CVE-2020-16268 describes a privilege escalation vulnerability in the MSI installer of 1E Client versions 4.1.0.267 and 5.0.0.745. This flaw allows remote authenticated users or local users to gain elevated privileges by exploiting the repair option, specifically when a TRANSFORM (MST) disables the Nomad module. With a CVSS score of 8.8 (High), the vulnerability is easily exploitable over the network with low attack complexity, potentially leading to full compromise of confidentiality, integrity, and availability. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, the high severity warrants attention.
