关键信息 漏洞名称: VestaCP Debian Installer Malicious Backdoor Supply Chain Compromise 严重性: CRITICAL 日期: October 14, 2025 影响范围: - VestaCP commit a3f0fa1 (2018-05-31) < commit ee03eff (2018-06-13) CVE编号: CVE-2018-2517 CWE编号: CWE-506 Embedded Malicious Code CVSS评分: 9.3 CVSS V4向量: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N 参考链接: - Vesta Exploitation Acknowledgement - Kaspersky Labs Technical Analysis - Vesta Forum - Exploitation Chatter - VestaCP Debian Installer Patch Commit - VestaCP Compromise Commit - VestaCP Product Site - VestaCP GitHub Repo 发现者: Kaspersky Labs 描述: - VestaCP commit a3f0fa1 (2018-05-31) up to commit ee03eff (2018-06-13) contain embedded malicious code that resulted in a supply-chain compromise. New installations created from the compromised Installer since at least May 2018 were subject to installation of Linux/ChachaDDoS, a multi-stage DDoS bot that uses Lua for second- and third-stage components. The compromise leaked administrative credentials (base64-encoded admin password and server domain) to an external URL during installation and/or resulted in the installer dropping and executing a DDoS malware payload under local system privileges. Compromised servers were subsequently observed participating in large-scale DDoS activity. Vesta acknowledged exploitation in the wild in October 2018.
