CVE-2020-8949 is a remote OS command injection vulnerability affecting multiple Gocloud device firmware versions, including S2A_WL 4.2.7.16471, S2A 4.2.7.17278, S2A 4.3.0.15815, S2A 4.3.0.17193, S3A K2P MTK 4.2.7.16528, S3A 4.3.0.16572, and ISP3000 4.3.0.17190. The flaw is present in the web-based diagnostic ping functionality, where attacker-controlled input is incorporated into a shell command without proper neutralization of shell metacharacters. By supplying crafted input to the ping operation, a remote attacker can break out of the intended command context and append arbitrary operating system commands for execution by the underlying system shell.
