CVE-1999-0045 : 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.

Apache <= 1.1,NCSA httpd <= 1.5.2,Netscape Commerce Server 1.12/Communications Server 1.1/Enterprise Server 2.0 a nph-test-cgi Vulnerability source: https://www.securityfocus.com/bid/686/info Description as given by Josh Richards: A security hole exists in the nph-test-cgi script included in most UNIX based World Wide Web daemon distributions. The nph-* scripts exist to allow 'non-parsed headers' to be sent via the HTTP protocol (this is not the cause of this security problem, though). The problem is that nph-test-cgi, which prints out information on the current web environment (just like 'test-cgi' does) does not enclose its arguments to the 'echo' command inside of quotes....shell escapes are not possible (or at least I have not found them to be--yet) but shell *expansion* is.... This means that _any_ remote user can easily browse your filesystem via the WWW. This is a bug with the nph-test-cgi script and _not_ the server itself. Enter the URL: <http://yourwebserver.com/cgi-bin/nph-test-cgi?*> Replace <yourwebserver.com> with the hostname of a server running a web daemon near you.
