CVE-2025-51667 is a high-severity SQL injection vulnerability identified in the simple-admin-core system, specifically affecting versions from v1.2.0 through v1.6.7. The vulnerability exists in the /sys-api/role/update interface, which is likely an API endpoint responsible for updating user roles or permissions within the system. SQL injection (CWE-89) vulnerabilities occur when untrusted input is improperly sanitized and directly incorporated into SQL queries, allowing an attacker to manipulate the database query execution. In this case, the limited SQL injection flaw could enable an attacker to extract sensitive data partially or disrupt normal system operations by injecting malicious SQL commands. The CVSS 3.1 base score is 7.0, indicating a high severity level. The vector string (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:L) reveals that the attack is network exploitable without requiring privileges or user interaction, but the attack complexity is high, meaning exploitation requires specific conditions or knowledge. The impact on confidentiality is high, as partial data leakage is possible, while integrity and availability impacts are low but present, due to potential disruption of system operations. No known exploits in the wild have been reported yet, and no patches are currently linked, suggesting that organizations using affected versions remain vulnerable until a fix is applied. The vulnerability's presence in a core administrative component implies that successful exploitation could undermine role management, potentially leading to privilege escalation or unauthorized access if combined with other vulnerabilities or misconfigurations.

For European organizations, the impact of CVE-2025-51667 could be significant, especially for those relying on simple-admin-core for managing administrative roles and permissions in their internal or customer-facing applications. Partial data leakage could expose sensitive personal data, intellectual property, or business-critical information, raising compliance concerns under GDPR and other data protection regulations. Disruption of normal system operations could affect business continuity, leading to downtime or degraded service quality. Given the vulnerability affects role update functionality, attackers might manipulate role assignments indirectly, potentially escalating privileges or bypassing access controls if chained with other vulnerabilities. This could lead to unauthorized access to sensitive systems or data. The high attack complexity somewhat limits immediate exploitation, but determined attackers with knowledge of the system could still leverage this flaw. The lack of available patches increases risk exposure. Organizations in sectors with stringent regulatory requirements, such as finance, healthcare, and government, may face heightened risks due to the sensitivity of data and the criticality of role management systems.

To mitigate CVE-2025-51667, European organizations should take the following specific actions: 1) Immediately audit the use of simple-admin-core versions between v1.2.0 and v1.6.7 within their environments, identifying all instances of the /sys-api/role/update interface. 2) Implement strict input validation and sanitization on all parameters accepted by the role update API, employing parameterized queries or prepared statements to prevent SQL injection. 3) Employ Web Application Firewalls (WAFs) with custom rules designed to detect and block SQL injection attempts targeting the specific API endpoint. 4) Monitor logs for unusual or suspicious activity related to role updates, including unexpected parameter values or failed SQL queries. 5) Restrict network access to the /sys-api/role/update endpoint to trusted IP addresses or internal networks where possible, reducing exposure to external attackers. 6) Engage with the simple-admin-core vendor or community to obtain patches or updates addressing this vulnerability and plan for timely deployment once available. 7) Conduct penetration testing focused on role management APIs to identify any residual injection or access control weaknesses. 8) Educate development and security teams about secure coding practices related to database interactions, emphasizing the risks of SQL injection in administrative interfaces.
