2 Nov 2023 Apache ActiveMQ Remote code execution
The Java OpenWire protocol marshaller is vulnerable to Remote Code Execution. This vulnerability may allow a remote attacker with network access to either a Java-based OpenWire broker or client to run arbitrary shell commands by manipulating serialized class types in the OpenWire protocol to cause either the client or the broker (respectively) to instantiate any class on the classpath. Users are recommended to upgrade both brokers and clients to version 5.15.16, 5.16.7, 5.17.6, or 5.18.3 which fixes this issue.
- What to do
- Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
- Fixed in (NVD)
- apache activemq 5.18.3, apache activemq legacy openwire module 5.18.3, apache activemq 5.17.6, apache activemq legacy openwire module 5.17.6, apache activemq 5.16.7 and 3 older

1 May 2023 Apache Log4j2 Remote code execution
It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-default configurations. This could allows attackers with control over Thread Context Map (MDC) input data when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix this issue by removing support for message lookup patterns and disabling JNDI functionality by default.

25 Mar 2022 VMware Tanzu Spring Data Commons Remote code execution
Spring Data Commons, versions prior to 1.13 to 1.13.10, 2.0 to 2.0.5, and older unsupported versions, contain a property binder vulnerability caused by improper neutralization of special elements. An unauthenticated remote malicious user (or attacker) can supply specially crafted request parameters against Spring Data REST backed HTTP resources or using Spring Data's projection-based request payload binding hat can lead to a remote code execution attack.

25 Mar 2022 Apache Tomcat Malicious file upload
When running Apache Tomcat 7.0.0 to 7.0.79 on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

Remote code execution in Apache Tomcat 7.0 11 comments10 Dec 2021 Apache Log4j2 Remote code execution
Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.
- What to do
- For all affected software assets for which updates exist, the only acceptable remediation actions are: 1) Apply updates; OR 2) remove affected assets from agency networks. Temporary mitigations using one of the measures provided at https://www.cisa.gov/uscert/ed-22-02-apache-log4j-recommended-mitigation-measures are only acceptable until updates are available.

Building a POC for CVE-2021-404383 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 Struts Input validation flaw
The Jakarta Multipart parser in Apache Struts 2 2.3.x before 2.3.32 and 2.5.x before 2.5.10.1 has incorrect exception handling and error-message generation during file-upload attempts, which allows remote attackers to execute arbitrary commands via a crafted Content-Type, Content-Disposition, or Content-Length HTTP header, as exploited in the wild in March 2017 with a Content-Type header containing a #cmd= string.

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.
