CVE-2025-53576

ovatheme · ovatheme Ovatheme Multiple Products

A high-severity vulnerability has been identified in multiple ovatheme products, allowing an attacker to read sensitive files on the web server.

Executive summary

A high-severity vulnerability has been identified in multiple ovatheme products, allowing an attacker to read sensitive files on the web server. This flaw, known as Local File Inclusion, can be exploited remotely without authentication, potentially leading to the exposure of confidential data, system credentials, and in some cases, complete server compromise. Organizations are strongly advised to apply the vendor-supplied security patches immediately to mitigate this significant risk.

Vulnerability

This vulnerability is a Local File Inclusion (LFI) flaw. It exists because the application fails to properly sanitize user-supplied input that is used to construct a file path for a PHP include or require statement. An unauthenticated remote attacker can exploit this by crafting a malicious request containing directory traversal sequences (e.g., ../../..) to navigate the server's file system and include arbitrary files. Successful exploitation allows the attacker to view the contents of sensitive files, such as configuration files containing database credentials (wp-config.php), system user lists (/etc/passwd), or application source code.

Business impact

This is a High severity vulnerability with a CVSS score of 8.1. Exploitation could have a significant negative impact on the business. The primary risk is a data breach resulting from an attacker reading sensitive files containing customer information, intellectual property, or system credentials. If an attacker can leverage this LFI to achieve code execution (e.g., through log poisoning), they could gain full control of the affected server, leading to further network compromise, service disruption, and severe reputational damage.

Remediation

Immediate Action:

  • Apply Patches: Apply the security updates provided by ovatheme Ovatheme immediately across all affected products. Prioritize patching for internet-facing systems.
  • Monitor and Review: Actively monitor for signs of exploitation. Review web server access logs for requests containing directory traversal patterns or attempts to access common sensitive files.

Proactive Monitoring:

  • Log Analysis: Scrutinize web server logs (e.g., Apache, Nginx) for suspicious GET or POST requests. Look for patterns like ../, ..%2f, %00 (null byte), and requests for files like /etc/passwd, .env, or wp-config.php.
  • File Integrity Monitoring (FIM): Implement FIM on web servers to detect unauthorized changes to application code or critical system files, which could indicate a successful compromise.
  • WAF/IDS/IPS: Ensure that Web Application Firewall (WAF) and Intrusion Detection/Prevention System (IDS/IPS) signatures are up-to-date to detect and block LFI attack attempts.

Compensating Controls:

  • Web Application Firewall (WAF): If immediate patching is not feasible, configure a WAF with strict rules to block requests containing directory traversal sequences and other LFI payloads.
  • PHP Hardening: Ensure the PHP configuration (php.ini) is hardened by disabling allow_url_include and restricting file system access using the open_basedir directive to only the necessary directories.
  • Principle of Least Privilege: Run the web server and application processes with a dedicated, low-privilege user account to limit the scope of files an attacker can access if the vulnerability is exploited.

Exploitation status

Public Exploit Available: false

Analyst recommendation

Given the high severity (CVSS 8.1) of this vulnerability and its potential to cause a significant data breach or full system compromise, we recommend immediate action. Organizations must prioritize the deployment of the vendor-supplied security patches to all affected systems. Although this vulnerability is not currently on the CISA KEV list, its critical nature warrants treating it with the highest urgency. In parallel with patching, enhanced monitoring should be implemented to detect any potential exploitation attempts.
