CVE-2025-69875 is a vulnerability identified in Quick Heal Total Security version 23.0.0, specifically within its quarantine management component. The core issue stems from insufficient validation of file restore paths combined with improper permission handling during the restoration of quarantined files. This flaw allows a low-privileged local user to restore files into protected system directories, which are normally restricted to higher privilege levels. By exploiting this, an attacker can place malicious executables or scripts in locations that the operating system or security mechanisms trust, thereby escalating their privileges from a standard user to potentially SYSTEM or administrator level. The vulnerability does not require network access or remote exploitation, limiting the attack vector to local users with some access to the system. No public exploits have been reported yet, and the vendor has not published patches or detailed advisories at this time. The absence of a CVSS score suggests the vulnerability is newly disclosed and pending further assessment. However, the technical details indicate a serious risk due to the ability to bypass privilege boundaries and compromise system integrity. This vulnerability is particularly concerning for environments where endpoint security software like Quick Heal is deployed and local user accounts are not tightly controlled. Attackers with physical or remote desktop access could leverage this flaw to gain elevated privileges, potentially leading to full system compromise or lateral movement within a network.

For European organizations, the impact of CVE-2025-69875 could be significant, especially in sectors where endpoint security solutions like Quick Heal Total Security are widely used. Successful exploitation allows local attackers to escalate privileges, which can lead to unauthorized access to sensitive data, disruption of critical services, and potential deployment of further malware or ransomware. This undermines the confidentiality, integrity, and availability of affected systems. Organizations with shared workstations, insufficient local user restrictions, or remote access capabilities are at higher risk. The vulnerability could facilitate insider threats or attacks by adversaries who have gained limited access to endpoints. Critical infrastructure, government agencies, and enterprises relying on Quick Heal for endpoint protection may face increased risk of compromise. Additionally, the lack of a current patch means organizations must rely on interim controls, increasing operational complexity and risk exposure until a fix is available.

1. Immediately restrict local user permissions to prevent unauthorized access to the Quick Heal quarantine restore functionality. 2. Implement strict access controls and monitoring on endpoints running Quick Heal Total Security to detect unusual restore operations or file placements in protected directories. 3. Use application whitelisting and integrity monitoring tools to detect unauthorized changes in system directories. 4. Educate users and administrators about the risk of local privilege escalation and enforce least privilege principles. 5. Regularly audit local user accounts and remove unnecessary privileges or accounts. 6. Monitor vendor communications closely for patches or updates addressing this vulnerability and apply them promptly once available. 7. Consider deploying additional endpoint detection and response (EDR) solutions to identify suspicious local activities. 8. In environments where Quick Heal is not critical, evaluate alternative endpoint security products with a stronger security posture until this issue is resolved.
