RusCrypto CTF 2010 Full Disclosure

RusCrypto CTF is an open competition in information security held on Capture The Flag principle. At the beginning of the game teams have identical servers with installed vulnerable services.
Besides vulnerabilities in specially designed services, there are vulnerabilities common for real information systems: weak passwords, known vulnerabilities in OS/services, errors in configuration, real vulnerabilities in web applications (such as popular CMS).

During the competition, changes in the system can be made that can lead to additional vulnerabilities to competitors’ services. Competitors’ goal is to detect the vulnerabilities, eliminate them in their servers and do not break the server operation. Competitors also should use similar vulnerabilities on competitors’ servers to capture flags.

Teams earn points by:

  • Make your own services to be available all time;
  • Send messages about vulnerabilities and elimination methods (advisories) – the jury estimates notification completeness and proof of concept code (POC);
  • Send flags captured in competitors’ services;
  • Eliminate vulnerabilities on the servers without any damage to service performance;
  • Additional tasks;

And by special jury solution.

The jury continuously watches the competition, and from time to time add new flags and vulnerabilities to competitors’ servers, and also watch previously added flags and vulnerable services execution. Moreover, the system takes captured flags and recommendations how to eliminate detected vulnerabilities and ways how to use them (advisories).

There are several servers for every team infrastructure that have a number of predefined vulnerabilities.
