CVE-2025-68015: Event Tickets with Scanner RCE Flaw

CVE-2025-68015 Overview

CVE-2025-68015 is a Code Injection vulnerability affecting the Vollstart Event Tickets with Ticket Scanner WordPress plugin. This vulnerability allows attackers to inject and execute arbitrary code through improper control of code generation (CWE-94). The flaw enables Remote Code Execution (RCE), potentially allowing attackers to fully compromise WordPress installations running vulnerable versions of this plugin.

Critical Impact

This Code Injection vulnerability in the Event Tickets with Ticket Scanner WordPress plugin could allow attackers to execute arbitrary code on affected servers, potentially leading to complete site takeover, data theft, and further lateral movement within the hosting environment.

Affected Products

• Event Tickets with Ticket Scanner plugin versions through <= 2.8.3
• WordPress installations using the vulnerable plugin
• Web servers hosting affected WordPress sites

Technical Details for CVE-2025-68015

Vulnerability Analysis

This vulnerability stems from improper control of code generation within the Event Tickets with Ticket Scanner WordPress plugin. The plugin fails to adequately sanitize or validate user-supplied input before incorporating it into dynamically generated code, enabling attackers to inject malicious code that gets executed by the server.

Code Injection vulnerabilities of this nature are particularly dangerous in WordPress environments because they can be exploited remotely without requiring prior authentication in some cases. Once exploited, attackers gain the ability to execute arbitrary PHP code with the same privileges as the web server process, which typically has write access to the WordPress installation directory.

The vulnerability affects the plugin's core functionality related to event ticket processing. When malicious input is crafted and submitted to the vulnerable endpoint, the plugin processes this input without proper sanitization, allowing the injected code to be executed on the server.

Root Cause

The root cause of CVE-2025-68015 is the Improper Control of Generation of Code (CWE-94). The plugin fails to implement proper input validation and sanitization before using user-controlled data in code generation contexts. This allows attackers to break out of the intended data context and inject executable code statements.

Attack Vector

The attack vector for this vulnerability involves submitting specially crafted input to the vulnerable plugin endpoints. An attacker would need to identify the vulnerable input parameter and craft a payload that escapes the intended context and injects malicious PHP code.

The vulnerability can be exploited remotely through the WordPress web interface. Successful exploitation requires the attacker to identify installations running vulnerable versions of the Event Tickets with Ticket Scanner plugin and submit malicious requests to trigger code execution.

Detection Methods for CVE-2025-68015

Indicators of Compromise

• Unexpected PHP files created in the WordPress installation directory or uploads folder
• Suspicious outbound network connections from the web server
• Unusual process execution by the web server user (e.g., www-data or apache)
• Modified plugin files or unexpected code additions to existing PHP files
• Web server logs showing unusual POST requests to plugin endpoints with encoded payloads

Detection Strategies

• Monitor web application firewall (WAF) logs for code injection patterns targeting WordPress plugins
• Implement file integrity monitoring on WordPress core files and plugin directories
• Deploy endpoint detection solutions capable of identifying malicious PHP execution patterns
• Review access logs for suspicious requests to /wp-content/plugins/event-tickets-with-ticket-scanner/ endpoints

Monitoring Recommendations

• Enable verbose logging for WordPress and the web server to capture detailed request information
• Configure alerts for new file creation within the WordPress directory structure
• Monitor for unusual database queries that may indicate post-exploitation activity
• Set up network monitoring to detect command-and-control communications from compromised servers

How to Mitigate CVE-2025-68015

Immediate Actions Required

• Audit WordPress installations for the Event Tickets with Ticket Scanner plugin and identify vulnerable versions (<= 2.8.3)
• Temporarily disable the plugin if an immediate update is not available
• Implement WAF rules to block known code injection patterns targeting this vulnerability
• Review server logs for evidence of exploitation attempts

Patch Information

Organizations should update the Event Tickets with Ticket Scanner plugin to the latest available version that addresses this vulnerability. Check the Patchstack Vulnerability Summary for the most current patch information and remediation guidance from the vendor.

Workarounds

• Disable the Event Tickets with Ticket Scanner plugin until a patch can be applied
• Implement strict input validation at the web application firewall level
• Restrict access to WordPress admin and plugin endpoints using IP allowlisting
• Consider using WordPress security plugins that provide virtual patching capabilities
