    Hi
    
    Perhaps you could be helped by Vigilantes classification:
    
    ---cut starts here---
    High Risk 
    A high risk vulnerability provides direct access to an organization's private 
    assets, providing the potential for theft, deletion or alteration of those 
    assets. 
    
    Medium Risk 
    A medium risk vulnerability provides access to an organization's private 
    assets in combination with one or more other vulnerabilities. By exploiting 
    multiple medium risk vulnerabilities, an attacker will have the capability 
    for theft, deletion or alteration of an organization's assets. 
    
    
    VIGILANTe also considers denial-of-service attacks to be medium risk 
    vulnerabilities.
    
    Low Risk
     A low risk vulnerability does not lead directly to access of an 
    organization's private assets, but provides a excessive information that 
    might help an attacker gain unauthorized access. 
    ---cut ends here---

    I do believe there would also be a need for classification of a vulnerability 
    could be exploited remotely or/and locally.
    
    There would also be a need for probablity which I do guess is very subjectivem 
    but do depends of the customers enviroment. The probability for someone 
    exploiting a vulnerabliity would be large on a public accessible server, 
    medium for a server on the internal network, and low on a network with no 
    users.
    
    
    Best regards,
