CyberRota Analysis
AI-GeneratedSandboxie-Plus versions prior to 1.17.6 are vulnerable due to improper validation of thread and process identifiers in the GuiServer component, enabling attackers to execute arbitrary code in unsandboxed host processes. This high-severity vulnerability poses a significant risk to users relying on Sandboxie-Plus for isolation, as it can lead to unauthorized access and potential system compromise. Organizations utilizing this software should prioritize upgrading to version 1.17.6 to mitigate the risk.

Original NVD Description
Sandboxie-Plus is an open source sandbox-based isolation software for Windows. Prior to 1.17.6, GuiServer::WndHookRegisterSlave in Sandboxie/core/svc/GuiServer.cpp stores attacker-supplied hthread and hproc fields from a GUI_WND_HOOK_REGISTER request without validating that the thread belongs to the sandboxed process or that the function pointer is in the caller address space, and GuiServer::WndHookNotifySlave then calls OpenThread(THREAD_SET_CONTEXT, FALSE, whk->hthread) and QueueUserAPC((PAPCFUNC)whk->hproc, hThread, (ULONG_PTR)req->threadid) as SYSTEM, allowing a sandboxed process to execute arbitrary code in an unsandboxed host process. This issue is fixed in version 1.17.6.
