Cryptography / SSL Certificate Chain Contains Rsa Keys Less than 2048 Bits
SSL Certificate Chain Contains RSA Keys Less Than 2048 bits is a type of cryptographic vulnerability (CWE-310) which occurs when an SSL certificate chain contains RSA keys that are less than 2048 bits in length. This type of vulnerability is particularly common in infrastructure environments and can lead to serious security concerns. As per the OWASP Testing Guide, RSA keys that are less than 2048 bits in length can be easily cracked by attackers, allowing them to gain access to sensitive data.
This type of vulnerability can have serious implications for an organization's security. An attacker can use the RSA keys that are less than 2048 bits in length to gain access to sensitive data, which can lead to data breaches and other security incidents. Additionally, this type of vulnerability can also lead to financial losses, as the organization may be held liable for any data that is accessed or stolen as a result of the vulnerability.
In order to mitigate the risk associated with this type of vulnerability, organizations should ensure that all SSL certificates used in their infrastructure have RSA keys that are at least 2048 bits in length. Additionally, organizations should also ensure that they keep their RSA keys up to date, as newer RSA keys may be more secure than older ones.
Below is an example of an RSA key that is less than 2048 bits in length.
