MITRE ATT&CK
1 technique across 1 tactic: Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires a local, low-privileged user account (PR:L) on the target Windows system - remote, unauthenticated access is not sufficient given AV:L. ESET AV Remover (standalone) must be installed and its privileged RPC-exposed component must be actively running, which typically occurs only during an AV removal/migration workflow rather than as a persistent background service. No user interaction or special timing is required once the service is active. Exploitation is limited to the window in which AV Remover is running; standard user accounts without local interactive or RDP access cannot reach the local RPC endpoint. |
| Impact | 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. Real-world risk is bounded by the local attack vector: an attacker must already have interactive or remote shell access with a standard-user account before exploitation is possible, which limits the exposure surface compared to network-exploitable vulnerabilities. Attack complexity is genuinely low once local access is established - no race condition or special timing is required (AT:N). Privilege impact is total (VC/VI/VA all High), consistent with a SYSTEM-level escalation on Windows. No EPSS score is available from the provided data, and the absence of a KEV listing and public POC suggests this has not been observed in active exploitation campaigns. That said, even a mid-sized IT department in swidnica conducting an AV migration project would expose endpoints to this risk whenever AV Remover is executed - the tool's transient usage model means the attack window is narrow but real during migration windows. The primary risk is insider threat or post-initial-access lateral movement, not opportunistic internet-facing exploitation. |
| Exploit ScenarioDerived | An attacker who has compromised a standard user account on a Windows endpoint - via phishing or credential theft - waits for or triggers an AV migration workflow where ESET AV Remover is executed. The attacker sends a specially crafted RPC message to the tool's privileged service component; because the RPC handler does not properly validate caller privileges, the malicious call executes with SYSTEM rights. No public POC is known at time of analysis, but the low attack complexity (AC:L) suggests exploitation would not require advanced tooling once the mechanism is understood. |

Alert meAnalysisAIv1 – Sep 09, 2026
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. No active exploitation has been confirmed (not in CISA KEV), and no public exploit code has been identified at time of analysis.
RemediationAI
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. Because AV Remover is a transient utility rather than a persistently installed service, organizations should ensure that only the updated version is distributed to endpoints during AV migration workflows. As a compensating control prior to patching, restrict execution of the AV Remover binary to privileged administrator accounts only (e.g., via AppLocker or Windows Defender Application Control policy targeting the binary path), eliminating the low-privileged local user attack surface. Avoid running the tool in shared or multi-user session environments until the patch is applied.

Technical ContextAI · show details
ESET AV Remover is a standalone Windows utility produced by ESET spol. s r.o. designed to cleanly remove third-party antivirus products prior to installing ESET software. To remove deeply integrated AV components, the tool runs a privileged helper process or service - likely as SYSTEM - that exposes an RPC (Remote Procedure Call) interface for inter-process communication. CWE-269 (Improper Privilege Management) identifies the root cause: the RPC endpoint does not adequately verify the privilege level of calling processes before dispatching privileged operations, allowing a low-privilege local account to invoke elevated functionality. The affected CPE (cpe:2.3:a:eset_spol._s.r.o.:eset_av_remover_(standalone):*:*:*:*:*:*:*:*) uses a wildcard version field, indicating the flaw spans a broad or unspecified version range rather than a single release.

DescriptionCVE.org
Improper Privilege Management vulnerability in ESET AV Remover (standalone) allows Privilege Escalation via especially crafted RPC.
Executive ViewAI
ESET AV Remover contains a local privilege escalation vulnerability (CVSS 8.5) allowing low-privileged users to gain full system control through improper RPC access controls. This affects IT staff and system administrators using the tool for malware remediation, creating a risk that endpoint cleanup operations could become a vector for attackers with existing local access to escalate to full system compromise.
No vendor-released patch identified at time of analysis. Interim mitigations: (1) restrict ESET AV Remover execution permissions to administrative accounts via OS access controls; (2) execute the tool only on isolated systems or jump hosts with minimal data sensitivity; (3) disable the service/tool entirely if operationally redundant; (4) implement file-system and registry-level monitoring on RPC-related system components for anomalous calls; (5) require change-control approval and formal handoff procedures before running the tool in any production environment.
