Run app/console --version (for Symfony3: bin/console --version), it should give you a pretty good idea. On a random project of mine, the output is:

Symfony version 2.2.0-DEV - app/dev/debug

If you can't access the console, try reading symfony/src/Symfony/Component/HttpKernel/Kernel.php, where the version is hardcoded, for instance:

const VERSION         = '2.2.0';

Just in case you are wondering, console creates an instance of SymfonyBundleFrameworkBundleConsoleApplication. In this class constructor, it uses SymfonyComponentHttpKernelKernel::VERSION to initialize its parent constructor.
