描述
PrintDemon (CVE-2020-1048) Privilege Escalation
介绍
# printDemon2system (CVE-2020-1048)
### PrintDemon privilege escalation to SYSTEM
PrintDemon was a logic vulnerability in the Windows Print Spooler service (**spoolsv.exe**).
The vulnerability was in the way the spooler handled print jobs to files, and when exploited allowed arbitrary writing to the file system as the SYSTEM user.
An example exploit of this vulnerability includes overwriting the *PrintConfig.dll* in the DriverStore directory, which is then loaded by **spoolsv.exe** that is running under the SYSTEM user context, when an XPS Print Job is started (as shown in this repository).
