Detailsinfo

A vulnerability classified as critical has been found in jc21 NGINX Proxy Manager up to 2.9.19 (Firewall Software). This affects an unknown part of the component Access List Handler. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

jc21 NGINX Proxy Manager through 2.9.19 allows OS command injection. When creating an access list, the backend builds an htpasswd file with crafted username and/or password input that is concatenated without any validation, and is directly passed to the exec command, potentially allowing an authenticated attacker to execute arbitrary commands on the system. NOTE: this is not part of any NGINX software shipped by F5.
