Detailsinfo

A vulnerability classified as very critical was found in Horilla up to 1.x. Affected by this vulnerability is the function HorillaListView.export_data of the file horilla_views/generic/cbv/views.py of the component Export Data. The manipulation of the argument columns with an unknown input leads to a code injection vulnerability. The CWE definition for the vulnerability is CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Horilla is an HR and CRM software. Prior to 2.0.0, HorillaListView.export_data in horilla_views/generic/cbv/views.py accepts an authenticated user's columns POST parameter, takes field_tuple[1], interpolates it into dynamic_fn_str as Python source, and passes the generated function definition to exec(). A crafted string that remains valid under ast.literal_eval can inject Python syntax into a default argument evaluated during function definition, allowing arbitrary operating-system commands to execute with the application process privileges, including root privileges in the shipped Docker image. This issue is fixed in version 2.0.0.
