What is it?

The RealNetworks RealServer administration utility is a software used for managing and streaming audio/video content. This vulnerability allows remote attackers to execute arbitrary commands via a long username and password, posing a significant risk to system integrity and data confidentiality.

Note that this vulnerability does not affect RealPlayer 9 or later versions, nor does it impact other software using the same administration utility. If you don't recognize the name of this specific software, you're probably not affected.
