CVE-2025-62992: Everest Backup CSRF Vulnerability

CVE-2025-62992 Overview

CVE-2025-62992 is a Cross-Site Request Forgery (CSRF) vulnerability combined with Path Traversal affecting the Everest Backup plugin for WordPress developed by everestthemes. This vulnerability allows attackers to exploit insufficient CSRF protections to perform unauthorized path traversal operations, potentially leading to access or manipulation of sensitive files outside the intended directory structure.

Critical Impact

Attackers can leverage CSRF to trick authenticated administrators into executing malicious requests that traverse file paths, potentially exposing sensitive configuration files, backup data, or enabling further exploitation of the WordPress installation.

Affected Products

• everestthemes Everest Backup plugin versions through 2.3.11
• WordPress installations using the vulnerable Everest Backup plugin
• Any WordPress site with unauthenticated or authenticated users interacting with malicious content

Technical Details for CVE-2025-62992

Vulnerability Analysis

This vulnerability combines two distinct attack vectors: Cross-Site Request Forgery (CSRF) and Path Traversal. The Everest Backup plugin fails to implement adequate CSRF token validation on critical administrative functions that handle file operations. When an authenticated administrator visits a malicious page controlled by an attacker, the attacker can trigger unauthorized requests to the backup plugin's endpoints.

The path traversal component allows attackers to manipulate file path parameters within these forged requests, using sequences like ../ to escape the intended directory boundaries. This combination is particularly dangerous because it allows remote attackers to access or manipulate files anywhere on the filesystem that the web server has permissions to read or write.

The attack requires user interaction—specifically, an authenticated WordPress administrator must be tricked into visiting a malicious website or clicking a crafted link while logged into their WordPress dashboard. However, the lack of authentication requirements for the initial attack vector and no user interaction beyond that initial click means exploitation can occur with relatively low complexity.

Root Cause

The root cause of CVE-2025-62992 lies in insufficient security controls within the Everest Backup plugin:

1. Missing CSRF Token Validation: Administrative functions that handle file operations do not properly verify CSRF tokens (nonces in WordPress terminology), allowing cross-origin requests to be processed as legitimate.

2. Inadequate Path Sanitization: File path parameters passed to backup-related functions are not properly sanitized to prevent directory traversal sequences. The plugin fails to validate that requested paths remain within the intended backup directory.

3. Improper Input Validation: User-supplied input containing path components is processed without adequate filtering of malicious characters and sequences like ../, ..\\, or URL-encoded variants.

Attack Vector

The attack exploits network-accessible WordPress administrative endpoints through the following mechanism:

An attacker crafts a malicious web page containing hidden forms or JavaScript that targets the vulnerable Everest Backup plugin endpoints. When an authenticated WordPress administrator visits this malicious page, their browser automatically sends the forged request to their WordPress installation, including their authenticated session cookies.

The forged request contains manipulated file path parameters with directory traversal sequences. Since the plugin lacks proper CSRF validation, it processes the request as if it came from a legitimate administrative action. The path traversal payload then allows the attacker to access files outside the intended backup directory, potentially reading sensitive configuration files like wp-config.php or writing malicious content to accessible locations.

The attack requires no privileges on the target system but does require a privileged user to trigger the malicious request through social engineering.

Detection Methods for CVE-2025-62992

Indicators of Compromise

• Unusual HTTP requests to Everest Backup plugin endpoints containing path traversal sequences (../, ..%2f, ..\\)
• Access logs showing requests to backup plugin endpoints originating from external referrers
• Unexpected file access patterns in WordPress directories, particularly reads of wp-config.php or other sensitive files
• Backup operations or file accesses occurring without corresponding legitimate administrative activity

Detection Strategies

• Monitor web server access logs for requests containing directory traversal patterns targeting /wp-content/plugins/everest-backup/ endpoints
• Implement Web Application Firewall (WAF) rules to detect and block CSRF attacks and path traversal attempts
• Review WordPress audit logs for backup operations that correlate with visits to external websites
• Deploy SentinelOne Singularity platform for real-time detection of file system anomalies and suspicious plugin behavior

Monitoring Recommendations

• Enable detailed access logging on WordPress installations and monitor for anomalous request patterns
• Configure alerts for any file access attempts outside the designated backup directory
• Implement integrity monitoring on critical WordPress files such as wp-config.php and core plugin files
• Use SentinelOne's behavioral AI to detect exploitation attempts and unauthorized file operations in real-time

How to Mitigate CVE-2025-62992

Immediate Actions Required

• Update the Everest Backup plugin to a patched version beyond 2.3.11 immediately
• Audit WordPress installations for any signs of compromise or unauthorized file access
• Review backup files and restore points for any evidence of tampering
• Implement additional WAF rules to block CSRF and path traversal attack patterns
• Consider temporarily disabling the Everest Backup plugin until a patch is applied

Patch Information

Organizations using the Everest Backup plugin should update to the latest available version that addresses CVE-2025-62992. Check the Patchstack Everest Backup Vulnerability advisory for the most current patch information and remediation guidance.

Ensure all WordPress plugins are kept up-to-date and subscribe to security notifications from plugin vendors and security research organizations like Patchstack.

Workarounds

• Restrict access to WordPress administrative functions using IP allowlisting where feasible
• Implement additional CSRF protection at the web server or WAF level
• Educate administrators about the risks of clicking unknown links while authenticated to WordPress
• Consider using a security plugin that adds additional nonce verification to plugin operations
• Deploy SentinelOne endpoint protection to detect and prevent exploitation attempts at the host level

# WordPress configuration hardening example
# Add to wp-config.php to restrict file editing capabilities
define('DISALLOW_FILE_EDIT', true);
define('DISALLOW_FILE_MODS', true);

# Consider restricting plugin execution with .htaccess rules
# Add to /wp-content/plugins/everest-backup/.htaccess
# Deny access to sensitive files until patched
