This vulnerability is classified with a CVSS score of 7.1, indicating significant risk potential. The vulnerability affects versions of the WP Simple Sitemap plugin from n/a through 0.2, which means all users of this plugin should be concerned about potential exploitation.
Organizations using the affected versions of WP Simple Sitemap are at risk of attackers exploiting this CSRF vulnerability. The attack vector is network-based with low complexity. Given the high severity rating, organizations should prioritize patching immediately.
As of now, there are no confirmed public exploits available, although the potential for exploitation exists. The urgency for organizations to address this vulnerability is underscored by its classification and the implications it has for stored XSS attacks.
The CSRF vulnerability could lead to unauthorized actions being performed on behalf of authenticated users, which can compromise sensitive data and user integrity. Organizations should assess their risk exposure and implement necessary updates to mitigate this threat.
Vulnerability Details
Cross-Site Request Forgery (CSRF) vulnerability in Jenst WP Simple Sitemap wp-simple-sitemap allows Stored XSS. This issue affects WP Simple Sitemap: from n/a through <= 0.2. The vulnerability is classified under CWE-352.
The CVSS score of 7.1 indicates a high severity level, and the scoring breakdown is as follows: Attack Vector: NETWORK, Attack Complexity: LOW, Privileges Required: NONE, User Interaction: REQUIRED, Scope: CHANGED, Confidentiality Impact: LOW, Integrity Impact: LOW, Availability Impact: LOW.
Technical Analysis
The root cause of the vulnerability lies in improper validation of requests, allowing attackers to manipulate user actions through crafted requests. The attack vector is network-based, meaning that the attack can be initiated remotely. User interaction is required for exploit execution, as the victim must be tricked into performing actions on a compromised site.
The complexity of the attack is low, as attackers can leverage social engineering techniques to exploit the vulnerability. The requirement for no privileges means that any user can potentially be a target, which broadens the attack surface. The impacts on confidentiality, integrity, and availability are classified as low, but the potential for stored XSS poses significant risks to user data.
Risk & Impact Analysis
Risk to organizations includes unauthorized actions taken on behalf of legitimate users, which could result in data exposure or manipulation. The potential blast radius is substantial, particularly for organizations with a large number of users who may be tricked into executing malicious actions.
Given that the vulnerability is classified as high severity, organizations should address it in their priority patch cycle. The presence of an exploitability score of 2.8 highlights the need for immediate action to prevent potential exploitation.
Organizations should also review their user training programs to educate users about the risks of CSRF attacks and the importance of verifying URL requests before interacting with web applications.
