According to foreign media reports, Linux and other Open-source software has been a virus or hacker attacks are generally less likely. However, the recent discovery of a worm caused concern in the open source world. Because the target of this virus is the popular Web application taking tool (platform) PHP on Linux platform.
The worm exploits a vulnerability in PHP's XML-RPC component. You can launch an attack on a Web server.
It is reported that XML-RPC as a part of PHP, such as PostNuke, Drupal, B2evolution, Xoops, WordPress, Phpgroupware and TikiWiki and other products used. After the news of the Lupper worm, the developers of these components have been upgraded or patched packages have been introduced.
Because Linux and its open source application software security is relatively high, antivirus software vendors are not in time to warn the worm.
XML-RPC vulnerabilities were first discovered in June of this year, and a second security warning was reported in August. Because most users did not upgrade XML-RPC, the worm spread gradually.
