Titel:	WordPress Ad Inserter Plugin < 2.4.22 Remote Code Execution Vulnerability
Zusammenfassung:	The WordPress plugin Ad Inserter is prone to an authenticated remote code execution vulnerability.
Beschreibung:	Summary: The WordPress plugin Ad Inserter is prone to an authenticated remote code execution vulnerability. Vulnerability Insight: The vulnerability stems from the use of the check_admin_referer() for authorization, when it was specifically designed to protect WordPress sites against cross-site request forgery (CSRF) exploits using nonces - one-time tokens used for blocking expired and repeated requests. Authenticated attackers who get their hands on a nonce can bypass the authorization checks powered by the check_admin_referer() function to access the debug mode provided by the Ad Inserter plugin. Once the attacker has a nonce at his disposal, he can immediately trigger the debugging feature and, even more dangerous, exploit the ad preview feature by sending a malicious payload containing arbitrary PHP code. Vulnerability Impact: Successful exploitation would allow authenticated users (Subscribers and above) to execute arbitrary PHP code on websites using the plugin. Affected Software/OS: WordPress Ad Inserter plugin before version 2.4.22. Solution: Update to version 2.4.22 or later. CVSS Score: 9.0 CVSS Vector: AV:N/AC:L/Au:S/C:C/I:C/A:C
