CVE-2025-53378: A missing authentication vulnerability in Trend Micro Worry-Free Business Security Services (WFBSS) agent could have allowed an unauthenticated attacker to remotely take control of the agent on affected installations. Also note: this vulnerability only affected the SaaS client version of WFBSS only, meaning the on-premise version of Worry-Free Business Security was not affected, and this issue was addressed in a WFBSS monthly maintenance update. Therefore no other customer action is required to mitigate if the WFBSS agents are on the regular SaaS maintenance deployment schedule and this disclosure is for informational purposes only.
The exploitability of CVE-2025-53378 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
With low attack complexity and no required privileges, CVE-2025-53378 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2025-53378, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2025-53378, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
