Contractor State License Schools (CSLS) has been helping its construction professionals pass the California contractor licensing exam for 30 years. CSLS has several legacy ColdFusion applications that require ongoing ColdFusion expertise and support. They partnered with WRIS to help secure, troubleshoot and upgrade their system. During the initial discovery, we identified security vulnerabilities which required server patches. We also performed ColdFusion hotfix installations to minimize any future ColdFusion server vulnerabilities. Several bugs were addressed and we upgraded an internal application used to enroll new students. The site is now running smoothly, but additional improvements are planned for the near future.
