APP: VMware Server ISAPI Extension Remote Denial Of Service
This signature detects attempts to exploit a known vulnerability in the ISAPI extension provided by VMware Server to extend support to IIS for running Perl scripts. By supplying overly large data to the ISAPI extension iisperl.dll in a POST request, a remote attacker can terminate the IIS service and create a denial-of -service condition. Upon processing malicious POST request, the affected IIS server process terminates, which triggers a denial-of-service condition. On most installations, the service restarts automatically to resume the normal operation.
Extended Description
VMware ISAPI extensions are prone to a remote denial-of-service vulnerability. A remote attacker can exploit this issue to cause the affected IIS service to shut down, denying service to legitimate users.
