Deeper analysis
TOTOLink A860R firmware version V4.1.2cu.5182_B20201027 contains a command injection vulnerability in the Main function. The flaw, identified as CVE-2022-25083 with CWE-78, allows arbitrary command execution through the QUERY_STRING parameter and is rated 9.8 on CVSS 3.1 for network attack vector, low complexity, and no required privileges or user interaction.
An unauthenticated remote attacker can supply a malicious QUERY_STRING value to the affected router and execute operating-system commands, resulting in full device compromise including potential persistence, data exfiltration, or use as an attack pivot. No authentication or local access is needed, making the exposure available to any party that can reach the device over the network.
