We generalize Kahn's correspondence between Cohen--Macaulay modules over normal surface singularities over an algebraically closed field and vector bundles over some projective curves to abstract surface singularities, which need not be algebras over a field. As a consequence, we also generalize to the abstract case the Drozd--Greuel criterion for tameness of curve singularities.
