CVE-2023-48699

Local code execution via evaluated locator configuration

Published Nov 21, 2023 · Updated Aug 2, 2024

Eval injection in fastbots before 0.1.5 allows local users to execute arbitrary Python code through a modified locators.ini file. The locator method in page.py passes locator text returned from the configuration file directly to Python's eval function without validation. Exploitation requires write access to locators.ini and executes code with the privileges and data access of the process using the library.
