Common Vulnerabilities and Exposures (CVE) are still important to understand and protect against in the constantly changing field of cybersecurity. Recent events in 2023 have made it even more clear how important it is to deal with CVEs. Atlassian Confluence has a serious vulnerability called CVE-2023-22515 that affects different versions of the Atlassian Confluence Data Center and Server. This is a well-known example. Remote attackers who weren't authenticated could use this flaw to make fake administrator accounts and get into Confluence instances. The fact that it was used to harm shows how complex and changing cyber risks are today.

Also, in 2022, many CVEs were regularly used against big companies like VMware, F5 Networks, Microsoft, and Atlassian. These flaws included remote code execution (RCE), privilege escalation, and authentication bypass. This shows how different cybersecurity risks can be.

Also, in December 2023, CISA and its partners put out a joint warning that talked about how IRGC-linked cyber actors were using Unitronics programmable logic controllers (PLCs). This warning is an important reminder of the ongoing threats to cybersecurity, especially in many areas, such as the U.S. Water and Wastewater Systems.

These events show how important it is to always be alert and take preventative steps in defense. Understanding CVEs and what they mean is important for keeping digital systems and networks safe and secure, so it's a key topic for anyone working in cybersecurity.

What is CVE in cyber security?

Common Vulnerabilities and Exposures is what CVE stands for in the world of hacking. People can use it to find and keep track of known flaws in hardware and software. These weaknesses are security holes that have been made public and could let an attacker get into a computer system without permission or do other bad things as well. As well as a standard description, each CVE entry gives a unique vulnerability a standard name.

The main purpose of the CVE system is to make it easy for groups to share information about holes and risks in security and work together to fix these problems. According to the CVE identifiers, it is easier to find vulnerabilities quickly and correctly, talk about them, and take steps to lessen their effects.

Many security experts, researchers, and IT companies use the CVE system to keep track of vulnerabilities and handle the risks that come with them. It is an important part of the bigger ecosystem of cybersecurity tools and methods, which also includes patch management, security alerts, and vulnerability management.

The Cybersecurity and Infrastructure Security Agency (CISA) of the U.S. Department of Homeland Security pays the MITRE Corporation to keep the CVE List up to date. This list is part of a bigger project called the CVE Program, whose goal is to find, describe, and organize publicly known security holes.

Understanding CVE Severity:

A Common Vulnerability and Exposure (CVE) can help you figure out how bad a problem is. Here are some important things to keep in mind:

  • How simple is it to take advantage of?
  • It's important to know how easy it would be for a hacker to take advantage of the weakness. It's a bigger worry if it's easy to take advantage of.

  • What kind of harm could happen?
  • Think about what might happen if the hacker can take advantage of the weakness. The CVE is more important when the possible outcomes are terrible.

  • How often does weakness happen?
  • More people are affected by the CVE if it is found in a lot of systems or software.

  • Is it possible to fix it?
  • Check to see if there is a patch or other way to fix the problem. It's best to highlight a CVE that doesn't have a fix yet.

    These things will help you figure out which CVEs to fix first. If the CVE is very bad, you might even have to delay the release of software or make big changes to make it safer.

Dealing with CVEs) often means using a variety of security tools, each playing a unique role. Here's a simplified outline of some key tools and what they do:

Tools and Approaches Available To Address and Fix CVEs

As you use different security tools to fix a CVE, it can feel like you're juggling a lot of tasks. These tools can often help you see things more clearly and more broadly. When they work together, it can be easier to handle them. Let's look at the available tools. Each one is made to help with a different part of fixing a CVE. This will help you understand what needs to be done without being too busy.

Configuration Management Database (CMDB): Think of this as a giant digital filing cabinet for your company. It stores information about all your tech stuff – like computers, software, and even the connections between them. It's great for keeping track of what you have, but it's not the best for finding network issues or problems with connections.

Cloud Security Tools: These are specialized tools for keeping your cloud info safe. They include:

1. Cloud Access Security Broker (CASB):

It's like a digital bouncer, checking everyone and everything that tries to access your cloud info. It's good at stopping unauthorized access, malware, and other sneaky stuff, but it won't help much with things that aren't in the cloud.

2. Cloud Security Posture Management (CSPM):

This tool is like a security advisor for your cloud setup. It helps find and fix risks in the cloud, but it can't watch the actual data moving in and out in real-time.

3. Cloud Workload Protection Platform (CWPP):

Think of this as a protector for your cloud data, helping protect both cloud and on-premises data. However, it's not great at dealing with app-level security or the core cloud infrastructure.

4. Cloud-Native Application Protection Platform (CNAPP):

This is a more advanced tool mixing CSPM and CWPP features. It works well for finding problems in public clouds, but it has some flaws.

The Identity and Access Management (IAM) tool controls who can see what information based on the level of security danger. It's like a high-tech guard guard. It quickly fixes problems with access, but it's not meant to find new assets or deal with a lot of reports.

Internet of Things (IoT) Security Solutions:

These solutions are made to keep smart devices safe as more of them connect to the internet. They're good at finding these things, but not so good at fixing any problems they might have.

Security Information and Event Management (SIEM):

This is like a command center that gathers security information from different sources, looks for strange behavior, and sets off alarms or takes other actions. It can let you know about problems, but it can't fix the weaknesses themselves.

Network Access Control (NAC):

This tool checks and evaluates every device that tries to join your network, like a security guard at the front door. It works great for finding new devices, but not so well for keeping track of links that are already there or fixing security holes.

Because each of these tools has its own pros and cons, using more than one of them together often gives you a fuller picture and more power over your security.


As we wrap up our look at CVE in cybersecurity, it's important to remember that threats are still out there. In this area, these threats are always changing. The year 2023 has shown how important CVEs are of late. They have important effects on safety.

Because of a certain flaw, people from far away could make admin accounts without being verified. They were able to get into Confluence servers, which was very bad for network security. Patches and strong security steps need to be put in place right away. To protect against these weaknesses, these steps are very important. The fact that CISA, FBI, and MS-ISAC are working together makes this urgency even clearer. They worked together to make people more aware of these problems and give advice on how to fix them.

It is important to stay informed and take the initiative when putting security steps in place. These steps are very important to keep you safe from new cyber dangers. With SafeAeon you can seek adequate assistance for an implication to your digital system. It's becoming more and more important to understand and fix these weaknesses. It is very important for keeping digital systems and networks safe and secure.
