Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-190: Integer Overflow or Wraparound, where the product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. this occurs when an integer value is incremented to a value that is too large to store in the associated representation. when this occurs, the value may become a very small or negative number. In Microweber/microweber, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Microweber is a new generation CMS with drag and drop. The microweber application allows large characters to insert in the input field "first & last name" which can allow attackers to cause a Denial of Service (DoS) via a crafted HTTP request. The first name & last name input should be limited to 50 characters or max 100 characters
