Cisco Security Advisory: Cisco 7600 Series Router Session Border Controller Denial of Service Vulnerability

As a workaround, configure an access control list (ACL) in the
signaling / media VLAN on the Route Processor (RP). The following
examples show how VLAN 140 is configured as the signaling / media
VLAN. A separate VLAN (VLAN 77) is configured as Fault Tolerance
(FT). An ACL is added to the signaling/media VLAN on the RP filtering
all TCP port 2000 packets to the alias IP address.

BT Home Flub: Pwnin the BT Home Hub (5) - exploiting IGDs remotely via UPnP

actually lead to UPnP being exploited remotely, even if the web admin
console is not visible from the Internet!

The following is a non-malicious proof-of-concept exploit which sets
up a port-forwarding rule from port 1337 on the WAN interface to port
445 on the internal IP address 192.168.1.64. Such IP address is the
first usable IP address reserved for clients connected to Speedtouch
and BT Home Hub routers. The exploit has been tested on BT Home Hub -
Firmware version 6.2.6.B. Just to make things clear, UPnP is enabled
by default on the BT Home Hub, just like most IGDs. If your Internet
gateway is a BT Home Hub, clicking on the following link should add a

RFC 2818 covers the requirements for matching CNs and subjectAltNames
in order to establish valid SSL connections. It first discusses CNs
that are for hostnames, and the rules for wildcards in this case.
The next paragraph in the RFC then discusses CNs that are IP
addresses:

'In some cases, the URI is specified as an IP address rather than a
hostname. In this case, the iPAddress subjectAltName must be present
in the certificate and must exactly match the IP in the URI.'

Cisco Security Advisory: Cisco IOS Software Network Time Protocol Packet Vulnerability

Workarounds
===========

There are no workarounds other than disabling NTP on the device. The
following mitigations have been identified for this vulnerability;
only packets destined for any configured IP address on the device can
exploit this vulnerability. Transit traffic will not exploit this
vulnerability.

Note: NTP peer authentication is not a workaround and is still a
vulnerable configuration.

Cisco Security Advisory: Cisco IOS Software Internet Group Management Protocol Denial of Service Vulnerability

=======

Internet Group Management Protocol (IGMP) is the protocol used by
hosts and adjacent routers to manage membership in IP multicast
groups. The IGMP version 3 protocol permits source-specific multicast
which allows hosts to specify the IP address of the multicast source.

A malformed IGMP packet can cause a vulnerable device to reload. This
vulnerability can only be exploited if the malformed IGMP packet is
received on an interface that has been enabled for IGMP version 3 and
Protocol Independent Multicast (PIM). The malformed IGMP packet

CVE: CVE-2010-2860

Finding:
The Celerra appliance's NFS server freely exports its "/" file system and
enforces access using a factory-defined list of authorized IP addresses.
The addresses found on a recent model are listed in the showmount example
below, however this list may differ depending on product version. The IP
addresses are intended for communication internal to the appliance, but are
still accepted from external sources. An attacker can mount this file system
by spoofing an authorized IP address.

PR07-40: Authentication Bypass, Passwords Leakage and SNMP Injection on 3Com AP 8760

What's important to note is that every time an "authenticated" URL is
accessed, there is _no_ authentication data being sent within HTTP
requests whatsoever. There are no passwords, or session IDs being
submitted at all within HTTP requests. Instead, the AP uses the
administrator's source IP address as authentication data.

This means that the authentication state relies on the false assumption
that post-authentication URLs won't be known by an attacker and that the
attacker and the administrator will _not_ share the same source IP
address. By simply accessing administrative URLs in a browser from _the

CORE-2008-0826 - Internet Explorer Security Zone restrictions bypass

There are some issues in the way IE enforces zone security policies when
an URI is specified in the UNC form (i.e.,
'\\MACHINE_NAME_OR_IP\PATH_TO_RESOURCE'). In this case, Internet
Explorer classifies as *Internet Zone* any UNC address pointing to an IP
address including '127.0.0.1'. As a result, any website (belonging to
any security zone) can address and redirect the navigation flow to files
stored in '\\127.0.0.1'.

If an attacker controlling a website finds a way to store HTML with any
valid scripting code the local file system of the visitor and then

listed game servers, asking each for its description. The client's parsing of
the servers' responses is vulnerable to a buffer overflow attack.

The client is designed to listen for incoming UDP packets from
master.corservers.com and from the game servers on port 27901, however it will
accept and parse UDP packets from any IP address even if the client did not
initiate a UDP conversation with that given IP address. As such, an attacker
can send a malformed UDP packet from any source IP address; they need not know
a valid game server's IP address to exploit this buffer overflow vulnerability.

When the client receives a UDP packet on port 27901 that specifies a server's

Cisco Security Advisory: Cisco IOS Software Mobile IP and Mobile IPv6 Vulnerabilities

Details
=======

Mobile IP is part of both IPv4 and IPv6 standards. Mobile IP allows a
host device to be identified by a single IP address even though the
device may move its physical point of attachment from one network to
another. Regardless of movement between different networks,
connectivity at the different points is achieved seamlessly without
user intervention. Roaming from a wired network to a wireless or
wide-area network is also possible.

Cisco Security Advisory: Cisco 10000, uBR10012, uBR7200 Series Devices IPC Vulnerability

used to mitigate this vulnerability. UDP port 1975 is a registered
port number that can be used by certain applications. However,
filtering all packets that are destined to UDP port 1975 may cause
some applications to malfunction. Therefore, access lists need to
explicitly deny UDP 1975 packets that are sent to any router
interface IP addresses and permit transit traffic. Such access lists
need to be applied on all interfaces to be effective. Since the IPC
channel uses addresses from the 127.0.0.0/8 range, it is also
necessary to filter packets that are sourced from or destined to this
range. An example is given below:
