Technical Analysis

CVE-2025-40671 is a critical SQL injection vulnerability identified in AES Multimedia's Gestnet version 1.07. The vulnerability arises from improper neutralization of CRLF sequences (CWE-93) in the 'fk_remoto_central' parameter of the '/webservices/articles.php' endpoint. This flaw allows an unauthenticated attacker to perform unauthorized SQL commands, enabling retrieval, creation, modification, and deletion of database records. The vulnerability is remotely exploitable over the network without requiring any privileges or user interaction, as indicated by the CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N). The impact on confidentiality, integrity, and availability is high, as attackers can fully manipulate backend databases, potentially leading to data breaches, data loss, or service disruption. The vulnerability does not require authentication or user interaction, increasing the risk of automated exploitation. Although no known exploits are currently reported in the wild, the critical CVSS score of 9.3 underscores the urgency for remediation. The root cause is improper handling of CRLF sequences, which facilitates injection of malicious SQL payloads through the vulnerable parameter. The absence of available patches at the time of publication further elevates the risk for organizations using this product version.

Potential Impact

For European organizations using AES Multimedia's Gestnet v1.07, this vulnerability poses a severe risk to the confidentiality, integrity, and availability of their data. Given Gestnet's role in managing multimedia content and potentially sensitive business data, exploitation could lead to unauthorized data disclosure, data tampering, or complete database compromise. This could result in operational disruptions, regulatory non-compliance (notably GDPR violations due to data breaches), financial losses, and reputational damage. The ability to execute arbitrary SQL commands without authentication means attackers can pivot within the network, escalate privileges, or deploy ransomware. Critical infrastructure or sectors relying on Gestnet for content management or data services are particularly vulnerable. The lack of known exploits currently may provide a window for mitigation, but the ease of exploitation and high impact necessitate immediate action to prevent potential attacks.

Mitigation Recommendations

European organizations should immediately conduct an inventory to identify deployments of AES Multimedia Gestnet version 1.07. Until a vendor patch is released, implement the following mitigations: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'fk_remoto_central' parameter and the '/webservices/articles.php' endpoint. 2) Restrict network access to the Gestnet web services to trusted IP addresses and internal networks only, minimizing exposure to external attackers. 3) Monitor logs for anomalous SQL queries or unusual activity patterns indicative of exploitation attempts. 4) Engage with AES Multimedia for timely patch releases and apply updates as soon as they become available. 5) Conduct code reviews or penetration testing to identify and remediate similar injection flaws in other parameters or endpoints. 6) Implement database-level protections such as least privilege access, query parameterization, and input validation to reduce the impact of injection attacks. 7) Prepare incident response plans specific to SQL injection attacks to enable rapid containment and recovery.
