CVE-2025-54469
CriticalSummary
Zidentyfikowano podatność w NeuVector, gdzie egzekutor używał zmiennych środowiskowych CLUSTER_RPC_PORT i CLUSTER_LAN_PORT do generowania polecenia wykonywanego za pomocą popen, bez wcześniejszej walidacji ich wartości. To może umożliwić złośliwemu użytkownikowi wstrzyknięcie złośliwych poleceń przez te zmienne w kontenerze egzekutora.
Risk Assessment
Podatność ta stwarza ryzyko wykonania nieautoryzowanych poleceń w kontenerze egzekutora, co może prowadzić do przejęcia kontroli nad systemem lub wycieku danych. Organizacje powinny być świadome potencjalnych zagrożeń związanych z nieodpowiednią walidacją danych wejściowych.
Recommendation
Zaleca się wprowadzenie walidacji i sanitizacji wartości zmiennych środowiskowych CLUSTER_RPC_PORT i CLUSTER_LAN_PORT przed ich użyciem w poleceniach shell. Należy również rozważyć ograniczenie uprawnień kontenera egzekutora, aby zminimalizować potencjalne skutki ataku.

Original NVD description (English source)
A vulnerability was identified in NeuVector, where the enforcer used environment variables CLUSTER_RPC_PORT and CLUSTER_LAN_PORT to generate a command to be executed via popen, without first sanitising their values. The entry process of the enforcer container is the monitor process. When the enforcer container stops, the monitor process checks whether the consul subprocess has exited. To perform this check, the monitor process uses the popen function to execute a shell command that determines whether the ports used by the consul subprocess are still active. The values of environment variables CLUSTER_RPC_PORT and CLUSTER_LAN_PORT are used directly to compose shell commands via popen without validation or sanitization. This behavior could allow a malicious user to inject malicious commands through these variables within the enforcer container.
