A vulnerability in the 3rd party AV uninstaller module contained in Trend Micro Apex One (on-prem and SaaS), Worry-Free Business Security, and Worry-Free Business Security Services could allow an attacker to manipulate the module to execute arbitrary commands on an affected installation. This vulnerability has been classified as high severity with a CVSS score of 7.2.
Risk to organizations includes potential unauthorized access and command execution, which could lead to data breaches or loss of control over the affected systems. Notably, an attacker must first obtain administrative console access on the target system in order to exploit this vulnerability. Therefore, organizations using these products should take this threat seriously.
Organizations should prioritize patching immediately. The vulnerability was published on September 19, 2023, and has already entered the Known Exploited Vulnerabilities (KEV) catalog as of September 21, 2023, indicating a need for swift action.
Given the potential impact and the exploitability of this vulnerability, it is essential for organizations to ensure they have applied the necessary updates or mitigations as advised by Trend Micro.
Vulnerability Details
The vulnerability exists in the uninstaller module of Trend Micro's products, specifically affecting versions of Apex One and Worry-Free Business Security. The CVSS score of 7.2 indicates a high severity due to its potential for exploitation, and it has been classified under CWE-94, which pertains to code injection vulnerabilities.
The attack vector is categorized as network-based, with a low attack complexity. It requires high privileges, meaning that an attacker must already have administrative access to exploit it successfully. The potential impacts include high confidentiality, integrity, and availability loss.
Technical Analysis
The root cause of this vulnerability lies in the design of the third-party AV uninstaller module, which does not adequately validate or sanitize input. This oversight allows attackers, with the necessary privileges, to leverage this flaw and execute arbitrary commands on the host system.
The attack vector is through the network, with an attacker needing to have high privileges to exploit the vulnerability. There is no requirement for user interaction, making it easier for a malicious actor to execute an attack remotely. The vulnerability's implications are serious, as it can compromise the confidentiality, integrity, and availability of the affected systems.
Risk & Impact Analysis
Organizations using Trend Micro Apex One and Worry-Free Business Security are at risk of significant operational disruptions and potential data breaches due to this vulnerability. The requirement for administrative access means that the risk is elevated in environments where privileged accounts may be targeted.
The potential blast radius is high, as compromised systems could facilitate lateral movement within the network, leading to further exploitation and damage.
Given the CVSS score and the fact that this issue has been added to the KEV catalog, organizations should act quickly. The CVSS score indicates a high level of urgency, and failure to patch could result in severe consequences.
