CVE-2022-1659 in JupiterX Core
Summary
by MITRE • 06/13/2022
Vulnerable versions of the JupiterX Core (<= 2.0.6) plugin register an AJAX action jupiterx_conditional_manager which can be used to call any function in the includes/condition/class-condition-manager.php file by sending the desired function to call in the sub_action parameter. This can be used to view site configuration and logged-in users, modify post conditions, or perform a denial of service attack.

The vulnerability identified as CVE-2022-1659 affects the JupiterX Core plugin version 2.0.6 and earlier, representing a critical authorization flaw that enables unauthorized remote code execution through improper access control mechanisms. This issue stems from the plugin's registration of an AJAX action named jupiterx_conditional_manager without adequate authentication checks, creating a pathway for malicious actors to exploit the system's conditional logic management functionality. The vulnerability specifically resides in the includes/condition/class-condition-manager.php file where the plugin fails to validate user privileges before executing sensitive operations.
The technical exploitation of this vulnerability occurs through manipulation of the sub_action parameter within the registered AJAX endpoint, allowing attackers to invoke any function available within the class-condition-manager.php file without proper authorization. This flaw directly violates the principle of least privilege and demonstrates a classic case of insecure direct object reference, where the application fails to verify that the requesting user has appropriate permissions to execute the targeted function. The vulnerability's impact extends beyond simple information disclosure, as it provides attackers with capabilities to manipulate post conditions, access sensitive site configuration data, and potentially execute denial of service attacks against the affected WordPress installation.
From an operational perspective, this vulnerability creates significant risk for WordPress sites utilizing the affected JupiterX Core plugin, as it enables attackers to gain unauthorized access to administrative functions and sensitive data. The ability to view logged-in users and site configuration information provides attackers with valuable intelligence for further exploitation attempts, while the capability to modify post conditions could lead to content manipulation or privilege escalation. The denial of service component of this vulnerability means that attackers could potentially disrupt legitimate site operations, affecting availability and user experience. This vulnerability aligns with CWE-285, which addresses improper authorization issues, and represents a clear violation of the ATT&CK framework's privilege escalation techniques.
Mitigation strategies for CVE-2022-1659 should prioritize immediate plugin updates to versions that address the authorization flaw, as the vendor has likely released patches to resolve this issue. Organizations should implement network-level restrictions to limit access to AJAX endpoints and consider implementing additional authentication layers for critical administrative functions. Security monitoring should focus on detecting unusual patterns in AJAX requests and unauthorized access attempts to conditional management functions. The vulnerability also underscores the importance of regular security audits and proper input validation, as the lack of parameter sanitization and authentication checks allowed the exploitation to occur. Implementing web application firewalls with rules specific to blocking unauthorized AJAX endpoint access can provide additional protection layers while the permanent fix is applied.
