CVE-2020-15418
In short
Veeam ONE improperly handles XML files, allowing attackers to read sensitive files from the server without needing to log in. An attacker can craft a malicious XML document that tricks the system into accessing and exposing confidential data.
Technical detail
An XXE (XML External Entity) vulnerability in the SSRSReport class of Veeam ONE 10.0.0.750_20200415 permits unauthenticated remote attackers to disclose arbitrary file contents with SYSTEM privileges. The vulnerability stems from insufficient validation of XML external entity references; a crafted document with a URI reference causes the parser to fetch and embed the resource contents, enabling information disclosure.
