CVE-2019-19548 in Power Eraser
Summary
by MITRE
Norton Power Eraser, prior to 5.3.0.67, may be susceptible to a privilege escalation vulnerability, which is a type of issue whereby an attacker may attempt to compromise the software application to gain elevated access to resources that are normally protected from an application or user.

Norton Power Eraser version 5.3.0.67 and earlier contains a privilege escalation vulnerability that represents a critical security flaw in endpoint protection software. This vulnerability allows an attacker to potentially elevate their privileges within the system, bypassing normal access controls that should prevent unauthorized elevation of permissions. The flaw exists in the application's privilege management mechanisms, creating an opportunity for malicious actors to exploit the software's intended functionality for unauthorized system access. The vulnerability affects users who have installed Norton Power Eraser prior to the 5.3.0.67 update, leaving them exposed to potential privilege escalation attacks that could compromise the entire system.
The technical implementation of this vulnerability stems from improper privilege handling within Norton Power Eraser's codebase. When the application executes certain operations, it fails to properly validate or enforce privilege boundaries, allowing a low-privilege user or process to gain elevated system permissions. This typically occurs through manipulation of system calls, file access patterns, or registry modifications that should normally be restricted to administrator-level processes. The flaw manifests when the application performs operations that require elevated privileges without adequately verifying the requesting entity's authorization level, creating a path for privilege escalation through improper access control enforcement.
The operational impact of this vulnerability is significant as it enables attackers to compromise systems that have Norton Power Eraser installed. An attacker who successfully exploits this vulnerability could gain administrative privileges on the target system, potentially leading to full system compromise, data exfiltration, or deployment of additional malware. The vulnerability is particularly concerning because Norton Power Eraser is designed to perform system-level operations and typically requires elevated privileges to function properly, making the privilege escalation path more direct and dangerous than typical applications. This vulnerability essentially allows attackers to bypass the very security controls that Norton Power Eraser is intended to provide.
This vulnerability maps to CWE-276, which describes improper privilege management in software applications, and aligns with ATT&CK technique T1068, which covers "Exploitation for Privilege Escalation." The flaw represents a classic case of insufficient access control validation where the application fails to properly enforce privilege boundaries during critical operations. Organizations should immediately update to Norton Power Eraser version 5.3.0.67 or later to remediate this issue, as the vulnerability could be exploited by attackers with minimal technical expertise. Additionally, system administrators should implement monitoring for suspicious privilege escalation activities and conduct regular security assessments to identify potential exploitation attempts. The remediation process should include comprehensive patch management procedures and verification that all affected systems have been properly updated to prevent exploitation of this critical privilege escalation vulnerability.
