Privileged OS command execution
Published Aug 11, 2023 · Updated Oct 1, 2024
OS command injection in Genians Genian NAC and Genian ZTNA allows local users with administrative privileges to modify system data. The vendor associates the flaw with Genian Update server interactions and lists Policy Server, Network Sensor, and Agent as affected components, but does not disclose the command-building locus or the untrusted field passed to it. Local administrative access is required, and the published record limits the reported consequence to modification without data disclosure or service interruption.
