Using a global Bayesian analysis, it is shown how the results from 7 and 8 $\textrm{TeV}$ searches for supersymmetry performed by the CMS experiment constrain the Minimal Supersymmetric Standard
Model (MSSM). The study is performed within the framework of the phenomenological
MSSM (pMSSM), a 19-parameter realization of the R-parity conserving weakscale
MSSM, that captures most of the latter's phenomenological features and which,
therefore, permits robust conclusions to be drawn about the MSSM.
