Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2022-39959. PoCs published by usmarine2141.

AI-analyzed exploit summary The repository describes a local privilege escalation (LPE) vulnerability in Panini Everest Engine 2.0.4 due to an unquoted service path. An attacker can exploit this by placing a malicious executable in the unquoted path, which gets executed with SYSTEM privileges upon service restart or system reboot.

Description

Panini Everest Engine 2.0.4 allows unprivileged users to create a file named Everest.exe in the %PROGRAMDATA%\Panini folder. This leads to privilege escalation because a service, running as SYSTEM, uses the unquoted path of %PROGRAMDATA%\Panini\Everest Engine\EverestEngine.exe and therefore a Trojan horse %PROGRAMDATA%\Panini\Everest.exe may be executed instead of the intended vendor-supplied EverestEngine.exe file.
