TITLE:
3Com Wireless 8760 Access Point Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA32809

VERIFY ADVISORY:
http://secunia.com/advisories/32809/

CRITICAL:
Less critical

IMPACT:
Security Bypass, Cross Site Scripting, Exposure of system
information, Exposure of sensitive information

WHERE:
>From local network

OPERATING SYSTEM:
3Com Wireless 8760 Dual-Radio 11a/b/g PoE Access Point
http://secunia.com/advisories/product/19748/

DESCRIPTION:
Adrian Pastor has reported some vulnerabilities in 3Com Wireless 8760
Dual-Radio 11a/b/g PoE Access Point, which can be exploited by
malicious people to bypass certain security restrictions and disclose
sensitive information, and by malicious users to conduct script
insertion attacks.

1) The problem is that the authentication mechanism improperly
restricts access to administration pages. This can be exploited to
access restricted administration pages via HTTP requests originating
from the IP address of the logged-in administrator.

2) The problem is that sensitive information is included in HTTP
responses for e.g. the s_brief.htm and s.htm pages. This can be
exploited to e.g. disclose the administrator's password included in
hidden HTML form fields.

3) Input passed when setting the system name via SNMP requests is not
properly sanitised before being stored. This can be exploited to
inject arbitrary HTML and script code, which is executed in a user's
browser session in context of an affected site when the malicious
data is viewed.

Successful exploitation of this vulnerability requires that the
attacker has SNMP write privileges.

The vulnerabilities are reported in firmware version 2.1.13b05_sh.
Other versions may also be affected.

SOLUTION:
Restrict web interface and SNMP access.
