An attacker who successfully exploited this vulnerability could read arbitrary files via an XML external entity (XXE) declaration. Here's how Microsoft described the vulnerability:Īn information disclosure vulnerability exists in the Remote Desktop Connection Manager (RDCMan) application when it improperly parses XML input containing a reference to an external entity. The vulnerability was assigned the ID CVE-2020-0765 and the latest RDCMan v2.82 addresses the issue. Mark Russinovich, CTO of Microsoft Azure and co-creator of the Sysinternals utility suite, confirmed that RDCMan wouldn't be abandoned and it will now be a part of Sysinternals.Įarlier today, Microsoft also updated its CVE for the security issue found in RDCMan, stating that the problem has been fixed.

However, earlier this year in February, it had a change of heart. Back in March last year, Microsoft said it will deprecate its Remote Desktop Connection Manager (RDCMan) after a security vulnerability was found in the software.
