Miggo AIRoot Cause Analysis
The vulnerability stems from improper neutralization of the username parameter in LDAP queries. The /login endpoint's authentication flow would logically involve an LDAP filter construction using user input. Given the CWE-74 classification and the LDAP injection vector, the most likely vulnerable code is the LDAP authentication handler that builds the filter string without applying proper escaping (e.g., using fmt.Sprintf("(cn=%s)", username) instead of ldap.EscapeFilter). The function name and location are inferred from standard Traffic Control project structure and authentication implementation patterns.
