CVE-2025-58895: Integro Path Traversal Vulnerability

CVE-2025-58895 Overview

CVE-2025-58895 is a Local File Inclusion (LFI) vulnerability in the AncoraThemes Integro WordPress theme. The vulnerability stems from improper control of filename parameters used in PHP include/require statements, which can allow attackers to include arbitrary local files from the server. This type of vulnerability, classified under CWE-98, occurs when user-controlled input is not properly sanitized before being passed to file inclusion functions.

Critical Impact

Successful exploitation could allow attackers to read sensitive configuration files, access credentials, or potentially achieve remote code execution by chaining with other techniques such as log poisoning or PHP filter chains.

Affected Products

• AncoraThemes Integro WordPress Theme versions up to and including 1.8.0

Technical Details for CVE-2025-58895

Vulnerability Analysis

The Integro WordPress theme by AncoraThemes contains a Local File Inclusion vulnerability that allows unauthenticated attackers to include arbitrary files from the target server. The vulnerability exists due to insufficient input validation on filename parameters that are subsequently used in PHP include() or require() statements.

This vulnerability poses a significant risk because it can be exploited remotely without authentication. Although the attack requires certain conditions to be met (reflected in the high attack complexity), successful exploitation can result in complete compromise of confidentiality, integrity, and availability of the affected WordPress installation.

Local File Inclusion vulnerabilities in WordPress themes are particularly dangerous because they can expose sensitive files such as wp-config.php which contains database credentials, authentication keys, and other critical configuration data.

Root Cause

The root cause of this vulnerability is the improper control of filename parameters in PHP include/require statements. The Integro theme fails to properly sanitize or validate user-supplied input before using it in file path operations. This allows attackers to manipulate the file path using directory traversal sequences (such as ../) to access files outside the intended directory scope.

CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program) specifically describes this pattern where PHP applications allow external input to influence the file that gets included, leading to potential arbitrary file read or code execution.

Attack Vector

The attack vector is network-based, allowing remote attackers to exploit this vulnerability without requiring local access to the target system. The attack does not require authentication or user interaction, though the high attack complexity indicates that specific conditions must be met for successful exploitation.

Attackers typically exploit LFI vulnerabilities by crafting malicious HTTP requests that include directory traversal sequences in vulnerable parameters. These requests aim to include sensitive system files or configuration files that can reveal credentials, API keys, or other sensitive information that can be used for further attacks.

Detection Methods for CVE-2025-58895

Indicators of Compromise

• HTTP requests containing directory traversal sequences such as ../, ..%2f, or %2e%2e/ targeting theme-related endpoints
• Requests attempting to access sensitive files like /etc/passwd, wp-config.php, or .htaccess through theme parameters
• Unusual file access patterns in web server logs involving the Integro theme directory
• Error messages in PHP logs indicating failed file inclusion attempts or path manipulation

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block path traversal patterns in HTTP requests
• Monitor web server access logs for requests containing ../ sequences or encoded variants targeting the /wp-content/themes/integro/ directory
• Deploy file integrity monitoring to detect unauthorized access to sensitive configuration files
• Use intrusion detection systems (IDS) with signatures for LFI attack patterns

Monitoring Recommendations

• Enable verbose logging for the WordPress installation and review logs for anomalous file access attempts
• Set up alerts for requests to the Integro theme endpoints that contain path manipulation characters
• Monitor for spikes in 404 or 500 errors that may indicate exploitation attempts
• Implement real-time log analysis to detect directory traversal attack patterns

How to Mitigate CVE-2025-58895

Immediate Actions Required

• Update the Integro WordPress theme to a patched version if available from AncoraThemes
• If no patch is available, consider temporarily disabling or removing the Integro theme and switching to an alternative
• Review web server access logs for evidence of exploitation attempts
• Implement WAF rules to block path traversal attacks targeting WordPress themes
• Restrict file permissions on sensitive configuration files to minimize potential impact

Patch Information

No specific patch information is available at this time. Organizations should monitor the AncoraThemes website and WordPress theme repository for security updates. The Patchstack Integro Theme Vulnerability advisory may contain updated remediation guidance.

Workarounds

• Deploy a Web Application Firewall with rules configured to block directory traversal patterns in all HTTP parameters
• Implement PHP open_basedir restrictions to limit file inclusion to specific directories
• Use ModSecurity or similar WAF with OWASP Core Rule Set to detect and block LFI attempts
• Consider using a WordPress security plugin that provides virtual patching capabilities

# Apache ModSecurity configuration to block path traversal attempts
SecRule REQUEST_URI|ARGS|ARGS_NAMES "@rx (\.\./|\.\.%2f|%2e%2e/|%2e%2e%2f)" \
    "id:1001,phase:1,deny,status:403,msg:'Path Traversal Attack Detected'"

# PHP open_basedir restriction in php.ini or .htaccess
# php_value open_basedir /var/www/html:/tmp
