Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1188: Initialization of a Resource with an Insecure Default, where the product initializes or sets a resource with a default that is intended to be changed by the product's installer, administrator, or maintainer, but the default is not secure. In Github.com/bpg/terraform provider proxmox, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

> Note: It is uncertain whether this constitutes a vulnerability or should be filed as an issue instead. ### Summary In the SSH configuration documentation, the sudoer line that was suggested can be escalated to edit any files in the system. ### Details The following line were suggested for addition in the sudoers file: ```bash terraform ALL=(root) NOPASSWD: /usr/bin/tee /var/lib/vz/* ``` But this is highly insecure as the folder can be escaped using `../` and any files can be edited on the system. ### PoC Using a `terraform` user with the previously mentioned line in the `/etc/sudoers` file, a `/etc/sudoers.d/sudo` file can be added using this command: `echo "ALL=(ALL) NOPASSWD:ALL" | tee /var/lib/vz/../../../etc/sudoers.d/sudo` This grants access to the full root of the node. ### Impact This breaches the access limits of the Terraform user. ### Suggested workaround Use a strict regex on the command to allow only the names that should be pushed by this user. Example for cloudinit yaml files: ```bash terraform ALL=(root) NOPASSWD: /usr/bin/tee /var/lib/vz/snippets/[A-Za-z0-9-]*\\.yaml ```
