In Linaro Automated Validation Architecture (LAVA) before 2022.11.1, remote code execution can be achieved through user-submitted Jinja2 template. The REST API endpoint for validating device configuration files in lava-server loads input as a Jinja2 template in a way that can be used to trigger remote code execution in the LAVA server.

Detection & IOCs extracted from sources · hover to see the quote

• → The vulnerable REST API endpoint for validating device configuration files in lava-server loads user-submitted input as a Jinja2 template, enabling SSTI-based RCE. Monitor for suspicious Jinja2 template syntax (e.g., `{{`, `{%`) in requests to the device configuration validation endpoint. ↗
• → Target LAVA versions prior to 2022.11.1 are vulnerable. Identify unpatched lava-server instances (pre-2022.11.1) exposed to untrusted users as high-priority targets for detection/patching. ↗

• · Debian scopes this as 'local' impact. Fixed versions are: bookworm/forky/sid fixed in 2023.01-1; bullseye also resolved. Ensure patched package versions are deployed. ↗
