CVE-2025-22371 is a SQL Injection vulnerability identified in the SicommNet BASEC SaaS service, specifically affecting the login page. The vulnerability arises from improper neutralization of special elements used in SQL commands (CWE-89), allowing an unauthenticated remote attacker to inject arbitrary SQL code. This flaw enables bypassing authentication mechanisms and executing arbitrary SQL commands against the backend database. The affected versions include BASEC deployments from at least December 14, 2021, and potentially earlier, indicating the vulnerability may have been present for an extended period before its public disclosure and patching on April 16, 2025. The vulnerability does not require any authentication or user interaction, increasing its risk profile. Although no known exploits are currently reported in the wild, the nature of SQL Injection vulnerabilities makes them highly attractive targets for attackers seeking unauthorized access, data exfiltration, or disruption of service. The vulnerability impacts the confidentiality, integrity, and availability of the affected systems, as attackers can manipulate database queries to extract sensitive information, modify data, or cause denial of service. SicommNet BASEC is a SaaS platform, implying that multiple organizations relying on this service could be affected simultaneously if they have not applied the patch. The lack of a CVSS score necessitates an independent severity assessment based on the technical details and potential impact.

For European organizations using SicommNet BASEC, this vulnerability poses significant risks. Successful exploitation could lead to unauthorized access to sensitive corporate or customer data, undermining confidentiality and potentially violating GDPR and other data protection regulations. Integrity of stored data could be compromised, leading to corrupted records or fraudulent transactions. Availability may also be affected if attackers execute commands that disrupt database operations or cause service outages. Given the SaaS nature of BASEC, multiple clients could be impacted by a single exploit, amplifying the potential damage. Organizations in sectors such as finance, healthcare, and critical infrastructure that rely on BASEC for authentication or data management are particularly at risk. The breach of authentication mechanisms could facilitate lateral movement within networks or escalate privileges, increasing the scope of compromise. Additionally, reputational damage and regulatory penalties could result from data breaches stemming from this vulnerability.

Organizations should immediately verify whether they use SicommNet BASEC versions from December 14, 2021, onwards and ensure that the patch released on April 16, 2025, is applied without delay. If patching is not immediately feasible, implementing Web Application Firewalls (WAFs) with specific rules to detect and block SQL injection attempts targeting the login page can provide temporary protection. Conduct thorough input validation and parameterized query enforcement on all database interactions to prevent injection vectors. Regularly audit and monitor database logs for unusual query patterns indicative of injection attempts. Employ multi-factor authentication (MFA) to reduce the impact of potential authentication bypass. Additionally, organizations should review and limit database user privileges to the minimum necessary to reduce the potential impact of successful injection attacks. Incident response plans should be updated to include detection and containment procedures for SQL injection attacks. Finally, coordinate with SicommNet for any additional security advisories or updates related to BASEC.
