CVE-2025-52837 is a vulnerability classified under CWE-64 (Improper Neutralization of XPath Expressions) affecting Trend Micro Password Manager (Consumer) version 5.8.0.1327 and earlier. The flaw arises from insecure handling of Windows shortcut (.LNK) files, which can be manipulated by attackers to follow symbolic links improperly. This allows an attacker with limited privileges to delete arbitrary files or folders on the system, thereby escalating their privileges. The vulnerability exploits the way the software processes .LNK files, enabling abuse of symbolic links to bypass intended access controls. The CVSS v3.1 score of 7.8 reflects a high severity due to the combination of local attack vector, low attack complexity, required privileges, and no user interaction needed. The impact spans confidentiality, integrity, and availability, as attackers can delete critical files and gain elevated privileges. Although no public exploits have been reported, the vulnerability poses a significant risk to users of the affected software, especially in environments where local access is possible. Trend Micro has not yet released a patch, so mitigation currently relies on workarounds and system hardening.

The vulnerability allows attackers with limited local access to escalate privileges by deleting arbitrary files or folders, potentially including system or security-critical files. This can lead to full system compromise, unauthorized access to sensitive password data, and disruption of services relying on the password manager. The integrity and availability of the system are at high risk, as attackers can manipulate or remove files to disable security controls or cause denial of service. Confidentiality is also impacted because gaining elevated privileges may expose stored credentials or other sensitive information. Organizations relying on Trend Micro Password Manager in enterprise or consumer environments face increased risk of targeted attacks, insider threats, or malware leveraging this vulnerability to gain persistence and control. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future exploitation.

Until an official patch is released by Trend Micro, organizations should implement strict file system permissions to limit the creation and manipulation of symbolic links and .LNK files by unprivileged users. Employ application whitelisting and endpoint protection solutions to monitor and block suspicious file operations involving shortcuts. Restrict local user privileges to the minimum necessary and audit file deletion events closely. Consider isolating or restricting the use of Trend Micro Password Manager on critical systems. Regularly back up important data to enable recovery from malicious deletions. Once available, promptly apply the vendor's security update to remediate the vulnerability. Additionally, educate users about the risks of local exploitation and enforce strong access controls to reduce the attack surface.
