CVE-2020-4688

Arbitrary command execution via undisclosed injection

Published Jan 20, 2021 · Updated Sep 16, 2024

Command injection in IBM Security Guardium 10.6 and 11.2 allows local users to execute arbitrary commands through an undisclosed vector. IBM has not published the affected component, input, or shell invocation that fails to neutralize command syntax. Local access as an unprivileged user is sufficient; successful exploitation executes commands on the appliance.
