CVE-2025-13703 in Advanced Security
Summary
by MITRE • 12/24/2025
VIPRE Advanced Security Incorrect Permission Assignment Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of VIPRE Advanced Security for PC. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the product installer. The issue results from incorrect permissions on a folder. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-27147.

The vulnerability identified as CVE-2025-13703 represents a critical local privilege escalation flaw within VIPRE Advanced Security for PC, a widely deployed endpoint protection solution. This vulnerability stems from improper permission assignment during the product installation process, creating a persistent security weakness that can be exploited by attackers who have already gained low-privileged access to a target system. The flaw specifically affects the installer component where incorrect folder permissions are assigned, allowing malicious actors to manipulate system resources and elevate their privileges to the highest system level. This represents a significant concern for enterprise environments where VIPRE Advanced Security is deployed, as it provides a clear attack pathway for privilege escalation that could lead to complete system compromise.
The technical root cause of this vulnerability lies in the installer's handling of directory permissions, which creates a dangerous misconfiguration in the file system access controls. When VIPRE Advanced Security is installed, certain directories are created with permissions that allow arbitrary users to modify or execute files within these locations. This misconfiguration falls under CWE-276, which specifically addresses incorrect permission assignment in software installations. The vulnerability creates a path where an attacker with local user access can manipulate files in these incorrectly permissioned directories, ultimately allowing them to execute code with SYSTEM privileges. The installer's failure to properly implement least privilege principles during the installation process creates this exploitable condition, making it a prime target for attackers seeking to escalate their access level within the system.
The operational impact of this vulnerability extends beyond simple privilege escalation, as it provides attackers with complete system control through the execution of arbitrary code with SYSTEM privileges. Once an attacker successfully exploits this vulnerability, they can perform actions such as installing additional malware, modifying system files, creating new user accounts, accessing sensitive data, and disabling security controls. This capability directly maps to several ATT&CK techniques including privilege escalation through exploitation of software vulnerabilities and execution through legitimate system processes. The vulnerability's exploitation requires only local access to the system, making it particularly dangerous in environments where physical access or initial compromise is achievable through social engineering, phishing, or other attack vectors. Organizations running affected versions of VIPRE Advanced Security face significant risk of full system compromise, especially when considering that the vulnerability can be exploited by attackers who already have low-privileged access to the target system.
Mitigation strategies for this vulnerability should focus on immediate remediation through official vendor patches and updates, as well as implementing additional security controls to limit the attack surface. Organizations should prioritize patch management and ensure that all instances of VIPRE Advanced Security are updated to versions that address the incorrect permission assignment issue. System administrators should also conduct thorough permission audits to identify and correct any similar misconfigurations in other installed software. The vulnerability highlights the importance of proper installer security practices and adherence to security best practices such as implementing least privilege access controls and conducting security reviews of installation processes. Additionally, network segmentation and monitoring should be enhanced to detect potential exploitation attempts, as this vulnerability could be used as a persistence mechanism following initial compromise. Organizations should also consider implementing application whitelisting policies and monitoring for unauthorized file modifications in system directories to detect potential exploitation attempts.
