Buffer overflow in BRS WebWeaver 1.06 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an HTTP request with a long User-Agent header.
BRW WebWeaver 1.03 allows remote attackers to obtain sensitive server environment information via a URL request for testcgi.exe, which lists the values of environment variables and the current working directory.
BRS WebWeaver Web Server 1.01 allows remote attackers to bypass password protections for files and directories via an HTTP request containing a "/./" sequence.
