CVE-2022-21997 [HIGH] Microsoft Patch Tuesday for Feb. 2022 — Snort rules and prominent vulnerabilities
Microsoft released its monthly security update Tuesday, disclosing 51 vulnerabilities across its large collection of hardware and software.
None of the vulnerabilities disclosed this month are considered “critical,” an extreme rarity for the company’s Patch Tuesdays. Additionally, none of the issues Microsoft patched have been exploited in the wild to this point, nor have they been publicly disclosed.
There are still a few vulnerabilities of note, however, including CVE-2022-21997, CVE-2022-21999 and CVE-2022-22715, which are all privilege elevation vulnerabilities in the Microsoft print spooler service. In the event an exploit is developed, an adversary could use these vulnerabilities to execute code as a system user or higher-level privileges.
There are four other similar vulnerabilit

[HIGH] Microsoft Patch Tuesday, February 2022 Edition
Microsoft today released software updates to plug security holes in its Windows operating systems and related software. This month’s relatively light patch batch is refreshingly bereft of any zero-day threats, or even scary critical vulnerabilities. But it does fix four dozen flaws, including several that Microsoft says will likely soon be exploited by malware or malcontents.
While none of the patches address bugs that earned Microsoft’s most dire “critical” rating, there are multiple “remote code execution” vulnerabilities that Redmond believes are ripe for exploitation. Among those is CVE-2022-22005, a weakness in Microsoft’s Sharepoint Server versions 2013-2019 that could be exploited by any authenticated user.
