Synopsis :

The remote media streaming server is affected by multiple
vulnerabilities.

Description :

According to its banner, the remote host is running version 14.x of
RealNetworks Helix Server / Helix Mobile Server. Such versions are
potentially affected by multiple vulnerabilities :

- Administrative and user credentials are insecurely
stored in a flat file database. This file may be
accessed by local users to disclose passwords stored in
clear text. (CVE-2012-1923)

- A buffer overflow exists in the code that parses
authentication credentials. It may be possible for a
remote attacker to exploit this issue and execute
arbitrary code. (CVE-2012-0942)

- Multiple unspecified cross-site scripting
vulnerabilities. (CVE-2012-1984)

- A specially crafted malformed URL can cause the server
process to crash if opened by an administrator.
(CVE-2012-1985)

- Establishing and immediately closing a TCP connection on
port 705 can cause the SNMP Master Agent to crash.
(CVE-2012-2267)

- A specially crafted Open-PDU request sent to the SNMP
Master Agent can cause it to crash due to an unhandled
exception. (CVE-2012-2268)
