CVE-2025-15088 is an SQL injection vulnerability identified in the ketr JEPaaS platform, affecting all versions up to 7.2.8. The vulnerability resides in the postilService.loadPostils function within the /je/postil/postil/loadPostil file, where the keyWord parameter is improperly sanitized, allowing attackers to inject malicious SQL code. This injection flaw enables remote attackers to manipulate backend database queries without requiring user interaction, though low-level privileges are necessary to exploit it. The vulnerability can lead to unauthorized data access, modification, or deletion, impacting the confidentiality, integrity, and availability of the system. The CVSS 4.0 score is 5.3 (medium), reflecting the moderate impact and ease of exploitation. Despite the vendor being notified early, no patches or official responses have been provided, and a public exploit is available, increasing the risk of exploitation. The vulnerability does not require user interaction but does require some privileges, limiting the attack surface somewhat. The lack of vendor response and patch availability means organizations must rely on compensating controls until an official fix is released.

For European organizations, this vulnerability poses a moderate risk, particularly for those using ketr JEPaaS in critical business processes or handling sensitive data. Successful exploitation could lead to unauthorized access to confidential information, data corruption, or service disruption. This could result in regulatory non-compliance issues under GDPR if personal data is exposed. The availability of a public exploit increases the likelihood of attacks, especially from opportunistic threat actors. Organizations in sectors such as finance, healthcare, and government that rely on JEPaaS for workflow or data management are at heightened risk. The absence of vendor patches means that the vulnerability could persist in production environments, potentially leading to data breaches or operational interruptions. Additionally, the medium severity rating suggests that while the impact is not catastrophic, it is significant enough to warrant immediate attention and mitigation.

1. Implement strict input validation and sanitization on the keyWord parameter to prevent SQL injection attempts. 2. Deploy Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection payloads targeting the vulnerable endpoint. 3. Restrict access to the postilService.loadPostils function to trusted users and networks, minimizing exposure. 4. Monitor logs and network traffic for unusual database query patterns or repeated failed attempts indicative of exploitation attempts. 5. Conduct regular security assessments and penetration tests focusing on injection vulnerabilities in JEPaaS deployments. 6. If possible, isolate the affected service in a segmented network zone to limit potential lateral movement. 7. Engage with the vendor or community to track patch releases and apply updates promptly once available. 8. Consider temporary disabling or restricting the vulnerable functionality if it is not critical to operations until a patch is released.
