CVE-2022-0952 is a high-severity vulnerability affecting the Sitemap by click5 WordPress plugin versions prior to 1.0.36. This vulnerability allows unauthenticated attackers to exploit the absence of authorization and CSRF checks when updating options via a REST endpoint. The flaw permits attackers to modify key blog options such as users_can_register and default_role, which can lead to the creation of a new admin account and complete takeover of the blog.
The CVSS score for this vulnerability is 8.8, indicating a high severity level. With a low attack complexity and no privileges required, this vulnerability represents a serious risk for organizations utilizing this plugin. The impact on confidentiality, integrity, and availability is high, as attackers can gain unauthorized access and manipulate critical settings.
Organizations using the Sitemap plugin should prioritize patching to version 1.0.36 or later to address this vulnerability. The potential for exploitation is significant, particularly as the CVE has been acknowledged in threat intelligence databases, underscoring the urgency for remediation.
Immediate action is crucial. Organizations must ensure that all instances of the Sitemap by click5 plugin are updated to mitigate the risk of unauthorized administrative control. Monitoring for unusual activities relating to the plugin should also be implemented to detect any attempts of exploitation.
Vulnerability Details
The vulnerability is characterized by the lack of appropriate authorization and CSRF checks within the Sitemap by click5 WordPress plugin before version 1.0.36. This oversight allows attackers to update arbitrary options without authentication, thereby compromising the security posture of any WordPress site utilizing the plugin.
The vulnerability falls under the CWE classifications of CWE-352 (Cross-Site Request Forgery) and CWE-862 (Missing Authorization). This classification highlights the critical nature of the vulnerability, as it affects user permissions and the ability to control site functionality.
Technical Analysis
The root cause of this vulnerability is the lack of adequate checks within the REST endpoint of the Sitemap plugin. Attackers can exploit this flaw by sending crafted requests to the endpoint, changing settings that impact user registration and roles without needing any prior authentication.
The attack vector is network-based, with a low attack complexity since no special privileges are required. User interaction is necessary, as the attacker must entice the victim to perform an action that results in the malicious request being executed.
The confidentiality, integrity, and availability impacts are all high. This means that an attacker can not only access sensitive configuration data but also alter critical settings that could lead to a complete compromise of the site.
Risk & Impact Analysis
The risk to organizations includes unauthorized access to administrative controls, which can lead to the modification of user roles and settings. The potential for an attacker to create administrative accounts poses a significant threat to the security of the site.
Given the high CVSS score and the ease of exploitation, organizations must act swiftly to apply patches. The urgency for remediation is high, as failure to do so could result in catastrophic breaches and data loss.
