Access Control
the embedding of arbitrary remote images.
CVE-2011-1580
MediaWiki developer Happy-Melon discovered that the transwiki import
feature neglected to perform access control checks on form submission.
The transwiki import feature is disabled by default. If it is enabled,
it allows wiki pages to be copied from a remote wiki listed in
$wgImportSources. The issue means that any user can trigger such an
import to occur.

Correct. It is a completely flawed assumption.
In Unix, an open() of a file checks access permissions as
specified in the files inode. If someone wants access control
applied to a file, then he MUST do so using the permission in
the file inode.
Making assumptions about directory search and acces permissions
is plain stupid.

Improper validation of micro_httpd server permits multiple attacks
though this stateless server. Also, access control is defficient and
do not control access at all. Credentials are send in clear text so
"user" could get them easily.
Some fields and data are not filtered so XSS attacks and bofs can DoS

Black Hat Europe returns to Amsterdam from April 14 to April 17 with the
best lineup of security trainers and speakers anywhere on the European
continent. Tracks include Hardware and Embedded Devices, Reversing and
Malware, Client Wars and Application Security, as well as a focus on the
Enterprise for issues typically found in large enterprises, from databases,
access control, data management, centralized logging and policy management
all the way to routing and switching infrastructure.
The CFP closes February 1 with final selection expected by February 15,
2009. Papers can be submitted to:

I'm not sure if you can control some memory using other options in winsat.exe arguments to take advantage of this issue, and exploit it.
Even if the bug is exploitable, the User Access control present in vista, shows a message asking for privileges before execute it, the only advantage of this issue, I think that is the message asking for privileges, shows information about the process, and this is the information that the user have in mind to decide if accept or not, and if you execute a windows util, it asks for privileges, the information about WHO is asking for privileges, is a trusted windows util (winsat.exe, in system32) and then, if you can control the process, you can use this kind of bugs as way to trick the user to bypass the UAC and get admin.
This cloud-web application security workshop covers web applications in various virtual infrastructures, primarily focused on defense, compliance, and incident response. First, we'll identify applications as if they had already been attacked. Then, we'll come up with a risk management plan based on incident data, compliance/regulations, as well as data classifications. We'll look at full-knowledge verification using web server configuration and content files, in addition to runtime and source code verification. We'll go over the various implications of pen-testing cloud-web applications. This will include a thorough look at the strengths and weaknesses of web application firewalls and application hardening practices. Finally, we'll perform mock verifications and discuss partnering with application developers.
Applied Physical Security - Lockpicking and Safecracking
Instructor: datagram
Includes: 1 lockpicking kit, 1 handcuff key, 1 practice deadbolt, 1 practice padlock
This course focuses on learning and applying techniques of lockpicking, key bumping, impressioning, decoding, bypass, and safe cracking against a variety of real world locks and safes. Common lock designs are examined for various weaknesses that allow different methods of attack, some of which are extremely fast and easy to perform. High security locks will also be examined so attendees can learn to spot good locks from bad locks when shopping for access control devices.
DEEP KNOWLEDGE SEMINARS
Once again we are providing an additional day of deep knowledge seminars focused on addressing the growing corporate security issues in a small classroom environment that encourages discussion and interaction with the instructors. Here are a couple topics that have been preliminarily accepted for the Seminars:

Hi all,
Apparently there is some disagreement about this issue. I am providing more information to build a greater understanding about what is happening.
This problem is entirely contained within the query.php file. At the comment header of query.php it says: "The Big Query." Yes indeed this file produces a large query. This file is very disorganized and it was difficult to go though with a fine tooth comb, but I did and i found a flaw because of it. I was looking for SQL Injection, but broken access control will get me a CVE number.
Perhaps this URL provides more information:
http://localhost/wordpress/index.php/'wp-admin/
I urge everyone to make this get request and to print the $_SERVER['REQUEST_URI'] and $_SERVER['PHP_SELF'] variables.
You will see that wp-admin/ is at the end of these variables.

Doing it as dup() is indeed the way to go. /proc/*/fd/ already needs

CVE Name: N/A
Details
=======
The Cisco Physical Access Gateway is the primary means for the Cisco
Physical Access Control solution to connect door hardware, such as
locks and readers, to an IP network. Certain crafted TCP port 443
packets may cause a memory leak that could lead to a denial of
service (DoS) condition in the Cisco Physical Access Gateway. A TCP
three-way handshake is needed to exploit this vulnerability.
control-plane
service-policy input control-plane-policy
Note: Because SIP can use UDP as a transport protocol, it is possible
to spoof the source address of an IP packet, which may bypass access
control lists that permit communication to these ports from trusted
IP addresses.
In the preceding CoPP example, the access control entries (ACEs) that
match the potential exploit packets with the permit action cause these
packets to be discarded by the policy-map drop function, whereas
-- Netrw Reference Manual (``pi_netrw.txt'')
Although FTP communication is not encrypted and therefore open to
eavesdropping, if the access to the network is protected, a
credentials-based access control is meaningful, and the credentials must
be kept secret. For example, an FTP connection to a virtual Xen
instance on the same physical machine is secure; so is an FTP session
over a local ethernet segment secured against access from untrusted
parties.
code segments of running processes.
III. ANALYSIS
Exploitation allows an attacker to gain complete control of the affected
machine. The access control mechanisms under a default installation
allow restricted accounts to access the affected device drivers.
IV. DETECTION
iDefense has confirmed the existence of these vulnerabilities within

- ----------------
In the simplest scenarios, an attacker could use this flaw to inject
malicious versions of headers which are considered trusted. In certain
situations, headers are added to requests by the web server proxy module
which may be used to make decisions about authentication or access
control.
For instance, the WL-Proxy-Client-IP header is added to requests to
indicate to the application server which IP address the client used. If
the application server uses this to enforce IP-based access control
restrictions, then clearly this injection vulnerability could be used to
