This affects an unknown functionality of the component Environment Variable Handler. The manipulation of the argument FW_NAT.IN_IP with an unknown input leads to a injection vulnerability. CWE is classifying the issue as CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. This is going to have an impact on availability. The summary by CVE is:

A low privileged remote attacker can perform configuration changes of the firewall services, including packet forwarding or NAT through the FW_NAT.IN_IP environment variable which can lead to a DoS.

The weakness was released by Andrea Palanca as VDE-2024-039. The advisory is shared at cert.vde.com. This vulnerability is uniquely identified as CVE-2024-43390 since 08/12/2024. The exploitability is told to be easy. It is possible to initiate the attack remotely. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1055 for this issue.
