A vulnerability was found in Trustwave’s ModSecurity project due to an inefficient algorithmic complexity flaw. This issue is present in four transformation actions: removeWhitespace, removeNull, replaceNull, and removeCommentsChar. By sending a maliciously crafted HTTP request, an attacker could trigger worst-case performance, causing a denial of service.
