Sipp authentication example
It uses XML format files to define test scenarios. Register to If CSV file has more than one entry you can increase simultaneous call limit -l option. This scenario expects calls to be answered. Call targets are 3 other UACs configured to auto answer and play wav file single pjsua instance with 3 accounts. Each call is disconnected after 30 s. Call limit is this time smaller than number of CSV entries to avoid multiple calls to single target. Some modification may be needed when calling operator that is using more complex proxy infrastructure.
Little tricky scenario that requires two actual scenario files. Sending unsolicited talk event if supported: causing call to be answered to phone 31 Call is not answered.
SIP digest leak is a SIP phone vulnerability that allows attacker to get digest response from a phone and use it to guess password using brute-force method described first on enablesecurity. Here are required steps:. Assuming that username and realm are known attacker can now use brute-force method to guess user password. If you ever had to make high-load call or even single-call tests with G. Obviously pjsua would be good choice, but it require downloading DirectX SDK, Intel Performance Primitives package and rebuilding from sources, so it would take few hours to get working binary.
Here is. This is actually recorded connection with some voice mail system. Included scenario is UAC call, to get credible load test results you can call i. Simulating two endpoints with single script seems difficult if not impossible, so some tests requre running two or more separate scripts e.
To synchronization between scripts create batch file:. If delay between scripts is needed alternatively pause can be used inside scriptse. Pjsua sleep command allows to pipe commands from prepared text file to pjsua in a timely manner making it possible to use it as limited but very easy to use call generator.
For simple tasks such as sending single SIP message to remote destination sipsak may be handy. Execution rate is combined of rate and period parameters, i.
If limit is reached, sockets are reused. Replaces [service] tag in XML scenario file. By default call is aborted, use ontimeout attribute to take other action. Simple scenario files with usage These scenario files were tested with sipp-win There are few conditions that have to be met to make this scheme work: SIP phone has to respond to authentication challenges sent by other sources than registration server s it is using as a note it works with one hardware phone and one softphone I've tested and those were all user agents I've testedphone SIP port has to accessible to attacker, usally phone will be placed behind the Restricted Cone NAT and port would not be forwarded, attacker would most likely have to know username and authentication realm used by target; for better security you probably should not leave "realm" configuration field of SIP phone empty it could respond to challenges with any realm then making it easier to prepare attackguessing password through brute-fource would be time consuming or almost impossible for more complex passwords.

The server indicates support for NTLM and Kerberos in the challenge and returns the realm and targetname values that it created during initialization, the version of the authentication protocol that it implements, and the Date header field.
The protocol client decides to use Kerberos and creates an SA with data from the authentication header field, specifically, Kerberosrealmtargetnameand version.
The protocol client encodes the Kerberos token, using the base64 algorithms, and sends the following request to the server. The server extracts the protocol client endpoint identity as the address-of-record in the From header field "alice contoso. The Kerberos implementation authenticates the protocol client. The server then extracts the user identity from the authentication protocol context and validates that the user is authorized to use the "alice contoso.
After the SIP registrar component completes processing, it sends back a OK response to the protocol client, which is processed by the authentication component on the server. The component locates the SA based on the reference it stored in the Via header field, or on some other mechanism, and calls into the Kerberos authentication protocol implementation to generate a signature token for the response.
Kerberos returns the signature, and the server creates an authentication information header field and sends the following message to the protocol client. The buffer that it creates for signature verification is identical to the buffer created by the server when it generated the signature. Skip to main content. Exit focus mode. Is this page helpful?

Several actions are available:. Note that you can have several regular expressions in one action. Any keyword is expanded to reflect the value actually used. External commands specified using command attribute are anything that can be executed on local host with a shell. FFmpeg adds a header to iLBC files denoting the mode that is used, either 20 or 30 ms per packet.
This header needs to be stripped from the file. The action is non-blocking. SIPp will start a light-weight thread to play the file and the scenario with continue immediately.
If needed, you will need to add a pause to wait for the end of the pcap play. You may also perform simple arithmetic add, subtract, multiply, divide on floating point values.
SIPp supports call variables that take on double-precision floating values. These variables can be assigned using one of three actions: assign, sample, or todouble. The sample action assigns values based on statistical distributions, and uses the same parameters as a statistically distributed pauses. For example, to assign the value 1. For example, the following action modifies variable one as follows:.
For example:. The value may contain any of the same substitutions that a message can contain. The result is a double value, that is less than, equal to, or greater than zero if the variable is lexographically less than, equal to, or greater than the value.
Variable testing allows you to construct loops and control structures using call variables. The lookup action is used for indexed injection files see indexed injection files. The lookup action takes a file and key as input and produces an integer line number as output. For example the following action extracts the username from an authorization header and uses it to find the corresponding line in users. Injection files, particularly when an index is defined can serve as an in-memory data store for your SIPp scenario.
The insert action takes two parameters: file and value, and the replace action takes an additional line value. For example, to inserting a new line can be accomplished as follows:. Replacing a line is similar, but a line number must be specified. You will probably want to use the lookup action to obtain the line number for use with replace as follows:.
This can be used to create rudimentary subroutines. The gettimeofday action allows you to get the current time in seconds and microseconds since the epoch.
The setdest action allows you to change the remote end point for a call. The parameters are the transport, host, and port to connect the call to.One of the most common headers is call Authorization. Wait a minute, we are talking about authentication but why the Authorization header? The distinction between authentication and authorization is important in understanding how RESTful APIs are working and why connection attempts are either accepted or denied:.
Authentication is the verification of the credentials of the connection attempt. This process consists of sending the credentials from the remote access client to the remote access server in an either plaintext or encrypted form by using an authentication protocol.
Authorization is the verification that the connection attempt is allowed. Authorization occurs after successful authentication. In other words: Authentication is stating that you are who are you are and Authorization is asking if you have access to a certain resource. I know that it is a bit confusing that in REST APIs we are using the Authorization header for doing Authentication or both but if we remember that when calling an API we are requesting an access to certain resource it means that the server should know whether it should give access to that resource or not, hence when developing and designing RESTful API Authorization header sounds just fine.
The most simple way to deal with authentication is to use HTTP basic authentication. We use a special HTTP header where we add 'username:password' encoded in base Note that even though your credentials are encoded, they are not encrypted! It is very easy to retrieve the username and password from a basic authentication. One of the downsides of basic authentication is that we need to send over the password on every request. Also, it does not safeguard against tampering of headers or body.
Another way is to use HMAC hash based message authentication. Instead of having passwords that need to be sent over, we actually send a hashed version of the password, together with more information. Let's assume we have the following credentials: username "username", password "secret".
We could add other information as well, like the current timestamp, a random number, or the md5 of the message body in order to prevent tampering of the body, or prevent replay attacks. Next, we generate a hmac:. Right now, the server knows the user "username" tries to access the resource. The server can generate the digest as well, since it has all information. Please note that the "password" is not encrypted on the server, as the server needs to know the actual value.
This is why te name "secret" is preffered and not a "password". Even if a hacker was listening in on the conversation, they could not use the authentication information to POST data to user's account details, or look at some other users accounts, or any other URL, as this would change the digest and the hacker does not have the secret that both the server and client has.
However, the hacker could access user's account whenever it wants since it doesn't change the digest. This is why many times more information is send over, like the current time, and a nonce:. We added two extra pieces of information.This chapter provides information about digest authentication setup for SIP trunks.
