information (from testing the product), allows the attacker to download images from the server.
Impact to individual organizations depends on many factors that are unique to each organization. NCCIC/ICS-CERT recommends that organizations evaluate the impact of these vulnerabilities based on their operational environment, architecture, and product implementation.



### BACKGROUND

Visonic is an Israel-based company and subsidiary of Tyco, that maintains offices in several countries around the world, including the US, UK, Denmark, Poland, Spain, Germany, Singapore, China, and Australia.
The affected product, PowerLink2, provides web interface to view and control an intrusion security system. According to Visonic, PowerLink2 modules are deployed in the Commercial Facilities sector. Visonic estimates that this product is used primarily in the United States and Europe with a small percentage in Asia.
