Scanning for PHP vulnerabilities with Pixy
Pixy is a source
code scanner for PHP 4 that tries to detect two major types of web
application vulnerabilities. Cross-site
scripting (XSS) and SQL injection are two
of the most commonly reported security problems in web applications; any
help in detecting and fixing them is welcome. In addition, for those who
want to try before they install, the project offers a web
interface to upload PHP code for XSS checking.
Pixy is a java program written by folks at the Secure Systems Lab at the
Vienna University of Technology. It is roughly a year old, with at least
one vulnerability
report attributed to it. The project homepage has extensive documentation
that will get the impatient going quickly but also satisfy the curiosity
of those interested in the guts of the tool.
Once you get past the "quick start", the Pixy documentation guides you
through the concept of "tainted" values, which underly both XSS and SQL
injection vulnerabilities. The basic idea is that unfiltered input can
enter the program in various ways, which is considered to be a tainted
value. In order to determine if the tainted value is used in a way that
could be exploited, you must follow the data through assignments and
function calls. If the data is then used in a way that could cause an XSS
(via echo() for example), Pixy will flag it. Similarly, if it is
used in a mysql_query(), a possible SQL injection will be flagged.
Using htmlentities() on data that is eventually output, will
remove the taint on that data for the purposes of XSS analysis. Using
addslashes() on arguments to SQL queries, changes their status to
"weakly tainted", which means they are not a problem when used inside
single quotes in the query, but are still dangerous when just interpolated
into the string.
The program produces two kinds of output, a textual report that lists the
line numbers as well as output that can be used with graphviz. The graphical output shows
a dependency graph describing the flow from the taint source to the
dangerous use.
Pixy is geared towards the most common usage of PHP and currently only
analyzes PHP 4. If a program uses its own, specialized filtering that is
even more cautious than the PHP built-ins, Pixy will not see that filtering
and will still consider the data to be tainted. In addition, checking for
SQL injection in any database other than MySQL seems to be lacking.
There are endless arguments about the PHP language and whether its
constructs and practices foster secure programs, but it is clear that many,
if not most, PHP projects have had security problems along the way.
Removing XSS and SQL injection problems would take care of a significant
fraction of the problems reported daily on BugTraq. Anyone working with
PHP code, especially when using MySQL via the mysql_query() call,
should seriously consider running Pixy while giving a careful look at
anything suspicious that it reports.

Windows Vista - 6 Month Vulnerability Report
Jeff Jones has updated
his report on security in Windows Vista vs. Linux and MacOSX for a 6 month period. LWN analyzes the original 90 day report
in this week's issue (subscribers only). He has changed his methodology
somewhat, this time around, to try and address some concerns expressed over
the original report.
" The results of the analysis show that Windows Vista continues to show a trend of fewer total and fewer High severity vulnerabilities at the 6 month mark compared to its predecessor product Windows XP (which did not benefit from the SDL) and compared to other modern competitive workstation OSes (which also did not benefit from an SDL-like process).
If you share the opinion that Windows and applications ported to Windows get a higher level of researcher scrutiny than other OSes, then the 6-month results are even more positive. If you don't share that opinion, then they still stand on their own ..."

apache: multiple vulnerabilities

CVE-2006-5752
|
| Created: | June 27, 2007 |
Updated: | February 18, 2008 |
| Description: |
The Apache HTTP Server did not verify that a process was an Apache child
process before sending it signals. A local attacker who has the ability to
run scripts on the Apache HTTP Server could manipulate the scoreboard and
cause arbitrary processes to be terminated, which could lead to a denial of
service. (CVE-2007-3304)
A flaw was found in the Apache HTTP Server mod_status module. Sites with
the server-status page publicly accessible and ExtendedStatus enabled were
vulnerable to a cross-site scripting attack. On Red Hat Enterprise Linux
the server-status page is not enabled by default and it is best practice to
not make this publicly available. (CVE-2006-5752) |

| Description: |
Konqueror 3.5.5 does not properly parse HTML comments, which allows remote
attackers to conduct cross-site scripting (XSS) attacks and bypass some XSS
protection schemes by embedding certain HTML tags within a comment, a
related issue to CVE-2007-0478. |

CVE #(s): | CVE-2007-1357

Updated: | November 14, 2007 |
| Description: |
The atalk_sum_skb function in AppleTalk for Linux kernel 2.6.x before
2.6.21, and possibly 2.4.x, allows remote attackers to cause a denial of
service (crash) via an AppleTalk frame that is shorter than the specified
length, which triggers a BUG_ON call when an attempt is made to perform a
checksum. |

CVE #(s): | CVE-2006-5749
CVE-2006-4814
CVE-2006-6106
|
| Created: | January 5, 2007 |
Updated: | May 7, 2008 |
| Description: |
A security issue has been reported in Linux kernel due to an error in
drivers/isdn/i4l/isdn_ppp.c as the "isdn_ppp_ccp_reset_alloc_state()"
function never initializes an event timer before scheduling it with the
"add_timer()" function.
The mincore function in the kernel does not properly lock access to user
space, which has unspecified impact and attack vectors, possibly related to
a deadlock.
Another vulnerability has been reported in Linux kernel caused by a
boundary error within the handling of incoming CAPI messages in
net/bluetooth/cmtp/capi.c. This can be exploited to overwrite certain
Kernel data structures. |

CVE-2007-1000

| Created: | March 15, 2007 |
Updated: | November 14, 2007 |
| Description: |
The Linux kernel has a boundary error problem with the
Omnikey CardMan 4040 driver read and write functions. This can be used
to cause a buffer overflow and possible execution or arbitrary code with
kernel privileges.
The ipv6_getsockopt_sticky function in
net/ipv6/ipv6_sockglue.c is vulnerable to a NULL pointer dereference.
Local users can use this to crash the kernel or to disclose kernel
memory. |

| Description: |
Linux kernel versions from 2.6.9 to 2.6.20 have a denial of service
vulnerability. A remote attacker can cause the key_alloc_serial
function's key serial number collision avoidance code to have a
null dereference, resulting in a crash. |

| Description: |
Sridhar Samudrala discovered a local denial of service vulnerability
in the handling of SCTP sockets. By opening such a socket with a
special SO_LINGER value, a local attacker could exploit this to crash
the kernel. (CVE-2006-4535)
Kirill Korotaev discovered that the ELF loader on the ia64 and sparc
platforms did not sufficiently verify the memory layout. By attempting
to execute a specially crafted executable, a local user could exploit
this to crash the kernel. (CVE-2006-4538) |

| Description: |
The netlink protocol has an infinite recursion bug that allows users to
cause a kernel crash. Also the IPv6 protocol allows remote attackers to
cause a denial of service via crafted IPv6 type 0 route headers
(IPV6_RTHDR_TYPE_0) that create network amplification between two routers. |

The ftdi_sio driver (usb/serial/ftdi_sio.c) in Linux kernel 2.6.x up to
2.6.17, and possibly later versions, allows local users to cause a denial
of service (memory consumption) by writing more data to the serial port
than the driver can handle, which causes the data to be queued. |
