CVE-2025-15088 is a SQL injection vulnerability identified in the ketr JEPaaS platform, specifically in the postilService.loadPostils function located in /je/postil/postil/loadPostil. The vulnerability stems from insufficient input validation of the keyWord argument, which is directly incorporated into SQL queries without proper sanitization or parameterization. This flaw enables remote attackers to inject malicious SQL code, potentially allowing unauthorized data access, modification, or deletion. The vulnerability affects all versions up to 7.2.8. Exploitation requires low privileges (PR:L) but no user interaction (UI:N), and can be performed remotely (AV:N). The CVSS 4.0 score is 5.3 (medium severity), reflecting limited but meaningful impact on confidentiality, integrity, and availability with low attack complexity. The vendor has not issued patches or responded to disclosure, and a public exploit is available, increasing the risk of exploitation. While no active exploitation in the wild is reported, the presence of a public exploit necessitates urgent attention. The vulnerability does not require special privileges beyond low-level access, making it accessible to a broader attacker base. The lack of security controls such as input validation and parameterized queries is the root cause. This vulnerability could be leveraged to extract sensitive information, corrupt data, or disrupt services hosted on JEPaaS platforms.

For European organizations, exploitation of this vulnerability could lead to unauthorized access to sensitive data, including intellectual property, customer information, or internal communications managed through JEPaaS. Data integrity could be compromised by unauthorized modification or deletion of records, potentially disrupting business operations or compliance with data protection regulations such as GDPR. Availability impacts may arise if attackers execute destructive SQL commands or cause database errors, leading to service outages. Given the public availability of an exploit and lack of vendor response, organizations face increased risk of targeted attacks or opportunistic exploitation. Sectors relying heavily on JEPaaS for critical business processes, such as finance, healthcare, or government services, are particularly vulnerable. The medium severity rating indicates a moderate but actionable threat that could escalate if combined with other vulnerabilities or misconfigurations. Failure to address this vulnerability could result in regulatory penalties, reputational damage, and financial losses due to data breaches or operational disruptions.

1. Implement immediate input validation and sanitization on the keyWord parameter to prevent injection of malicious SQL code. Use parameterized queries or prepared statements wherever possible to eliminate direct concatenation of user input into SQL commands. 2. Restrict database user permissions associated with JEPaaS to the minimum necessary, avoiding elevated privileges that could amplify the impact of an injection attack. 3. Monitor application and database logs for unusual query patterns or errors indicative of SQL injection attempts. 4. Employ Web Application Firewalls (WAFs) with rules tailored to detect and block SQL injection payloads targeting the vulnerable endpoint. 5. Isolate the affected service in a segmented network zone to limit lateral movement if compromise occurs. 6. Engage with the vendor or community to obtain or develop patches or updates addressing the vulnerability. 7. Conduct thorough security assessments and penetration testing focused on injection flaws in JEPaaS deployments. 8. Educate developers and administrators on secure coding practices and the importance of input validation. 9. Prepare incident response plans specific to SQL injection attacks to enable rapid containment and remediation. 10. Consider temporary disabling or restricting access to the vulnerable function if feasible until a patch is available.
