Vulnerability description

The vulnerability allows a remote attacker to perform denial of service (DoS) attack.

The vulnerability exists due to missing authorization when processing file uploads at the " /officescan/console/html/cgi/fcgiOfcDDA.exe" URL. A remote non-authenticated attacker can send a specially crafted HTTP PUT request with a malformed Content-Length header, upload an arbitrary number of large files to the SampleSubmission directory (i.e., \\PCCSRV\\TEMP\\SampleSubmission) and consume all available disk space, causing a denial of service condition.
