Trend Micro addressed multiple vulnerabilities in its Apex One endpoint security product, including actively exploited zero-day flaws.

Trend Micro announced this week the release of security patches to address multiple vulnerabilities in its Apex One endpoint security product, including a zero-day vulnerability, tracked as CVE-2022-40139 (CVSS 3.0 SCORE 7.2), which is actively exploited.

The CVE-2022-40139 flaw is an improper validation issue related to a rollback function, an agent can exploit the vulnerability to download unverified rollback components and execute arbitrary code.

“We have confirmed an improper validation vulnerability in some of the components used for the rollback function of Apex One and Apex One SaaS. This could allow the agent to download unverified rollback components and execute arbitrary code. An attacker would need to be able to log into the product’s administrative console to exploit this vulnerability. Since the attacker must have previously stolen the authentication information for the product’s management console, it is not possible to infiltrate the target network using this vulnerability alone.” reads the advisory published by Trend Micro. “Trend Micro is aware of attacks using this vulnerability (CVE-2022-40139). We recommend updating to the latest build as soon as possible.”

The company pointed out that the vulnerability could be exploited only by an attacker that had access to authentication data.

Trend Micro did not share details of the attacks exploiting this vulnerability.

Below is the list of the vulnerabilities addressed by the security firm:
