3 Nov 2021 Apache HTTP Server Path traversal
It was found that the fix for CVE-2021-41773 in Apache HTTP Server 2.4.50 was insufficient. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue only affects Apache 2.4.49 and Apache 2.4.50 and not earlier versions.

3 Nov 2021 Apache HTTP Server Path traversal
A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue is known to be exploited in the wild. This issue only affects Apache 2.4.49 and not earlier versions. The fix in Apache HTTP Server 2.4.50 was found to be incomplete, see CVE-2021-42013.

3 Nov 2021 Apache Solr Input validation flaw
Apache Solr 5.0.0 to Apache Solr 8.3.1 are vulnerable to a Remote Code Execution through the VelocityResponseWriter. A Velocity template can be provided through Velocity templates in a configset `velocity/` directory or as a parameter. A user defined configset could contain renderable, potentially malicious, templates. Parameter provided templates are disabled by default, but can be enabled by setting `params.resource.loader.enabled` by defining a response writer with that setting set to `true`. Defining a response writer requires configuration API access. Solr 8.4 removed the params resource loader entirely, and only enables the configset-provided template rendering when the configset is `trusted` (has been uploaded by an authenticated user).

About the KEV Catalogue
What is the CISA KEV catalogue?
CISA's list of flaws attackers are known to be using. A flaw is added only with reliable evidence of attacks and a known fix.
Why does it matter more than the CVSS score?
Few CVEs are ever used in attacks. These are, so fix them first, whatever their score.
What is the due date?
The deadline for US federal agencies to fix it (BOD 26-04, which replaced BOD 22-01): as little as three days for recent entries. A sensible deadline for anyone.
Does it apply outside the US?
The deadlines don't, but the flaws are in software used everywhere. If you run it, it applies to you.
What does "used in ransomware" mean?
CISA knows ransomware groups have used the flaw.
How often is it updated?
CISA adds flaws several times a week. CVE Hawk checks hourly and alerts you within half an hour if it's your software.
