CVE-2024-30025: CWE-125: Out-of-bounds Read in Microsoft Windows 10 Version 1809
Windows Common Log File System Driver Elevation of Privilege Vulnerability
AI Analysis
Technical Summary
CVE-2024-30025 is a high-severity elevation of privilege vulnerability affecting the Windows Common Log File System (CLFS) driver in Microsoft Windows 10 Version 1809 (build 10.0.17763.0). The underlying issue is an out-of-bounds read (CWE-125), where the CLFS driver improperly handles memory bounds, allowing a local attacker with limited privileges (low-level privileges) to read memory outside the intended buffer boundaries. This vulnerability does not require user interaction but does require local access with some privileges (PR:L). Exploiting this flaw can lead to a complete compromise of confidentiality, integrity, and availability of the affected system because the attacker can potentially read sensitive kernel memory, escalate privileges to SYSTEM level, and execute arbitrary code or cause system instability. The CVSS v3.1 base score is 7.8, reflecting the high impact on confidentiality, integrity, and availability, combined with relatively low attack complexity and privileges required. Although no known exploits are currently reported in the wild, the vulnerability is publicly disclosed and patched status is not explicitly provided in the data. The vulnerability is specific to Windows 10 Version 1809, which is an older but still in-use version of Windows 10, often found in enterprise environments that have not upgraded to newer versions. The lack of patch links suggests organizations must verify patch availability and apply updates promptly. The vulnerability's exploitation vector is local, meaning attackers must have some foothold on the system, but once exploited, it can lead to full system compromise.
Potential Impact
For European organizations, this vulnerability poses a significant risk, especially in sectors where Windows 10 Version 1809 remains in use due to legacy application dependencies or slow upgrade cycles, such as government, manufacturing, and critical infrastructure. Successful exploitation could allow attackers to escalate privileges from a low-privileged user to SYSTEM, enabling them to bypass security controls, access sensitive data, install persistent malware, or disrupt operations. This could lead to data breaches involving personal data protected under GDPR, operational downtime, and reputational damage. The high impact on confidentiality, integrity, and availability means that critical systems could be fully compromised. Since the attack requires local access, it is particularly concerning in environments where endpoint security is weak or where attackers can gain initial access through phishing, physical access, or insider threats. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate it, as proof-of-concept exploits could emerge rapidly after public disclosure.
Mitigation Recommendations
European organizations should prioritize the following specific mitigation steps: 1) Conduct an inventory to identify all systems running Windows 10 Version 1809 and assess their criticality. 2) Verify with Microsoft or trusted security advisories the availability of patches or security updates addressing CVE-2024-30025 and apply them immediately. 3) If patches are not yet available, consider temporary mitigations such as restricting local user privileges, enforcing strict application whitelisting, and enhancing endpoint detection and response (EDR) capabilities to detect suspicious local privilege escalation attempts. 4) Implement network segmentation and least privilege principles to limit the ability of attackers to gain local access on critical systems. 5) Increase monitoring for unusual activity indicative of privilege escalation attempts, including anomalous access to system logs or kernel memory. 6) Educate users and administrators about the risks of local privilege escalation vulnerabilities and enforce strong authentication and physical security controls to reduce the risk of initial local compromise. 7) Plan and execute an upgrade strategy to move affected systems to supported and fully patched Windows versions to reduce exposure to legacy vulnerabilities.
