6.0 MEDIUM

Local access with pre-existing administrator rights drives AV:L and PR:H; low complexity, and the flaw both discloses sensitive data (C:H) and enables host DoS (A:H) with no integrity impact.

DescriptionCVE.org

Allocation of Resources Without Limits and Throttling and Sensitive Information in Resource Not Removed Before Reuse in the ASUS System Control Interface driver and ASUS Business Manager allow a local administrator to disclose sensitive information via crafted IOCTL requests, which, in severe cases, may lead to a Denial of Service (DoS) on the system. Refer to the ' Security Update for ASUS System Control Interface  ' section on the ASUS Security Advisory for more information.

AnalysisAI

Local information disclosure and denial of service in the ASUS System Control Interface driver (v3 and earlier) and ASUS Business Manager lets a user already holding local administrator rights issue crafted IOCTL requests to read leftover sensitive data from kernel/driver buffers and, in severe cases, exhaust unthrottled resources to crash the host. The flaw stems from missing resource limits (CWE-770) combined with reuse of memory that still contains prior sensitive contents. …

Vulnerability AssessmentAI

Exploitation Exploitation requires local administrator privileges on the target ASUS system (CVSS PR:H) and local access (AV:L) - it cannot be performed remotely or by a standard/unprivileged user. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The vendor CVSS 4.0 base score is 8.2 (High) with vector AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:H/SI:N/SA:H, meaning local access, low complexity, but high privileges (administrator) already required - a significant limiting factor. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has already obtained local administrator privileges on an ASUS business notebook - for example after an earlier phishing-plus-privilege-escalation foothold - sends crafted IOCTL requests to the System Control Interface driver to read back stale buffer contents containing sensitive data, then repeats malformed requests to exhaust driver resources and crash the machine. No public POC is known, and low attack complexity means a knowledgeable admin-level attacker could develop one against the driver's IOCTL interface.
Remediation Patch available per vendor advisory: update the ASUS System Control Interface / System Control Interface v3 driver and ASUS Business Manager to the fixed builds described in the 'Security Update for ASUS System Control Interface' section of the ASUS Security Advisory at https://www.asus.com/security-advisory/ (exact fixed version not provided in this dataset - obtain it from that advisory). … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify and inventory all systems running ASUS System Control Interface driver v3 and earlier, plus any ASUS Business Manager installations, documenting affected versions and the count of users with local administrator rights. …
