CVE-2025-15392 identifies a SQL injection vulnerability in Kohana KodiCMS up to version 13.82.135, specifically within the Search API Endpoint component. The vulnerability resides in the 'like' function located in cms/modules/pages/classes/kodicms/model/page.php. This function improperly handles the 'keyword' parameter, allowing an attacker to inject malicious SQL code. Because the endpoint is accessible remotely and does not require authentication or user interaction, an attacker can exploit this flaw to execute arbitrary SQL queries against the backend database. This can lead to unauthorized data access, data modification, or potentially full database compromise. The vulnerability has a CVSS 4.0 score of 5.3, indicating a medium severity level due to its remote exploitability and moderate impact on confidentiality, integrity, and availability. The vendor was contacted but has not issued a patch or mitigation guidance, and public exploit code is available, increasing the risk of exploitation. The lack of vendor response and patch availability means organizations must rely on internal mitigations or temporary workarounds. The vulnerability affects a widely used CMS component, which may be embedded in various websites and applications, increasing the attack surface. Given the public availability of exploits, threat actors could automate attacks against vulnerable installations, leading to data breaches or service disruptions.

For European organizations using Kohana KodiCMS version 13.82.135, this vulnerability poses a significant risk to the confidentiality and integrity of their data. Exploitation could allow attackers to extract sensitive information such as user credentials, business data, or intellectual property. Additionally, attackers could modify or delete data, impacting the availability and trustworthiness of affected systems. Public exploit availability increases the likelihood of automated attacks, potentially leading to widespread compromise. Organizations in sectors with high regulatory requirements, such as finance, healthcare, and government, face additional compliance risks if data breaches occur. The absence of a vendor patch means prolonged exposure, increasing the window for attackers. Furthermore, compromised websites could be used to distribute malware or conduct phishing campaigns, amplifying the threat. The impact extends beyond individual organizations to their customers and partners, potentially damaging reputation and incurring financial losses.

Given the lack of an official patch, European organizations should implement immediate mitigations. First, conduct a thorough code review of the vulnerable 'like' function and implement strict input validation and sanitization on the 'keyword' parameter to prevent SQL injection. Employ parameterized queries or prepared statements if possible. Restrict access to the Search API Endpoint by implementing network-level controls such as IP whitelisting or web application firewalls (WAFs) configured to detect and block SQL injection patterns. Monitor logs for suspicious activity targeting the vulnerable endpoint. If feasible, temporarily disable or isolate the Search API Endpoint until a secure patch is available. Regularly back up databases and verify backup integrity to enable recovery in case of compromise. Educate development and security teams about this vulnerability and ensure rapid response capabilities. Engage with the vendor or community for updates and consider migrating to alternative CMS platforms if the vendor remains unresponsive. Finally, apply broader security best practices such as least privilege for database accounts and segmentation to limit potential damage.
