"Active Subdomains only" seems not to work in library mode #778
Description
Describe the bug
I'm using subfinder as a go library. I want to use the "-nW" option to only get a list of active subdomains. For that purpose, I use the RemoveWildcard: true parameter. The results of the library are, however, active but also old inactive subdomain. How do I need to configure Subfinder to only get active subdomains?
As a reference, this is how I use subfinder and only get active subdomains:
subfinder -d orbit7.ch -nW
As a library, I configure subfinder as follows:
func subfinderCall(domain string, resultCallback runner.OnResultCallback) (message string) {
runnerInstance, err := runner.NewRunner(&runner.Options{
Threads: 10, // Thread controls the number of threads to use for active enumerations
Timeout: 30, // Timeout is the seconds to wait for sources to respond
MaxEnumerationTime: 10, // MaxEnumerationTime is the maximum amount of time in mins to wait for enumeration
RemoveWildcard: true,
Resolvers: resolve.DefaultResolvers, // Use the default list of resolvers by marshaling it to the config
ResultCallback: resultCallback, // Callback function to execute for available host
})
...
The resultCallback is responsible for collecting the results:
subdomains := make(map[string]common.SubdomainResult)
// list all subdomains for the root target domain
subfinderCall(domain, func(s *resolve.HostEntry) {
subdomainResult := common.SubdomainResult{}
subdomainResult.Host = *s
subdomainResult.HttpxResult = httpxrunner.Result{Failed: true}
subdomains[s.Host] = subdomainResult
})
As a I result, the callback receives the full list of subdomains, i.e. also the inactive ones.
Subfinder version
v2.5.6
Complete command you used to reproduce this
Correct results:
subfinder -d orbit7.ch -nW
All subdomains, even the inactive ones:
runnerInstance, err := runner.NewRunner(&runner.Options{
Threads: 10, // Thread controls the number of threads to use for active enumerations
Timeout: 30, // Timeout is the seconds to wait for sources to respond
MaxEnumerationTime: 10, // MaxEnumerationTime is the maximum amount of time in mins to wait for enumeration
RemoveWildcard: true,
Resolvers: resolve.DefaultResolvers, // Use the default list of resolvers by marshaling it to the config
ResultCallback: resultCallback, // Callback function to execute for available host
})
