Name of the Vulnerable Software and Affected Versions
Content Element Selector (ceselector) (affected versions not specified)
Description
The extension passes an attacker-controlled cookie directly to the
unserialize() function without safe processing. A remote, unauthenticated attacker can provide a crafted serialized payload to trigger PHP Object Injection, which allows for Remote Code Execution on the TYPO3 server. This issue occurs when the content element is configured with "Persistent Mode: Static" in the plugin settings. Over 294,700 TYPO3 CMS surfaces were indexed by FOFA in the past year.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
