CVE-2024-26162 is a high-severity vulnerability identified in Microsoft Windows 10 Version 1809, specifically affecting the ODBC Driver component. The root cause is an incorrect conversion between numeric types (CWE-681), which can lead to memory corruption or unexpected behavior during data processing. This vulnerability allows an unauthenticated attacker to remotely execute arbitrary code on the affected system by exploiting the ODBC driver, which is used for database connectivity. The CVSS 3.1 base score of 8.8 reflects the critical nature of this flaw, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The impact scope is unchanged (S:U), and the vulnerability affects confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits are currently in the wild, the vulnerability's characteristics make it a significant risk, especially for systems still running Windows 10 Version 1809 (build 10.0.17763.0), which is an older release and may not be fully supported or patched in all environments. The vulnerability could be triggered when a user interacts with a maliciously crafted data source or application that leverages the vulnerable ODBC driver, potentially leading to full system compromise.

For European organizations, the impact of CVE-2024-26162 can be substantial. Many enterprises and public sector entities still operate legacy Windows 10 Version 1809 systems due to application compatibility or slow upgrade cycles. Exploitation could lead to remote code execution, enabling attackers to gain control over critical systems, exfiltrate sensitive data, disrupt operations, or deploy ransomware. The vulnerability affects confidentiality, integrity, and availability, posing risks to data protection compliance under GDPR and other regulations. Organizations relying on ODBC for database connectivity in financial services, healthcare, manufacturing, and government sectors are particularly at risk. The requirement for user interaction means phishing or social engineering campaigns could be used to trigger the exploit, increasing the attack surface. The absence of known exploits in the wild currently provides a window for proactive mitigation, but the high severity score demands urgent attention to prevent potential targeted attacks.

European organizations should prioritize upgrading or patching systems running Windows 10 Version 1809 to the latest supported Windows 10 or Windows 11 versions where this vulnerability is resolved. If immediate upgrade is not feasible, organizations should implement network-level controls to restrict access to systems with the vulnerable ODBC driver, especially from untrusted networks. Employ application whitelisting and endpoint detection and response (EDR) solutions to monitor and block suspicious activities related to ODBC usage. User awareness training should emphasize the risks of interacting with unknown or suspicious data sources and attachments. Additionally, organizations should audit their inventory to identify all systems running the affected build and apply any available Microsoft security updates or workarounds as soon as they are released. Monitoring for unusual network traffic or process behavior related to database connectivity can help detect exploitation attempts early.
