  • Resolved marikamitsos


    Hello and thank you for an excellent plugin,
    We use SB Uploader v3.3
    Two days ago we received an email from our provider stating:

    This is a courtesy notice that we have found and corrected exploitable timthumb.php file on your account While we have corrected these files, we do recommend you ensure all potential exploits are corrected on your account. This is best done by updating all scripts, plugins, modules and themes on your account to the latest version.

    The timthumb.php file is a script commonly used in WordPress’s (and other software’s) themes and plugins to resize images. The exploit allows an attacker to arbitrarily upload and create files and/or folders on your account, which can then be used for a number of malicious tasks, including but not limited to defacement, browser high-jacking and infection, data harvesting and more. After a site has been exploited, it may lead to becoming labeled a “Malicious Website” by Google or other security authorities.

    Any timthumb.php file below version 1.35, but above version 1.09 is considered vulnerable. To prevent being compromised, we advise you update all instances of timthumb.php to version 2.0, or patch the existing vulnerable files. Note that patching the files requires more in-depth knowledge of the PHP scripting language.

    The updated version of timthumb.php can be found here:

    We have automatically patched the files for you:

    Additional information regarding the compromise can be found at the following two websites, as well as others; note that all external websites in this email are for your reference only.

    As stated above the risk is only temporarily fixed by patching the file.
    Can you please look into it and update your files?

    Thanks again for your excellent plugin and time,

    Hey. Sorry about the delay in response. This forum doesn’t notify the plugin author when a new topic is created for a plugin. Either way the TimThumb issue is sorted now. It hit the internet hard a few months back but it’s all safe now.
