CVE-2022-28005
CRITICAL EXPLOITED3cx < 18.0.3.450 - Unauthenticated Path Traversal and Remote Code Execution via Electron Download Directory
Title source: llmExploitation Summary
CVE-2022-28005 has been observed exploited in the wild (reported by VulnCheck KEV).
Description
An issue was discovered in the 3CX Phone System Management Console prior to version 18 Update 3 FINAL. An unauthenticated attacker could abuse improperly secured access to arbitrary files on the server (via /Electron/download directory traversal in conjunction with a path component that uses backslash characters), leading to cleartext credential disclosure. Afterwards, the authenticated attacker is able to upload a file that overwrites a 3CX service binary, leading to Remote Code Execution as NT AUTHORITY\SYSTEM on Windows installations. NOTE: this issue exists because of an incomplete fix for CVE-2022-48482.
