Digea Digital Provider SA is a company set up by private national television channels ALPHA, ALTER, ANTENNA, MACEDONIA TV, MEGA, SKAI and STAR.
7 February 2014 was awarded a successful bidder for all rights to use national and regional coverage radio frequencies. The company's goal was to build the country's digital terrestrial network and complete the transition from analogue to digital television.
By the end of 2013, the company activated 13 broadcast centers across Greece, giving access to the free digital terrestrial television signal over 70% of the country's population.
With the completion of the terrestrial digital switchover, 156 broadcast centers were activated, covering the 95% of the Greek population with a digital signal.
The company's achievements are impressive, but according to our well-known researcher Nyo (GHS), the official website of Digea allows malicious or non-malicious users of Cross-site scripting or XSS.
Cross-site scripting or XSS refers to the exploitation of various vulnerabilities of computing systems by inserting HTML or Javascript into a web page. A malicious user could enter code on a webpage through an entry text for example which, having been filtered from the page correctly, could cause problems for the site's administrator or visitor.
Example:
http://www.example.com/index.html?name=
The malicious user could:
Trap bills and personal data
Change website settings
Stolen cookies
Raise false ads through a link
Vulnerability refers to the system's inability to filter and reject any harmful inputs.

According to the researcher, he published the XSS in response to the video "MEGA - DIGEA threatens with black!"
The video states that “according to reports, the Board of Directors of Digea has decided to weaken the station's signal despite the fact that negotiations are ongoing between shareholders and banks to find a solution. This means that either a 'broken' pixel image will be displayed or a 'frozen' image and only audio will be displayed. ”
He also says that XSS was not publicized to support a private channel but the end-user viewer.
XSS affects the whole page through javascript and can deform it completely.
SecNews.gr is available to everyone from the Digea.gr management team for details of the vulnerability.
