The U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) have released a joint advisory warning that Russia-backed threat actors hacked the network of an unnamed non-governmental entity by exploiting a combination of flaws.

"As early as May 2021, Russian state-sponsored cyber actors took advantage of a misconfigured account set to default [multi-factor authentication] protocols at a non-governmental organization (NGO), allowing them to enroll a new device for MFA and access the victim network," the agencies said.

Microsoft has assigned CVE-2021-34527 to the print spooler remote code execution vulnerability known as "PrintNightmare" and confirmed that the offending code is lurking in all versions of Windows.

The megacorp said it was still investigating whether the vulnerability was exploitable in every version, but domain controllers are indeed affected.

Microsoft also confirmed that this nasty was distinct from CVE-2021-1675, which was all about a different attack vector and a different vulnerability in RpcAddPrinterDriverEx(). The June 2021 Security update dealt with that, according to Microsoft, and did not introduce the new badness. That had existed prior to the update.

The Windows giant also confirmed that the PrintNightmare vulnerability was being exploited in the wild.

Microsoft hat Notfallpatches für eine Sicherheitslücke mit dem Namen Printnightmare veröffentlicht. Ein Problem mit dem Druck-Spooler ermöglichte es Angreifern, Code aus der Ferne auszuführen.

Über die Remote Code Execution könnten Angreifer weitere Programme installieren oder Nutzerkonten mit Administratorrechten erstellen. Zunächst war für das Problem kein Patch verfügbar. Offenbar veröffentlichten Sicherheitsforscher versehentlich einen Proof-of-Concept für einen Exploit, der sich weiterhin ausnutzen ließ.
