Command execution via unsanitized cmd parameter
Published Sep 6, 2024 · Updated Sep 6, 2024
Command injection in D-Link DI-8100G 17.12.20A1 allows remote attackers to execute arbitrary commands through msp_info.htm. The jhttpd handler sub_457A6C reads the cmd parameter when flag equals cmd, concatenates that value into a command buffer, and passes it to system without neutralizing shell syntax. The published request includes an administrative session cookie, although NVD rates privileges as none, so the precise authentication gate is unresolved; successful exploitation grants command execution on the appliance.
