Contributed by CVE reference:
- remote code injection via xml rpc library
It is recommended that all admins deactivate and remove the 'xmlrpc' module within administration-modules and additionaly remove /xmlrpc.php and and the /modules/xmlrpc folder completly from the filesystem.
The PostNuke CMS Development Team highly recommends to *not* use the xml rpc library until the maintainers  provide a secure solution. Once an updated version is available a modularized version will be provided for download as an additional module.
Note: The upcoming .760 release will not contain the xml rpc library.
The exploit has been originally found by James from GulfTech Security Research and was reported via security contact. Additionally the maintainers of the xml rpc library were contacted.
