CVE-2025-25162: Sports Rankings Path Traversal Flaw

CVE-2025-25162 Overview

CVE-2025-25162 is an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability affecting the WordPress plugin "Sports Rankings and Lists" developed by kutu62. This vulnerability allows attackers to perform Absolute Path Traversal attacks, potentially enabling unauthorized access to sensitive files outside the intended directory structure.

Path traversal vulnerabilities in WordPress plugins represent a significant security risk, as they can allow attackers to read arbitrary files from the server, including configuration files containing database credentials, WordPress secrets, and other sensitive information.

Critical Impact

Attackers can exploit this vulnerability to access files outside the plugin's designated directory, potentially exposing sensitive server configurations, WordPress credentials, and other critical system files.

Affected Products

• Sports Rankings and Lists WordPress Plugin versions through 1.0.2
• WordPress installations using the sports-rankings-lists plugin
• Web servers hosting affected WordPress instances

Technical Details for CVE-2025-25162

Vulnerability Analysis

This vulnerability is classified under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory), commonly known as Path Traversal or Directory Traversal. The Sports Rankings and Lists plugin fails to properly sanitize user-supplied input before using it to construct file paths, allowing attackers to use directory traversal sequences (such as ../) to access files outside the intended directory.

The vulnerability specifically enables Absolute Path Traversal, which means an attacker can potentially specify complete file system paths rather than being restricted to relative paths. This type of vulnerability is particularly dangerous because it bypasses directory restrictions entirely.

Root Cause

The root cause of this vulnerability lies in insufficient input validation and sanitization within the Sports Rankings and Lists plugin. When the plugin processes user-supplied file path parameters, it does not adequately filter or validate the input to prevent directory traversal sequences. This allows malicious actors to manipulate file paths and escape the plugin's intended directory boundaries.

Common contributing factors to path traversal vulnerabilities include:

• Missing or inadequate canonicalization of file paths
• Failure to validate that resolved paths remain within allowed directories
• Direct use of user input in file system operations without proper sanitization

Attack Vector

The attack vector for this vulnerability involves manipulating input parameters that are used to construct file paths within the plugin. An attacker can craft malicious requests containing path traversal sequences to navigate outside the plugin's directory structure.

For example, an attacker might attempt to access sensitive files such as /etc/passwd on Linux systems or WordPress configuration files like wp-config.php by injecting sequences like ../../../ into vulnerable parameters.

The vulnerability can be exploited remotely over the network by any user who can send requests to the WordPress installation running the vulnerable plugin.

Detection Methods for CVE-2025-25162

Indicators of Compromise

• Unusual file access patterns in web server logs, particularly requests containing ../ sequences
• Access attempts to sensitive files like /etc/passwd, wp-config.php, or .htaccess through plugin endpoints
• Error logs showing failed attempts to access files outside the WordPress installation directory
• Suspicious HTTP requests to the sports-rankings-lists plugin endpoints with encoded path traversal characters

Detection Strategies

• Monitor web application firewall (WAF) logs for path traversal patterns targeting the sports-rankings-lists plugin
• Implement intrusion detection rules to alert on requests containing common traversal sequences (../, ..%2f, %2e%2e/)
• Review WordPress plugin access logs for anomalous file read operations
• Deploy file integrity monitoring on critical configuration files

Monitoring Recommendations

• Enable verbose logging for WordPress and the web server to capture detailed request information
• Configure real-time alerting for path traversal pattern detection in security monitoring tools
• Regularly audit plugin file access patterns to establish baseline behavior
• Monitor for unexpected data exfiltration or large file transfers from the web server

How to Mitigate CVE-2025-25162

Immediate Actions Required

• Update the Sports Rankings and Lists plugin to a patched version when available
• If no patch is available, consider temporarily deactivating the plugin until a fix is released
• Implement web application firewall (WAF) rules to block path traversal attempts
• Restrict file system permissions to limit the impact of potential exploitation

Patch Information

As of the last update, versions through 1.0.2 of the Sports Rankings and Lists plugin remain affected. Website administrators should check the Patchstack Vulnerability Report for the latest information on available patches and remediation guidance.

Contact the plugin developer kutu62 for information about updated versions that address this vulnerability.

Workarounds

• Implement server-side input validation to reject requests containing path traversal sequences
• Use a web application firewall (WAF) to filter malicious requests before they reach WordPress
• Apply the principle of least privilege to the web server user, limiting access to only necessary directories
• Consider using WordPress security plugins that provide additional path validation and request filtering

# Apache mod_rewrite configuration to block path traversal attempts
# Add to .htaccess file in WordPress root directory
