CVE-2025-57529 identifies a critical SQL Injection vulnerability in the YouDataSum CPAS Audit Management System versions up to 4.9. The flaw exists in the /cpasList/findArchiveReportByDah endpoint, where insufficient input validation allows an attacker to inject arbitrary SQL commands through a crafted parameter. This vulnerability does not require authentication, enabling remote attackers to exploit it without prior access. Successful exploitation can lead to unauthorized data retrieval, modification, or deletion within the backend database, potentially exposing sensitive audit and compliance data. The vulnerability stems from the failure to properly sanitize or parameterize user inputs before incorporating them into SQL queries. No CVSS score has been assigned yet, and no patches or official fixes have been published. Although no known exploits are currently in the wild, the nature of SQL Injection vulnerabilities makes this a high-risk issue. Attackers could leverage this flaw to bypass access controls, extract confidential information, or disrupt audit processes. The affected product is primarily used for audit management, making the confidentiality and integrity of stored data critical. The vulnerability's remote and unauthenticated exploitation vector increases its threat level, especially in environments where the system is exposed to untrusted networks.

For European organizations, exploitation of this vulnerability could result in unauthorized disclosure of sensitive audit data, potentially including personal data protected under GDPR. This could lead to regulatory penalties, reputational damage, and loss of stakeholder trust. The integrity of audit records could be compromised, undermining compliance and governance efforts. Availability impacts could also arise if attackers manipulate or delete database records, disrupting audit operations. Organizations in sectors with stringent compliance requirements, such as finance, healthcare, and government, face heightened risks. The lack of authentication for exploitation broadens the attack surface, especially for systems accessible over the internet or less-secured internal networks. Given the critical role of audit management systems in ensuring organizational accountability, this vulnerability could facilitate further attacks or insider threats if leveraged as an initial foothold.

Immediate mitigation should focus on implementing robust input validation and sanitization for all parameters accepted by the /cpasList/findArchiveReportByDah endpoint. Developers should refactor the code to use parameterized queries or prepared statements to prevent SQL Injection. Until a patch is available, organizations should restrict network access to the affected system, limiting it to trusted internal networks and applying strict firewall rules. Employ Web Application Firewalls (WAFs) with SQL Injection detection capabilities to monitor and block malicious requests targeting this endpoint. Conduct thorough code reviews and penetration testing to identify and remediate similar injection points. Monitor database logs and application logs for unusual query patterns or errors indicative of exploitation attempts. Additionally, organizations should prepare incident response plans to quickly address potential breaches involving this system. Regular backups of audit data should be maintained to enable recovery in case of data tampering or loss.
