OutSystems Service Center is vulnerable to a DOM-based Cross-Site Scripting (XSS) attack that can be exploited by a low-privileged attacker via the upload of a file with a malicious filename containing JavaScript code. The vulnerability exists in all locations where a file can be attached and prepared for upload to the server.

This issue was fixed in OutSystems Service Center version 11.41.2

OutSystems Lifetime is vulnerable to Authorization Bypass Through User-Controlled Key vulnerability in ApplicationID parameter. Any authenticated user, can read the Change Log containing actions performed by other users as well as application name of any application.

This issue was fixed in OutSystems Lifetime version 11.28.2.3955

Outsystems Platform Server 11.18.1.37828 allows attackers to cause a denial of service via a crafted content-length value mismatching the body length. NOTE: the Supplier indicates that they are unable to reproduce this.

The Multiple File Upload add-on component 3.1.0 for OutSystems is vulnerable to Unrestricted File Upload. This occurs because file extension and size validations are enforced solely on the client side. An attacker can intercept the upload request and modify a parameter to bypass extension restrictions and upload arbitrary files. NOTE: this is a third-party component that is not supplied or supported by OutSystems.

A DLL hijacking vulnerability has been discovered in OutSystems Service Studio 11 11.53.30 build 61739. When a user open a .oml file (OutSystems Modeling Language), the application will load the following DLLs from the same directory avlibGLESv2.dll, libcef.DLL, user32.dll, and d3d10warp.dll. Using a crafted DLL, it is possible to execute arbitrary code in the context of the current logged in user.

A stored XSS vulnerability was discovered in the ECT Provider in OutSystems before 2020-09-04, affecting generated applications. It could allow an unauthenticated remote attacker to craft and store malicious Feedback content into /ECTProvider/, such that when the content is viewed (it can only be viewed by Administrators), attacker-controlled JavaScript will execute in the security context of an administrator's browser. This is fixed in Outsystems 10.0.1005.2, Outsystems 11.9.0 Platform Server, and Outsystems 11.7.0 LifeTime Management Console.

The ECT Provider component in OutSystems Platform Server 10 before 10.0.1104.0 and 11 before 11.9.0 (and LifeTime management console before 11.7.0) allows SSRF for arbitrary outbound HTTP requests.

An issue was discovered in the Upload Widget in OutSystems Platform 10 before 10.0.1019.0. An unauthenticated attacker can upload arbitrary files. In some cases, this attack may consume the available database space (Denial of Service), corrupt legitimate data if files are being processed asynchronously, or deny access to legitimate uploaded files.

DISPUTED OutSystems Platform 10 through 11 allows ImageResourceDetail.aspx CSRF for content modifications and file uploads. NOTE: The product is self-hosted by the customer, even though it has a .outsystemsenterprise.com domain name.) NOTE: The vendor claims that the independent researcher created the report without any type of validation and that no such vulnerability exists.
