Technical Details of CVE-2023-1092

This section will delve deeper into the technical aspects of the vulnerability, including its description, affected systems, and exploitation mechanism.

Vulnerability Description

The OAuth Single Sign On Free, Standard, Premium, and Enterprise WordPress plugins are vulnerable to CSRF attacks during the deletion of Identity Providers, as they lack necessary CSRF checks. This oversight enables attackers to manipulate logged-in admins into unwittingly deleting IdPs.

Affected Systems and Versions

The vulnerability impacts the following MiniOrange OAuth Single Sign On WordPress plugins:

OAuth Single Sign On Free before 6.24.2
OAuth Single Sign On Standard before 28.4.9
OAuth Single Sign On Premium before 38.4.9
OAuth Single Sign On Enterprise before 48.4.9

Exploitation Mechanism

By exploiting the absence of CSRF protections during the deletion of IdPs, threat actors can craft malicious requests that, when executed by authenticated admins, trigger the unintended deletion of Identity Providers within the affected WordPress plugins.

Mitigation and Prevention

To address and prevent the exploitation of CVE-2023-1092, immediate steps, long-term security practices, and the importance of patching and updates are crucial considerations.

Immediate Steps to Take

Administrators should promptly update the affected MiniOrange OAuth Single Sign On plugins to versions that include CSRF checks for IdP deletions.
Monitor for any unauthorized deletions or suspicious activities related to Identity Providers within the WordPress plugins.

Long-Term Security Practices

Implement robust security measures, including regular audits of plugin configurations, user access controls, and CSRF protections, to mitigate similar vulnerabilities in the future.

Patching and Updates

Regularly apply security patches and updates released by plugin developers to ensure that known vulnerabilities, such as the CSRF flaw in this case, are addressed promptly and effectively.
