Trend Micro has addressed multiple vulnerabilities in its Apex Central platform through the release of Patch 4 (B6394). These vulnerabilities, identified by CVE identifiers CVE-2023-32529 through CVE-2023-32537 and CVE-2023-32604 through CVE-2023-32605, affect the Windows platform. The severity of the vulnerabilities ranges from medium to high, with CVSS 3.0 scores ranging from 4.1 to 7.2.
To ensure the security of their systems, users are strongly advised to take appropriate action and apply the necessary updates. The updated version of Apex Central, which includes the fixes for the vulnerabilities, can be downloaded from Trend Micro’s Download Center. It is recommended that customers obtain the latest version of the product to resolve any known issues.
Two of the vulnerabilities, CVE-2023-32529 and CVE-2023-32530, are SQL injection remote code execution vulnerabilities. These vulnerabilities exist in vulnerable modules of Trend Micro Apex Central and can be exploited by authenticated users to execute remote code through SQL injection. However, it is important to note that attackers must first obtain authentication on the target system to successfully exploit these vulnerabilities.
Several other vulnerabilities, CVE-2023-32531 through CVE-2023-32535, are central cross-site scripting (XSS) remote code execution vulnerabilities. These vulnerabilities affect certain dashboard widgets on Trend Micro Apex Central and can be exploited to execute remote code on affected servers. Promptly addressing these vulnerabilities is crucial to mitigate the associated risks.
Additionally, Trend Micro has identified authenticated reflected XSS vulnerabilities, including CVE-2023-32536, CVE-2023-32537, CVE-2023-32604, and CVE-2023-32605. These vulnerabilities are caused by user input validation and sanitization issues in affected versions of Apex Central. Exploiting these vulnerabilities requires the attacker to authenticate to Apex Central on the target system.
To further enhance security, users are advised to review remote access to critical systems and ensure the implementation of up-to-date policies and perimeter security. These measures can provide an extra layer of defense against potential attacks.
Trend Micro would like to express its gratitude to security researchers Poh Jia Hao of STAR Labs SG Pte. Ltd. and Pankaj Kumar Thakur of Green Tick Nepal Pvt. Ltd. for responsibly disclosing these vulnerabilities and working collaboratively to address them. Customers can find more detailed information about these vulnerabilities in the advisories published by Trend Micro’s Zero Day Initiative, namely ZDI-CAN-17688, ZDI-CAN-17690, ZDI-CAN-18872, ZDI-CAN-18871, ZDI-CAN-18876, ZDI-CAN-18874, and ZDI-CAN-18867.
This incident highlights the importance of effective vulnerability management. Organizations worldwide have fallen victim to ransomware attacks, such as those launched by the Cl0p ransomware group, due to faulty vulnerability management. The Cl0p group has been exploiting vulnerabilities in various software, including MOVEit Transfer, to carry out ransomware attacks. In May alone, a significant number of vulnerabilities were reported, with a majority being remotely exploitable. It is essential for organizations to prioritize and address actionable vulnerabilities classified as high severity to prevent significant security breaches.
Failure to manage vulnerabilities effectively has resulted in past attacks, such as the NotPetya attack in 2017, the Triton/Trisis attack in 2017, and the Colonial Pipeline attack in 2021. These incidents highlight the consequences of inadequate management of vulnerabilities and the need for organizations to prioritize cybersecurity measures.
In conclusion, Trend Micro’s prompt release of Patch 4 (B6394) for Apex Central addresses multiple vulnerabilities and provides users with the necessary updates to protect their systems. Users are strongly encouraged to download the updated version of Apex Central from Trend Micro’s Download Center to ensure the resolution of known issues. Additionally, organizations should prioritize vulnerability management efforts and focus on remotely exploitable vulnerabilities with public exploits and viable solutions. By taking these steps, organizations can significantly enhance their cybersecurity posture and reduce the risk of potential security breaches.
