| Descrizione | The program obtains environment variable parameters through `getenv`, and only filters backquote characters, without effectively restricting other special symbols that may trigger command execution. An attacker can construct a string similar to `ssdp:all+command` to inject malicious content into the parameters passed to the `lxmldbc_system` function. Because the function uses `sprintf` to splice the command string and executes it through `system`, it eventually leads to a command injection vulnerability, which allows an attacker to achieve remote code execution. This can then achieve malicious attacks such as rebound shells. |
