CVE-2025-52744: Inpersttion For Theme RCE Vulnerability

CVE-2025-52744 Overview

CVE-2025-52744 is a Code Injection vulnerability affecting the Inpersttion For Theme WordPress plugin (err-our-team). This improper control of code generation vulnerability allows attackers to inject and execute arbitrary code within the context of the vulnerable WordPress installation. The vulnerability stems from insufficient input validation and sanitization, enabling malicious actors to execute unauthorized code on affected systems.

Critical Impact

Successful exploitation allows attackers to inject arbitrary code, potentially leading to complete site compromise, data theft, and further lateral movement within the hosting infrastructure.

Affected Products

• Inpersttion For Theme WordPress Plugin version 1.0 and earlier
• WordPress installations running the err-our-team plugin

Technical Details for CVE-2025-52744

Vulnerability Analysis

This vulnerability is classified under CWE-94 (Improper Control of Generation of Code), commonly known as Code Injection. The Inpersttion For Theme plugin fails to properly validate and sanitize user-supplied input before incorporating it into dynamically generated code. This architectural weakness creates a direct pathway for attackers to inject malicious code that will be executed by the server.

The network-accessible attack vector requires low-privilege authentication to exploit, meaning an attacker needs some level of authenticated access to the WordPress installation. However, once authenticated, no user interaction is required to trigger the vulnerability, making it readily exploitable in real-world scenarios.

Root Cause

The root cause of CVE-2025-52744 lies in the plugin's failure to implement proper input validation and output encoding. The plugin accepts user-controlled data and incorporates it directly into code execution pathways without adequate sanitization. This violates the principle of treating all user input as untrusted and enables code injection attacks.

Attack Vector

The attack is conducted over the network against WordPress installations running the vulnerable plugin. An authenticated attacker with low privileges can craft malicious input designed to break out of the intended data context and inject executable code. The injected code runs with the same privileges as the WordPress application, potentially allowing:

• Arbitrary file read/write operations
• Database access and manipulation
• Execution of system commands
• Installation of persistent backdoors
• Lateral movement to other hosted sites

The vulnerability mechanism involves improper handling of user input within the plugin's code generation logic. For detailed technical analysis, refer to the Patchstack Vulnerability Report.

Detection Methods for CVE-2025-52744

Indicators of Compromise

• Unexpected PHP files or modified plugin files within the err-our-team plugin directory
• Unusual outbound network connections originating from the web server
• Suspicious entries in WordPress or web server access logs showing encoded or obfuscated payloads targeting the plugin
• Creation of unauthorized administrator accounts or privilege escalations
• Unexpected scheduled tasks (cron jobs) or database modifications

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block code injection patterns targeting WordPress plugins
• Monitor file integrity for changes to the wp-content/plugins/err-our-team/ directory
• Review web server logs for suspicious POST requests containing PHP code fragments or encoded payloads
• Deploy endpoint detection solutions capable of identifying unauthorized code execution attempts

Monitoring Recommendations

• Enable verbose logging for WordPress and PHP to capture detailed request information
• Implement real-time alerting for new file creations within plugin directories
• Monitor for anomalous process spawning from web server processes (e.g., www-data or apache user)
• Establish baseline behavioral patterns and alert on deviations in database queries or file system activity

How to Mitigate CVE-2025-52744

Immediate Actions Required

• Immediately deactivate and remove the Inpersttion For Theme (err-our-team) plugin from all WordPress installations
• Audit WordPress installations for signs of compromise, including unauthorized users, modified files, and suspicious database entries
• Review and rotate all credentials associated with affected WordPress installations
• Implement network-level restrictions to limit access to WordPress admin interfaces

Patch Information

As of the last update, the vulnerability affects Inpersttion For Theme plugin version 1.0 and earlier. Site administrators should check for updated versions from the plugin developer. If no patch is available, the plugin should be removed entirely and replaced with a secure alternative. Monitor the Patchstack Vulnerability Report for updates on remediation guidance.

Workarounds

• Completely disable or remove the vulnerable plugin until a security patch is available
• Implement WAF rules to filter and block code injection payloads targeting the plugin
• Restrict plugin functionality through WordPress capabilities and role-based access controls
• Apply the principle of least privilege to WordPress user accounts to minimize the authenticated attack surface

# Disable the vulnerable plugin via WP-CLI
wp plugin deactivate err-our-team --path=/var/www/html/wordpress

# Remove the vulnerable plugin entirely
wp plugin delete err-our-team --path=/var/www/html/wordpress

# Verify plugin removal
wp plugin list --path=/var/www/html/wordpress | grep err-our-team
