CVE-2000-0119 is a vulnerability identified in the default configurations of McAfee Virus Scan and Norton Anti-Virus products dating back to 1999. The core issue arises because these antivirus solutions, in their default setup, do not scan files located within the RECYCLED folder, which is the directory used by the Windows Recycle Bin utility to temporarily store deleted files. This oversight allows attackers to place malicious code or malware within this folder, effectively bypassing virus detection mechanisms. Since the RECYCLED folder is typically hidden and trusted by users and security software alike, malicious files stored here can persist undetected on the system. The vulnerability is rated with a CVSS score of 7.2 (high severity) with vector AV:L/AC:L/Au:N/C:C/I:C/A:C, indicating that exploitation requires local access but has low attack complexity and no authentication. Successful exploitation can lead to full compromise of confidentiality, integrity, and availability of the affected system. Although this vulnerability is over two decades old and no patches are available, it highlights a fundamental gap in antivirus scanning logic that could be exploited if legacy systems or outdated antivirus versions are still in use. No known exploits in the wild have been reported, but the risk remains for environments that have not updated or replaced these antivirus products. The vulnerability affects Windows systems running these antivirus products with default configurations that exclude scanning the RECYCLED folder.

For European organizations, the impact of this vulnerability depends largely on the presence of legacy Windows systems running outdated versions of McAfee Virus Scan or Norton Anti-Virus with default settings. If such systems exist, attackers with local access could hide malware in the RECYCLED folder, evading detection and potentially leading to data breaches, system corruption, or ransomware deployment. The compromise of confidentiality, integrity, and availability could affect sensitive corporate data, disrupt business operations, and damage organizational reputation. Critical infrastructure or sectors with legacy systems, such as manufacturing, healthcare, or government agencies, may be particularly vulnerable. Although modern antivirus solutions and updated configurations mitigate this risk, organizations that have not maintained endpoint security hygiene remain exposed. The local access requirement limits remote exploitation, but insider threats or attackers who gain initial foothold through other means could leverage this vulnerability to escalate privileges or maintain persistence.

Given that no patch is available for this specific vulnerability, European organizations should take the following practical steps: 1) Audit and inventory all endpoints to identify any legacy Windows systems running outdated versions of McAfee Virus Scan or Norton Anti-Virus. 2) Immediately upgrade or replace these antivirus products with current versions that include comprehensive scanning of all system folders, including the RECYCLED directory. 3) Configure antivirus solutions to perform full system scans, explicitly including hidden and system folders such as RECYCLED and Recycler. 4) Implement endpoint detection and response (EDR) tools that monitor for suspicious activity within system folders and unusual file modifications. 5) Enforce strict access controls and monitoring to prevent unauthorized local access, reducing the risk of exploitation. 6) Educate users and administrators about the risks of relying on default antivirus configurations and the importance of regular updates and scans. 7) Regularly review and update security policies to ensure legacy vulnerabilities are addressed and mitigated. These steps go beyond generic advice by focusing on legacy system identification, configuration hardening, and enhanced monitoring specific to this vulnerability's exploitation vector.
