CVE-2022-40139: Improper validation of some components used by the rollback mechanism in Trend Micro Apex One and Trend Micro Apex One as a Service clients

Noroxi assessment

Priority: Plan (action score 59/100)

  • CISA has confirmed exploitation in the wild (Sep 15, 2022). Remediation deadline for US federal agencies: Oct 6, 2022.
  • Probability of exploitation in the next 30 days: 3.4% (FIRST EPSS); higher than 88.9% of all records.
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

Improper validation of some components used by the rollback mechanism in Trend Micro Apex One and Trend Micro Apex One as a Service clients could allow a Apex One server administrator to instruct affected clients to download an unverified rollback package, which could lead to remote code execution. Please note: an attacker must first obtain Apex One server administration console access in order to exploit this vulnerability.
