Description
Redaxo CMS Mediapool Addon 5.5.1 and older contains an arbitrary file upload vulnerability that allows authenticated users to bypass file extension blacklist restrictions. Attackers with editor accounts can upload executable files by using obfuscated extensions like php71 or php53 to evade the blacklist filter and execute arbitrary code.
An arbitrary file upload vulnerability has been identified in the Redaxo CMS Mediapool Addon versions through 5.5.1. This vulnerability allows authenticated users, specifically those with editor accounts, to bypass file extension blacklist restrictions. The issue arises from the addon's use of a blacklist that incorrectly filters certain file extensions. Exploitation involves uploading executable files by using obfuscated extensions, such as php71 or php53, to evade the blacklist and execute arbitrary code.
Users are advised to update to Redaxo CMS version 5.6.0 and Mediapool Addon version 2.4.0, both of which contain the necessary fix.
