CVE-2025-6437 is a high-severity SQL Injection vulnerability identified in the Ads Pro Plugin - Multi-Purpose WordPress Advertising Manager developed by scripteo. This plugin is widely used to manage advertising on WordPress sites. The vulnerability exists in all versions up to and including 4.89. The root cause is improper neutralization of special elements in SQL commands, specifically via the 'oid' parameter. This parameter is insufficiently escaped and the SQL queries are not properly prepared, allowing an unauthenticated attacker to inject arbitrary SQL code. Exploitation does not require authentication or user interaction, and the attacker can append additional SQL queries to the existing ones. This can lead to unauthorized extraction of sensitive information from the backend database, compromising confidentiality. The CVSS v3.1 base score is 7.5, reflecting a high severity with network attack vector, low attack complexity, no privileges required, and no user interaction needed. The vulnerability affects the confidentiality of data but does not impact integrity or availability directly. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is classified under CWE-89, which covers improper neutralization of special elements used in SQL commands, a common and critical web application security flaw. Given the widespread use of WordPress and the popularity of advertising plugins, this vulnerability poses a significant risk to websites using this plugin, especially those handling sensitive user or business data.

For European organizations, the impact of CVE-2025-6437 can be substantial. Many European companies rely on WordPress for their web presence, including e-commerce, media, and marketing sites that may use the Ads Pro Plugin for managing advertisements. Successful exploitation could lead to unauthorized disclosure of sensitive customer data, business intelligence, or internal configuration details stored in the database. This could result in reputational damage, regulatory penalties under GDPR for data breaches, and financial losses. Since the vulnerability allows unauthenticated remote exploitation, attackers can operate at scale, targeting multiple vulnerable sites across Europe. The lack of impact on integrity and availability means attackers primarily gain read-only access to data, but this is often sufficient for data theft or reconnaissance for further attacks. The absence of known exploits currently provides a window for mitigation, but the ease of exploitation and the public disclosure of the vulnerability increase the risk of imminent attacks. Organizations with high-profile websites or those in regulated sectors such as finance, healthcare, or government are particularly at risk due to the sensitivity of their data and the potential for targeted attacks.

To mitigate CVE-2025-6437, European organizations should take immediate and specific actions beyond generic advice: 1) Identify and inventory all WordPress installations using the Ads Pro Plugin, especially versions up to 4.89. 2) Apply vendor patches as soon as they become available; if no official patch exists yet, consider temporarily disabling the plugin or removing it if feasible. 3) Implement Web Application Firewall (WAF) rules specifically targeting SQL injection attempts on the 'oid' parameter to block malicious payloads at the perimeter. 4) Conduct thorough code reviews and security testing on custom or third-party WordPress plugins to detect similar injection flaws. 5) Restrict database user permissions for WordPress to the minimum necessary, limiting the potential impact of SQL injection. 6) Monitor web server and application logs for suspicious query patterns or repeated access attempts to the vulnerable parameter. 7) Educate web administrators and developers on secure coding practices, emphasizing parameterized queries and prepared statements to prevent injection vulnerabilities. 8) Consider deploying runtime application self-protection (RASP) solutions to detect and block injection attacks in real time. These targeted measures will reduce the attack surface and help protect sensitive data from unauthorized extraction.
