The US Cybersecurity and Infrastructure Security Agency (CISA) has added two privilege elevation vulnerabilities – one in Microsoft Exchange Server and one in Windows – to its Known Exploited Vulnerabilities (KDEV) Catalog. US Federal Civilian Executive Branch Agencies have until January 31 to mitigate the flaws.
Note
- CVE-2022-41080 – an Exchange privilege escalation flaw from last year, can be combined with CVE-2022-41082 to achieve arbitrary code execution. CVE-2023-211674 is the same Windows ALPC privilege escalation flaw addressed in the Jan 10 Windows update we discussed previously. Good news, the patches for these are out, go deploy them. Bad news – you’re still hanging onto those on-premises Exchange servers.
