Background
The @accenturecodefoundry/mfe-pot-shared-ui-scds-core package is designed as a simple placeholder for npm, facilitating the management of shared UI components. However, it has been compromised, allowing malicious actors to exploit it for data exfiltration. The package's preinstall hook is particularly vulnerable, executing scripts that can send sensitive information to external servers.
Vulnerability Detail
The vulnerability stems from the preinstall hook in versions 99.99.2, 99.99.4, and 99.99.41 of the package. These versions encode the hostname and username as hexadecimal query parameters and send them to an external server (accenture-npm.azurewebsites.net). This behavior is part of a dependency confusion campaign, where the malicious package is designed to outrank internal packages, potentially leading to data breaches. The malicious code reveals the victim's egress IP and confirms the success of the attack.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall @accenturecodefoundry/mfe-pot-shared-ui-scds-coreIf it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
