{"id":"CVE-2018-25117","details":"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.","modified":"2026-03-15T14:02:53.090685Z","published":"2025-10-15T02:15:31.580Z","references":[{"type":"WEB","url":"https://vestacp.com/"},{"type":"WEB","url":"https://www.welivesecurity.com/2018/10/18/new-linux-chachaddos-malware-distributed-servers-vestacp-installed/"},{"type":"WEB","url":"https://forum.vestacp.com/viewtopic.php?f=10&t=17641&p=73282"},{"type":"WEB","url":"https://forum.vestacp.com/viewtopic.php?f=10&t=17641&start=180#p73907"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/vestacp-debian-installer-malicious-backdoor-supply-chain-compromise"},{"type":"FIX","url":"https://github.com/outroll/vesta/commit/a3f0fa1501d424477786e3e7150bb05c0b99518f#diff-df8da0c91e9086454c60cd468849630dR1256"},{"type":"FIX","url":"https://github.com/outroll/vesta/commit/ee03eff016e03cb76fac7ae3a0f9d1ef0f8ee35b#diff-df8da0c91e9086454c60cd468849630dL1270"},{"type":"PACKAGE","url":"https://github.com/outroll/vesta"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/outroll/vesta","events":[{"introduced":"0"},{"fixed":"a3f0fa1501d424477786e3e7150bb05c0b99518f"}]},{"type":"GIT","repo":"https://github.com/outroll/vesta","events":[{"introduced":"0"},{"fixed":"ee03eff016e03cb76fac7ae3a0f9d1ef0f8ee35b"}]}],"versions":["0.9.8-10","0.9.8-11","0.9.8-12","0.9.8-13","0.9.8-15","0.9.8-16","0.9.8-17","0.9.8-18","0.9.8-19","0.9.8-20"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-25117.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
