CVE-2022-36554Network attack vector

Root command execution via undisclosed CLI input

Published Aug 29, 2022 · Updated Aug 3, 2024

Command injection in Hytec Inter HWL-2511-SS firmware 1.05 and earlier allows remote attackers to execute commands with root privileges. Public disclosures identify the CLI implementation as the vulnerable locus but do not identify the accepted input, invoked command, or missing validation. Network access is sufficient without authentication or user interaction, and successful exploitation grants complete command execution as root.
