    icat http://icat.nist.gov/icat.cfm (a CVE front-end) does it as described
    below. I'm sure there are other/better/worse ways... just an example.

    A vulnerability is "high severity" if:
       1. it allows a remote attacker to violate the security protection of a
    system (i.e. gain some sort of user or root account),
       2. it allows a local attack that gains complete control of a system,
       3. it is important enough to have an associated CERT/CC advisory.
    A vulnerability is "medium severity" if:
       1. it does not meet the definition of either "high" or "low" severity.
    A vulnerability is "low severity" if:
       1. the vulnerability does not typically yield valuable information or
    control over a system but instead gives the attacker knowledge that may help
    the attacker find and exploit other vulnerabilities.
       2. we feel that the vulnerability is inconsequential for most
    organizations.

    Subject: mapping vulnerabilities into high medium low risk

    Hi,

    Anyone know any open source methodology about categorizing
    vulnerabilities? When doing a Pent Test, I need to categorize a
    particular
    vulnerability into high medium or low risk. These vulnerabilities may be
    a
    web application vulnerability or may be a new system vuln that has yet
    to
    be discovered. So is there any open source methodology that give you a
    guide to how to categorize the vuln?
