Two zero-days fixed, one actively exploited
This month’s Patch Tuesday fixes two zero-day vulnerabilities, with one actively exploited in attacks.
Microsoft classifies a vulnerability as a zero-day if it is publicly disclosed or actively exploited with no official fix available.
The actively exploited zero-day vulnerability fixed today is jokingly known as ‘DogWalk” and tracked by Microsoft as ‘CVE-2022-34713 – Microsoft Windows Support Diagnostic Tool (MSDT) Remote Code Execution Vulnerability.’
Security researcher Imre Rad discovered this vulnerability in January 2020, but Microsoft decided not to fix it after deeming it not to be a security vulnerability.
However, after the discovery of the Microsoft Office MSDT vulnerability, security researchers once again pushed to have the DogWalk vulnerability fixed as well, which was done as part of today’s updates.
The other zero-day vulnerability is tracked as ‘CVE-2022-30134 – Microsoft Exchange Information Disclosure Vulnerability’ and allows an attacker to read targeted email messages.
Microsoft says that the CVE-2022-30134 vulnerability is publicly disclosed but has not been detected in attacks.
