Security researchers accidentally leak PrintNightmare remote execution vulnerability in Windows print spooler
Security researchers have inadvertently leaked details of a critical Windows print spooler vulnerability, dubbed PrintNightmare, along with a proof-of-concept. The flaw -- said be a Stuxnet-style zero-day -- can be exploited to completely compromise a Windows system.
Microsoft issued a patch for CVE-2021-1675, described as a "Windows Print Spooler Elevation of Privilege Vulnerability" last Patch Tuesday, and this is when things went wrong. Having seen that this patch had been published, security researchers then released technical details of what they thought was the same vulnerability, along with a proof-of-concept. But they had in fact released information about a different -- albeit similar -- vulnerability.
