You can protect your organization from RCE vulnerabilities by applying updates as soon as they become available. RCE vulnerabilities can be exploited when a user opens a malicious email or when a user visits a malicious website. An attacker could convince a user to visit a malicious website or email by tricking the user into clicking a link, opening an attachment, or entering in to a malicious website.

Network Protocol Vulnerabilities
There are many different types of vulnerabilities that can be exploited by attackers. Network protocol vulnerabilities are one type of vulnerability that can be found in the network layer and affects communication between the client and the server. This is a very common type of vulnerability for organizations to encounter.
These vulnerabilities affect application layer protocols such as HTTP, SMTP, and FTP, which can be exploited when a user opens an email attachment or visit a website. An attacker could convince a user to visit a malicious website or email by tricking the user into clicking a link, opening an attachment, or entering in to a malicious website.
What is remote code execution?
Remote code execution refers to the ability of an attacker to execute arbitrary commands on a computer that is running vulnerable software. This vulnerability is present when the software does not perform proper validation, so attackers can exploit this vulnerability and gain remote control of a targeted computer.
RCE vulnerabilities are very dangerous because they allow malicious attackers to execute arbitrary code remotely over the internet from anywhere in the world. For example, if an attacker exploits one of these vulnerabilities on your organization’s website, they could steal data or cause a denial-of-service attack on your website.
DNS Rebinding Vulnerability - CVE-2022-1518
The dns rebinding vulnerability is a flaw in the BIND DNS server that can be exploited by a malicious user to exploit the vulnerable system. The vulnerability allows an attacker to intercept traffic from a vulnerable system and redirect it to another website of their choice. To protect your organization from this vulnerability, follow these recommendations:
1) Install the latest version of BIND available for your operating system
2) Update your router configurations so that all client devices are set up with at least a private IP address range
3) Turn on DNS forwarding for your organization’s domain name
4) Use IPsec VPNs or network firewalls to allow traffic through specific ports only when needed.
RCE Vulnerability Types
There are three types of RCE vulnerabilities: Local File Inclusion, Cross-site Scripting (XSS), and Remote Code Execution (RCE).
Exploitability Index
Exploitability index is a metric that measures the risk of an exploit being successful. A high value indicates more risk, while a low value indicates less risk. The exploitability index can be determined by taking into account some of the following factors:
- The severity of the vulnerability
- The difficulty in exploiting the vulnerability
- The likelihood that the vendor will fix the vulnerability
- Others factors specific to each security category
If you are still unsure, then we recommend using our NVD search engine to identify and evaluate CVE identifiers. You can protect your organization from RCE vulnerabilities by applying updates as soon as they become available.
