DESCRIPTION:
Multiple vulnerabilities have been reported in RealNetworks Helix
Server, which can be exploited by malicious, local users to disclose
sensitive information and by malicious people to conduct cross-site
scripting attacks, cause a DoS (Denial of Service), or compromise a
vulnerable system.

1) The administrative and user credentials are insecurely stored in
the flat file database (\Program Files\Real\Helix
Server\adm_b_db\users\), which can be exploited by local users to
disclose the clear text passwords.

2) An error in the SNMP Master Agent process (master.exe) can be
exploited to terminate the service by establishing and immediately
closing a TCP connection on port 705.

3) An input validation error when processing the "DisplayString" of
SNMP object idenfiers can be exploited to cause an unhandled
exception and terminate the SNMP Master Agent service (master.exe)
via a specially crafted "Open-PDU" request sent to TCP port 705.

4) An unspecified error during rn5auth credential parsing can be
exploited to cause a buffer overflow.

Successful exploitation of this vulnerability may allow execution of
arbitrary code.

5) Certain unspecified input is not properly sanitised before being
returned to the user. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site.

6) An error when handling certain malformed URLs can be exploited to
crash the server process, but requires conducting a successful CSRF
(cross-site request forgery) attack against an administrative user.

The vulnerabilities are reported in version 14.2.0.212. Other
versions may also be affected.

SOLUTION:
Update to version 14.3.x.

Research (MSVR).
