CVE-2000-0780 : Detail

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

To this end the IMail server provides a web server typically running on port 8383 for it's end users to access. Via this interface users may read and send mail, as well as mail with file attachments. Certain versions of IMail do not perform proper access validation however resulting in users being able to attach files resident on the server. The net result of this is users may attach files on the server to which they should have no access. This access is limited to the user privileges which the server is being run as, typically SYSTEM. It should be noted that once a user attachs the files in question the server deletes them. Here is a sample mail header sent by IMAIL web services which has an attachment. Please note that this is line wrapped for readability.
