CVE-2021-33581Network attack vector

Authenticated TCP service access via unchecked PPM URL

Published Mar 30, 2022 · Updated Aug 3, 2024

Server-side request forgery in Software AG MashZone NextGen 10.7 GA and earlier allows remote authenticated users to access arbitrary TCP services. The /mashzone/mzservices/admin/getppmversion endpoint passes its url parameter to an outbound HTTP connection without restricting the destination. Administrative access is required, and the server can be used to reach TCP services otherwise inaccessible to the requester.
