Hey everyone, I’m trying to figure out how to run root-level commands through my Telegram Bot. I’ve set up a webhook that receives HTTPS requests from the bot, but it’s running as the www-data user. This means I can’t execute commands that need root privileges.
Here’s what I’ve tried so far:
I made a simple bash script called terminate.sh:
#!/bin/bash
terminate -15 $1
In my PHP code, I’m calling it like this:
exec('terminate.sh ' . $processIdFromBot);
The script permissions are:
-r-xr-x--- 1 root www-data 28 Dec 18 10:15 terminate.sh*
I even moved the script to /tmp, but no luck. I keep getting this error:
/tmp/terminate.sh: 3: terminate: Operation not permitted
Any ideas on how I can safely run these privileged commands through the bot? I’m open to alternative approaches if this isn’t the best way to do it. Thanks in advance for your help!
yo, running root commands through a bot is pretty sketchy. maybe try setting up a separate service that runs as root and listens for requests from ur webhook? that way u can keep the privileged stuff isolated. it’s a bit more work to set up but way safer in the long run. just make sure to lock down the communication between em so nobody can mess with it
I’ve encountered similar issues with executing privileged commands remotely. In my case, the most secure solution was to set up a separate daemon running as root that listens on a Unix socket, allowing the webhook to communicate securely.
I created a simple Python daemon that runs as root and listens for incoming requests on the socket. I then modified my webhook so that, instead of executing commands directly, it sends its requests to the daemon. Within the daemon, I implemented strict validation to ensure that only authorized commands are executed.
This setup effectively isolates privileged operations from the web-facing components. Although it took some time to configure, the system has been reliable for months. It’s important to thoroughly secure and test the socket communication to avoid potential exploits.
Running root-level commands through a Telegram Bot is risky business. Instead of directly executing privileged commands, consider setting up a separate daemon that runs with root privileges and handles such operations. First, create a daemon service that operates as root. Then, establish a secure communication channel (for example, a Unix socket) between your webhook and the daemon. With this setup, your webhook can send command requests to the daemon, which can validate and execute them securely. Though complex to implement, this method enhances security by isolating privileged operations from web-facing components.
