CVE-2020-8599

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Trend Micro Apex One 2019 and OfficeScan XG servers include a vulnerable executable that permits unauthenticated remote attackers to write arbitrary data to any path on the affected system and bypass ROOT login authentication. The flaw carries a CVSS 3.1 base score of 9.8, reflecting network attack vector, low complexity, and full impact on confidentiality, integrity, and availability without requiring user interaction or privileges.

An attacker can therefore send crafted requests directly to the server to place malicious files or overwrite critical components, potentially leading to full system compromise or privilege escalation through the login bypass. No authentication is needed, making the exposure available to any reachable adversary on the network.

Trend Micro has published remediation guidance in solution articles 000244253 and 000245571 that address the vulnerable executable, while the U.S. CISA Known Exploited Vulnerabilities catalog lists CVE-2020-8599 as actively used in the wild, underscoring the need for prompt application of vendor patches or configuration changes recommended in those advisories.
