Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where 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. In Nilsteampassnet/teampass, 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

nilsteampassnet/teampass prior to 3.0.9 is vulnerable to code injection. A malicious user could potentially rename a folder with a payload containing malicious code. This could result in an attack on an admin who edits the folder, as the payload could execute upon the admin's interaction with the folder. This attack could potentially allow the attacker to gain unauthorized access to the admin's system or steal sensitive information, or it could force admin to get redirected to a website controlled by the attacker.
