CVE-2022-50791
Estado: ModificadaAlta (8.5)—
SOUND4 IMPACT/FIRST/PULSE/Eco <=2.x contains a conditional command injection vulnerability that allows local authenticated users to create malicious files in the /tmp directory. Unauthenticated attackers can execute commands by making a single HTTP POST request to the vulnerable ping.php script, which triggers the malicious file and then deletes it.
