WordPress Security-parse error. not well formed- spam

This caught me by surprise when I ran across this information. There seems to be a exploit in some version of wordpress. The exploit from what I have seen is caused by users using a remote site to post to their blog.

view the blog content using google Reader or via curl will display the spam content
curl –user-agent “Googlebot/2.1″ http://blogurl.com

Such sites include windows live writer.
I would recommend taking a look at the wordpress users that are setup on your site . Verify that only approved users have administrative rights. also compare your existing files with the files from the installation zip from wordpress.com ..

The key file is xmlrpc.php
if you see this on line 27 , then you have a huge problem
$HTTP_RAW_POST_DATA = mysql_escape_string(trim($HTTP_RAW_POST_DATA));

Straight to the point

Possible error you may see

ALL: Disable SSLV2 -PCI Compliance

To disable SSLv2 server-wide add this in your ssl.conf:
SSLProtocol all -SSLv2
SSLCipherSuite ALL:!ADH:!LOW:!SSLv2:!EXP:+HIGH:+MEDIUM
or ALL:!ADH:!NULL:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:-LOW:+SSLv3:+TLSv1:-SSLv2:+EXP:+eNULL

Test using the following command via linux
openssl s_client -host (host-ip) -port 443 -verify -debug -ssl2

you can also try

curl –cipher SSLv2 domain.com:443

openssl s_client -connect domain:443 -state

openssl s_client -connect domain:443 -sslv2

*change (host-ip) with the domain name or the server ip address

if SSL2 is disable
You should see an output similar to this if its disabled:
verify depth is 0
CONNECTED(00000003)
4738:error:1407F0E5:SSL routines:SSL2_WRITE:ssl handshake failure:s2_pkt.c:429:
or
verify depth is 0
CONNECTED(00000003)
write:errno=104
=======================
enabling only strong ciphers in apache

Good tool to check SSL ciphers

Reference site

=========

Cpanel:
The SSLCipherSuite can be customized in cPanel/WHM 11.24 by going to WHM -> Service Configuration -> Apache Configuration -> Global Configuration. This is the place where you can disable SSL 2.0 support if you desire. Click the “more info” link on that page for more info.
