CVE-2002-0440
HighSummary
Trend Micro InterScan VirusWall HTTP proxy 3.6 with the 'Skip scanning if Content-length equals 0' option enabled allows malicious web servers to bypass content scanning via a Content-length header set to 0, which is often ignored by HTTP clients.
Risk Assessment
Organizations may be exposed to malware attacks as content scanning is not performed for responses with a content length of 0.
Recommendation
It is recommended to disable the 'Skip scanning if Content-length equals 0' option in the InterScan VirusWall configuration to minimize the risk of bypassing scans.
