CVE-2025-13077 is a time-based blind SQL Injection vulnerability identified in the payamito sms woocommerce plugin for WordPress, specifically in versions up to and including 1.3.5. The vulnerability arises from improper neutralization of special elements in SQL commands (CWE-89), particularly due to insufficient escaping and lack of prepared statements for the 'columns' parameter. This flaw allows unauthenticated attackers to inject arbitrary SQL code into existing queries, enabling them to extract sensitive data from the backend database by leveraging time delays to infer information. The attack vector requires no authentication or user interaction, increasing the risk of automated exploitation. The vulnerability has a CVSS 3.1 base score of 7.5, reflecting its high severity with network attack vector, low attack complexity, no privileges required, and no user interaction needed. Although no public exploits are currently known, the plugin’s widespread use in Persian-language WooCommerce stores makes it a significant threat. The lack of patches or updates at the time of disclosure necessitates immediate mitigation efforts by administrators. This vulnerability highlights the critical need for secure coding practices such as parameterized queries and rigorous input validation in WordPress plugin development.

The primary impact of CVE-2025-13077 is the potential unauthorized disclosure of sensitive information stored in the WordPress site's database, including customer data, credentials, and transactional records. Since the vulnerability allows unauthenticated remote attackers to perform time-based blind SQL injection, attackers can systematically extract data without triggering immediate errors, making detection difficult. This can lead to data breaches, loss of customer trust, and regulatory compliance violations. Additionally, attackers could leverage the extracted data for further attacks such as credential stuffing or phishing campaigns. The vulnerability does not directly affect data integrity or availability but compromises confidentiality significantly. Organizations relying on the payamito sms woocommerce plugin for critical e-commerce or communication functions face reputational damage and potential financial losses if exploited. The ease of exploitation and network accessibility increase the likelihood of targeted attacks, especially in regions where this plugin is prevalent.

To mitigate CVE-2025-13077, organizations should immediately update the payamito sms woocommerce plugin to a patched version once available. Until a patch is released, administrators should implement strict input validation and sanitization on the 'columns' parameter, ensuring that only expected values are accepted. Employing web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting this parameter can reduce risk. Disabling or restricting access to the vulnerable plugin functionality for unauthenticated users can also help. Regularly monitoring logs for unusual query patterns or time delays indicative of blind SQL injection attempts is recommended. Additionally, database permissions should be minimized to limit the impact of any successful injection. Organizations should also consider conducting security audits of all WordPress plugins to identify and remediate similar injection vulnerabilities proactively. Finally, educating developers on secure coding practices, including the use of prepared statements and parameterized queries, is essential to prevent future occurrences.
