CVE-2017-6543

CVE-2017-6543 describes a critical vulnerability in Tenable Nessus before version 6.10.2 (and Tenable Appliance before 4.5.0) on Windows installations, allowing an authenticated attacker to upload a malicious file and write it to arbitrary system locations, potentially leading to elevated privileges after a system reboot. This vulnerability carries a CVSS v3 score of 7.3 (HIGH), indicating a local attack vector with low complexity, requiring user interaction, and resulting in high impact to confidentiality, integrity, and availability. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, the potential for privilege escalation makes patching crucial for affected Windows systems.
