What vulnerability is associated with default administrative credentials being misconfigured in software?

The vulnerability associated with default administrative credentials being misconfigured in software is classified as a security misconfiguration. This type of vulnerability occurs when the security settings of a system are not properly configured, leading to potential exposure to unauthorized access or data breaches.

Default administrative credentials are often set to standard usernames and passwords (like "admin" or "password") out of the box. If these credentials are not changed or secured after installation, attackers can easily exploit this oversight to gain unauthorized access to the system. This clearly illustrates how a failure to adequately configure security settings can leave systems vulnerable to exploitation.

Rather than addressing specific weaknesses like cryptography or handling exceptions, security misconfiguration specifically highlights the risks arising from improperly implemented access controls, making it the most relevant choice in this context.
