Sensitive-setting disclosure via exposed process arguments
Published Apr 23, 2020 · Updated Aug 4, 2024
Information disclosure in F5 Networks NGINX Controller before 3.3.0 allows local users to read sensitive settings from process arguments. The optional helper.sh settings script passes sensitive values as command-line arguments instead of keeping them out of process metadata. Exploitation requires local low-privileged access while the helper runs, and the bounded consequence is disclosure of those settings without modification or service interruption.
