It uses an executable running as a high privileged Windows service to perform administrative tasks and collect data from other processes. It distributes functionality among different processes and uses IPC (Inter-Process Communication) primitives to enable the processes to cooperate. Any user in the system is allowed to access the interprocess communication channel AternityAgentAssistantIpc, retrieve a serialized object and call object methods remotely. Among others, the methods allow any user to: (1) Create and/or overwrite arbitrary XML files across the system; (2) Create arbitrary directories across the system; and (3) Load arbitrary plugins (i.e., C# assemblies) from the \"%PROGRAMFILES(X86)/Aternity Information Systems/Assistant/plugins” directory and execute code contained in them.","published":"2020-07-27T14:15:12.000Z","lastModified":"2026-06-17T02:56:53.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":["riverbed/steelcentral aternity agent"],"epss":{"score":0.0044,"percentile":0.38001,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.44%).
