DESCRIPTION:
Luigi Auriemma has discovered multiple vulnerabilities in some Cogent
products, which can be exploited by malicious users to disclose
potentially sensitive information and compromise a vulnerable system
and by malicious people to compromise a vulnerable system.

1) A boundary error when processing certain commands can be exploited
to cause a stack-based buffer overflow by e.g. sending specially
crafted "domain", "report_domain", "register_datahub", or "slave"
commands to TCP ports 4502 (plain text) or 4503 (SSL).

2) An input validation error in the webserver can be exploited to
disclose arbitrary files via directory traversal attacks.

3) An integer overflow error in the webserver when handling the HTTP
"Content-Length" header can be exploited to cause a heap-based buffer
overflow by sending specially crafted HTTP requests.

4) An error within the webserver when handling requests ending with
certain characters can be exploited to e.g. disclose the source code
of .ASP scripts by appending "+", "%20", or "%2e" to the requested
URL.

Vulnerabilities #2 through #4 may require valid credentials to the
internal webserver.

The vulnerabilities are reported in the following products:
* Cogent DataHub versions prior to 7.1.2 (confirmed in 7.1.1.63).
* OPC DataHub versions prior to 6.4.20.
* Cascade DataHub versions prior to 6.4.20.

SOLUTION:
Update to version 7.1.2 or 6.4.20.
