Description
The NGINX Agent config_dirs directive allows a low-privileged attacker to gain limited read and write access to files outside of the designated secure directory. The config_dirs directive required for this issue can also be configured through NGINX Instance Manager. A successful exploit may allow an attacker to cross a security boundary. Impact: A remotely authenticated low-privileged attacker could gain limited read and write access outside of the list of directories specified in the NGINX Agent configuration. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
