  author: amit-jd
  severity: medium
  description: |
    Microweber before 1.2.12 is susceptible to integer overflow. The application allows large characters to insert in the input field 'first & last name,' which can allow an attacker to cause a denial of service via a crafted HTTP request.
  impact: |
    Successful exploitation of this vulnerability could lead to remote code execution or denial of service.
  remediation: First name and last name input should be limited to 50 characters or maximum 100 characters.
