Stroom is a data processing, storage and analysis platform. A vulnerability exists starting in version 7.2-beta.53 and prior to versions 7.2.24, 7.3-beta.22, 7.4.4, and 7.5-beta.2 that allows authentication bypass to a Stroom system when configured with ALB and installed in a way that the application is accessible not through the ALB itself. This vulnerability may also allow for server-side request forgery which may lead to code execution or further privileges escalations when using the AWS metadata URL. This scenario assumes that Stroom must be configured to use ALB Authentication integration and the application is network accessible. The vulnerability has been fixed in versions 7.2.24, 7.3-beta.22, 7.4.4, and 7.5-beta.2.

All versions of stroom:stroom-app before 5.5.12 and all versions of the 6.0.0 branch before 6.0.25 are affected by Cross-site Scripting. An attacker website is able to load the Stroom UI into a hidden iframe. Using that iframe, the attacker site can issue commands to the Stroom UI via an XSS vulnerability to take full control of the Stroom UI on behalf of the logged-in user.

Stroom version <5.4.5 contains a XML External Entity (XXE) vulnerability in XML Parser that can result in disclosure of confidential data, denial of service, server side request forgery, port scanning. This attack appear to be exploitable via Specially crafted XML file.
