It can be exploited by "Unrestricted Upload of File" (Arbitrary File Uploading) attacks. With a specially crafted request, a remote attacker can include arbitrary files from the targeted host or from a remote or local host . This may allow disclosing file contents or executing files like PHP scripts. Such attacks are limited due to the script only calling files already on the target host. *(2.1)* The code flaw occurs at "thumb.php?" page with "src" parameters. *References:* http://tetraph.com/security/unrestricted-upload-of-file-arbitrary/wordpress-daily-edition-theme-v1-6-2-unrestricted-upload-of-file-security-vulnerabilities/ http://securityrelated.blogspot.com/2015/03/wordpress-daily-edition-theme-v162.html http://www.inzeed.com/kaleidoscope/computer-web-security/wordpress-daily-edition-theme-v1-6-2-unrestricted-upload-of-file-security-vulnerabilities/ http://diebiyi.com/articles/%E5%AE%89%E5%85%A8/wordpress-daily-edition-theme-v1-6-2-unrestricted-upload-of-file-security-vulnerabilities/ https://itswift.wordpress.com/2015/03/07/wordpress-daily-edition-theme-v1-6-2-unrestricted-upload-of-file-security-vulnerabilities/ http://seclists.org/fulldisclosure/2015/Mar/4 http://packetstormsecurity.com/files/130653/Webshop-Hun-1.062S-Directory-Traversal.html -- Wang Jing, Division of Mathematical Sciences (MAS), School of Physical and Mathematical Sciences (SPMS), Nanyang Technological University (NTU), Singapore. http://www.tetraph.com/wangjing/ https://plus.google.com/u/0/+JingWang-tetraph-justqdjing/posts
