AI risk analysis

Summary
This vulnerability allows unauthenticated attackers to bypass authentication by manipulating the X-Requested-With header, gaining access to admin endpoints and performing actions such as manipulating poll states and vote counts.
Exploitability
Exploitation is relatively straightforward as it requires sending a specific HTTP request with a base64-encoded path. Attackers must have network access to the target system.
Blast radius
If exploited, this vulnerability could lead to unauthorized access to sensitive admin functionalities, potentially impacting the integrity and confidentiality of the application data.
Detection
No reliable host or network indicator is derivable from the published description.
Prioritized remediation
Disable the AJAX dispatcher feature or restrict access to the affected endpoints by implementing proper authentication mechanisms.

NVD description

MaxSite CMS 109.5 and earlier contains an authentication bypass vulnerability in the AJAX dispatcher that allows unauthenticated attackers to access admin-gated endpoints by supplying any X-Requested-With header and requesting a base64-encoded path resolving to any *-ajax.php file in the codebase. Attackers can exploit this dispatcher bypass to reach privileged plugin endpoints without credentials, enabling actions such as manipulating poll states and vote counts, and amplifying the impact of any dangerous operation performed by admin-only ajax files across the plugin tree.
