CVE-2023-44857Public exploitNetwork attack vector

Authenticated code execution via crafted acu_web script

Published Apr 12, 2024 · Updated Aug 2, 2024

Code injection in Cobham Satcom SAILOR 600 VSAT Ku 164B019 allows remote authenticated users to execute arbitrary code via acu_web. The acu_web component passes a crafted script to sub_21D24 without neutralizing code syntax, causing attacker-controlled instructions to execute. Low-privileged network access is required, and successful exploitation compromises appliance confidentiality and integrity without a reported service interruption.
