CVE-2020-15592
SteelCentral Aternity Agent before 11.0.0.120 on Windows allows Privilege Escalation via a crafted file.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.85%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
SteelCentral Aternity Agent before 11.0.0.120 on Windows allows Privilege Escalation via a crafted file. 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. The remotely callable methods from remotable objects available through interprocess communication allow loading of arbitrary plugins (i.e., C# assemblies) from the "%PROGRAMFILES(X86)%/Aternity Information Systems/Assistant/plugins” directory, where the name of the plugin is passed as part of an XML-serialized object. However, because the name of the DLL is concatenated with the “.\plugins” string, a directory traversal vulnerability exists in the way plugins are resolved.
