The Event Tickets and Registration plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'ajax_ticket_delete' function in all versions up to, and including, 5.19.1.1. This vulnerability allows authenticated attackers, with Contributor-level access and above, to delete arbitrary attendee tickets. The CVSS score for this vulnerability is 5.3, categorizing it as medium severity. The real-world risk context indicates that this weakness can lead to significant data loss if exploited, particularly in environments where attendee management is crucial.
With the attack vector being network and the attack complexity classified as low, organizations utilizing this plugin must assess their exposure. The urgency for defenders is clear: organizations should address this in priority patch cycle to prevent potential exploitation.
Currently, there is no known public exploit or proof of concept associated with this vulnerability, but the absence of such does not diminish its potential impact. Organizations should not underestimate the chance of exploitation, especially given the low privileges required for attacking.
Risk to organizations includes the unauthorized deletion of attendee data, which could lead to operational disruptions and loss of customer trust. Therefore, it is imperative for users of the Event Tickets and Registration plugin to implement the necessary updates as soon as possible.
Vulnerability Details
The Event Tickets and Registration plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'ajax_ticket_delete' function in all versions up to, and including, 5.19.1.1. This vulnerability allows authenticated attackers, with Contributor-level access and above, to delete arbitrary attendee tickets.
The CVSS score for this vulnerability is 5.3, indicating a medium severity level. The attack vector is network-based, and the attack complexity is low, which means attackers could exploit this vulnerability with relative ease. The privileges required are none, and user interaction is not necessary for exploitation. The impact on integrity is low, while confidentiality and availability impacts are none.
Technical Analysis
The root cause of this vulnerability stems from a missing capability check, which is a common oversight in web application design. Attackers may leverage this weakness to execute unauthorized actions, specifically the deletion of attendee tickets, which can disrupt event management and lead to a loss of critical data.
The attack vector is network-based, meaning that an attacker can exploit the vulnerability remotely without needing physical access to the server. The attack complexity is low, indicating that it does not require sophisticated skills or resources to exploit this vulnerability. Additionally, no user interaction is required, which enhances the likelihood of successful exploitation.
The impact on confidentiality is none, as the vulnerability does not allow unauthorized access to sensitive information. However, the integrity impact is low due to the possibility of unauthorized deletion of data. There is no impact on availability as the system remains operational.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is significant. Organizations utilizing the Event Tickets and Registration plugin may face unauthorized data deletion by authenticated users, which can disrupt operations and lead to reputational damage. The blast radius potential is particularly concerning for businesses that rely on this plugin for event management.
Given the medium CVSS score and the potential for exploitation, organizations should prioritize remediation efforts based on their risk tolerance and operational impact. The urgency for addressing this vulnerability is categorized as medium, aligning with the CVSS score and the fact that it could affect multiple users within an organization.
Organizations should prioritize patching immediately. Failure to address this vulnerability could lead to unauthorized access and manipulation of sensitive attendee data, resulting in significant operational and financial repercussions.
