CVE-2025-2503 is a vulnerability identified in Lenovo PC Manager, a utility software designed to manage and optimize Lenovo PCs. The vulnerability is categorized under CWE-732, which pertains to incorrect permission assignment for critical resources. Specifically, this flaw allows a local attacker with limited privileges (low-level privileges) to perform arbitrary file deletions with elevated user rights. This means that the attacker can delete files that should normally be protected, potentially including system files or files critical to the operation of the PC or other applications. The vulnerability does not require user interaction and does not involve network access, as indicated by the CVSS vector (AV:L - local access). The attack complexity is low (AC:L), and no authentication beyond low privileges is required (PR:L). The impact on confidentiality is none, but the integrity and availability impacts are high, as critical files can be deleted, potentially leading to system instability or denial of service. The vulnerability is not known to be exploited in the wild as of the publication date (May 30, 2025), and no patches have been linked yet. The affected versions are not explicitly detailed beyond a placeholder '0', suggesting that the vulnerability may affect current or recent versions of Lenovo PC Manager. The vulnerability is medium severity with a CVSS 4.0 score of 6.9, reflecting significant risk but limited by the requirement for local access and low privileges.

For European organizations, this vulnerability poses a risk primarily in environments where Lenovo PCs are widely deployed and Lenovo PC Manager is installed and actively used. The ability for a local attacker to delete arbitrary files with elevated privileges could lead to disruption of business operations, data loss, and potential downtime. In corporate environments, this could facilitate insider threats or lateral movement by malicious actors who have gained limited access to a machine. The deletion of critical files could also impact endpoint security solutions or system stability, increasing the risk of broader compromise or operational disruption. Given the local access requirement, the threat is more pronounced in scenarios where physical access or remote desktop access is possible. Organizations with strict endpoint security policies and limited local user privileges may reduce risk, but those with more permissive environments or shared workstations could be more vulnerable. The lack of known exploits in the wild reduces immediate risk but does not eliminate the potential for future exploitation, especially as the vulnerability becomes publicly known.

1. Immediate mitigation should include restricting local user privileges to the minimum necessary, ensuring that users do not have unnecessary elevated rights on Lenovo PCs. 2. Monitor and audit file system changes and deletions on critical systems to detect suspicious activity indicative of exploitation attempts. 3. Implement application whitelisting and endpoint protection solutions that can prevent unauthorized file deletions or modifications by untrusted processes. 4. Limit physical and remote access to Lenovo PCs, enforcing strong authentication and session controls to reduce the risk of local exploitation. 5. Stay alert for official patches or updates from Lenovo addressing this vulnerability and apply them promptly once available. 6. Consider temporarily disabling or uninstalling Lenovo PC Manager if it is not essential to operations until a patch is released. 7. Conduct user awareness training to reduce the risk of privilege escalation attempts by local users. 8. Employ file integrity monitoring tools to quickly identify unauthorized changes to critical files.
