CVE-2025-68905: JNews Pay Writer LFI Vulnerability

CVE-2025-68905 Overview

CVE-2025-68905 is a Local File Inclusion (LFI) vulnerability affecting the JNews - Pay Writer WordPress plugin developed by jegtheme. The vulnerability stems from improper control of filename for include/require statements in PHP (CWE-98), allowing attackers to include local files on the server through manipulated input parameters.

This vulnerability affects the jnews-pay-writer plugin through version 11.0.0, potentially enabling attackers to read sensitive files, execute arbitrary PHP code if combined with other techniques, or extract configuration data from the WordPress installation.

Critical Impact
Attackers can leverage this Local File Inclusion vulnerability to read sensitive server files, potentially exposing database credentials, API keys, and other confidential configuration data from the WordPress installation.

Affected Products

JNews - Pay Writer WordPress Plugin versions through 11.0.0
WordPress installations using the jnews-pay-writer plugin

Technical Details for CVE-2025-68905

Vulnerability Analysis

This vulnerability is classified as Improper Control of Filename for Include/Require Statement in PHP Program, which allows PHP Local File Inclusion attacks. In PHP applications, the include(), require(), include_once(), and require_once() functions are used to incorporate external PHP files into the executing script. When user-controllable input is passed to these functions without proper validation or sanitization, attackers can manipulate the file path to include unintended local files.

The JNews - Pay Writer plugin fails to properly validate or sanitize user-supplied input before using it in file inclusion operations. This design flaw allows malicious actors to traverse directory structures and include arbitrary files from the server's filesystem.

Root Cause

The root cause of CVE-2025-68905 lies in insufficient input validation within the JNews - Pay Writer plugin. The vulnerable code path accepts user-controllable parameters that are subsequently used in PHP file inclusion statements without proper sanitization. This allows attackers to use directory traversal sequences (such as ../) or direct file paths to reference files outside the intended scope.

Common exploitation patterns for this type of vulnerability include:

Reading the WordPress wp-config.php file to extract database credentials
Accessing server configuration files like /etc/passwd on Linux systems
Including log files that may contain injected PHP code (log poisoning)
Reading plugin and theme source code to identify additional vulnerabilities

Attack Vector

The attack vector for this vulnerability involves sending crafted HTTP requests to the WordPress installation with manipulated parameters targeting the vulnerable file inclusion functionality in the JNews - Pay Writer plugin. An attacker would typically identify the vulnerable parameter and supply a path traversal sequence to include sensitive files.

For example, an attacker might manipulate a template or file path parameter to traverse out of the plugin directory and access files elsewhere on the server. When successful, the contents of the included file are either displayed to the attacker or executed as PHP code, depending on the file type and server configuration.

The vulnerability can be exploited remotely without authentication if the vulnerable endpoint is accessible to unauthenticated users. Technical details and proof-of-concept information may be available through the Patchstack Vulnerability Report.

Detection Methods for CVE-2025-68905

Indicators of Compromise

Unusual HTTP requests containing directory traversal patterns (../, ..%2f, %2e%2e/) targeting the JNews - Pay Writer plugin endpoints
Web server access logs showing requests with file path references to sensitive files like wp-config.php, /etc/passwd, or log files
Unexpected file access patterns in system audit logs indicating reads of configuration or sensitive files
Error messages in WordPress debug logs indicating failed file inclusion attempts

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block requests containing path traversal sequences targeting WordPress plugin directories
Monitor web server logs for requests to /wp-content/plugins/jnews-pay-writer/ containing suspicious path parameters
Deploy file integrity monitoring on critical WordPress files to detect unauthorized access or modifications
Enable and review WordPress debug logging for PHP inclusion errors or warnings

Monitoring Recommendations

Configure real-time alerting for HTTP requests containing encoded or unencoded directory traversal patterns
Establish baseline access patterns for plugin files and alert on anomalous access attempts
Monitor for unexpected PHP process file access to sensitive configuration files
Review web application logs regularly for patterns indicative of LFI exploitation attempts

How to Mitigate CVE-2025-68905

Immediate Actions Required

Update the JNews - Pay Writer plugin to a patched version when available from the vendor
If no patch is available, consider temporarily disabling the jnews-pay-writer plugin until a fix is released
Implement WAF rules to block path traversal attempts targeting the vulnerable plugin
Review server logs for evidence of exploitation attempts
Restrict file system permissions to limit the impact of potential LFI attacks

Patch Information

Organizations should monitor the official JNews marketplace and the Patchstack Vulnerability Report for patch availability. When a patched version becomes available, update immediately through the WordPress admin panel or by manually replacing plugin files.

Verify the plugin version after updating by checking wp-content/plugins/jnews-pay-writer/ for version information in the main plugin file header.

Workarounds

Temporarily deactivate and remove the JNews - Pay Writer plugin if it is not critical to site functionality
Implement server-side restrictions using open_basedir PHP directive to limit file access to the WordPress directory
Configure ModSecurity or similar WAF with rules to block LFI attempts targeting WordPress plugins
Use file permission hardening to ensure sensitive files like wp-config.php have restrictive permissions (e.g., 400 or 440)
Consider implementing a virtual patching solution through a WordPress security plugin until an official fix is available

bash

# Example: Restrict PHP open_basedir to WordPress directory
# Add to php.ini or .htaccess
php_admin_value open_basedir /var/www/html/wordpress/:/tmp/

# Example: Harden wp-config.php permissions
chmod 400 /var/www/html/wordpress/wp-config.php

# Example: ModSecurity rule to block path traversal
SecRule REQUEST_URI "@contains ../" "id:1001,phase:1,deny,status:403,msg:'Path traversal attempt blocked'"
