SSL certificate vulnerabilities
Certificate name mismatch
- The SSL certificate mismatch means that the domain name of the website does not match the domain name which has been mentioned in the SSL certificate. It is essential that website domain name must match with the domain name in the SSL certificate. For instance, a website domain name delcorpdata.com.au should be mentioned exactly in the SSL certificate which is delcorpdata.com.au. If domain name of the website is delcorpdata.com.au and in the SSL certificate the domain name is delcorpdata.com then it is known as certificate name mismatch and name mismatch error will be displayed on the screen. The client or user will experience name mismatch error cause of some reasons such as self-signed certificates, exact domain name misspelled and wrong type of SSL certificate.
- Certificate Authority issued certificates should be used and certificate must revive the name of the domain and should be spelled appropriately.
- The issue with internal names is that the Certificate Authorities (CA) will not provide certificates for the internal names and internal name cannot be validated whereas it cannot be substantiated extraneously.
- A public CA signed certificates should be used to overcome the problem of confusion made by browser. The companies’ employees should be aware of such situations and try to avoid them because it can turn into a security breach.
Missing or Misconfigured fields and values in certificates
- Some of the certificates do not have the requisite information which can cause a problem of distrust website because the browser will display the warning message on the screen. The missing or misconfigured values and fields in SSL certificates can halt the applications to work appropriately.
- The SSL certificates should be renewed or reissued with the addition of missing or misconfigured values and fields, and these certificates should also be provided by genuine or trustworthy Certificate Authority (CA) only.
