in-toto vulnerable to Configuration Read From Local Directory
Impact
The in-toto configuration is read from various directories and allows users to configure the behavior of the framework. The files are from directories following the XDG base directory specification [1]. Among the files read is .in_totorc which is a hidden file in the directory in which in-toto is run. If an attacker controls the inputs to a supply chain step, they can mask their activities by also passing in an .in_totorc file that includes the necessary exclude patterns and settings.
RC files are widely used in other systems [2] and security issues have been discovered in their implementations as well [3]. We found in our conversations with in-toto adopters that in_totorc is not their preferred way to configure in-toto. As none of the options supported in in_totorc is unique, and can be set elsewhere using API parameters or CLI arguments, we decided to drop support for in_totorc.
Other Recommendations
Sandbox functionary code as recommended in https://github.com/in-toto/docs/security/advisories/GHSA-p86f-xmg6-9q4x.
