Local attack vector (AV:L) and low privilege (PR:L) reflect the RPC-on-local-machine exploitation; no scope change as the escalation stays within the same host; full C/I/A:H because SYSTEM-level access grants complete control.

Improper Privilege Management vulnerability in ESET AV Remover (standalone) allows Privilege Escalation via especially crafted RPC.
AnalysisAI
Local privilege escalation in ESET AV Remover (standalone) enables a low-privileged local user to attain SYSTEM-level control by sending specially crafted RPC messages to the tool's privileged service component. The root cause is CWE-269 (Improper Privilege Management): the RPC handler fails to enforce access controls commensurate with the operations it exposes, allowing an unprivileged caller to invoke functionality that executes at a higher privilege level. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a local, low-privileged user account (PR:L) on the target Windows system - remote, unauthenticated access is not sufficient given AV:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H) rates this 8.5, reflecting high but locally constrained impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the fixed version of ESET AV Remover as detailed in ESET Customer Advisory CA9000 at https://support.eset.com/en/ca9000-eset-customer-advisory-local-privilege-escalation-vulnerability-in-eset-av-remover-fixed. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all systems with ESET AV Remover installed and restrict tool execution to administrative-level accounts only via Group Policy or equivalent access controls; audit execution logs for recent suspicious RPC activity. …
