Demo Examples

Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection')

CWE-90

The code below constructs an LDAP query using user input address data:


               
NamingEnumeration answer = context.search(searchBase, searchFilter, searchCtls);

Because the code fails to neutralize the address string used to construct the query, an attacker can supply an address that includes additional LDAP queries.
