VMware vRealize Log Insight Unauthenticated Remote Code Execution
Posted on 11 September 2023
VMware vRealize Log Insights versions 8.x contain multiple vulnerabilities, such as directory traversal, broken access control, deserialization, and information disclosure. When chained together, these vulnerabilities allow a remote, unauthenticated attacker to execute arbitrary commands on the underlying operating system as the root user. This Metasploit module achieves code execution via triggering a RemotePakDownloadCommand command via the exposed thrift service after obtaining the node token by calling a GetConfigRequest thrift command. After the download, it will trigger a PakUpgradeCommand for processing the specially crafted PAK archive, which then will place the JSP payload under a certain API endpoint (pre-authenticated) location upon extraction for gaining remote code execution. Successfully tested against version 8.0.2.
