Release 2.6.0

This release contains a large number of changes, in particular to the ZAP API. We have added a significant number of new API endpoints, working towards our goal of making ZAP completely controllable via the API. We have also changed some of the existing endpoints and in all cases these changes are backwards compatible.

The full release also includes a new JxBrowser add-on as well as platform specific webdrivers to make it even easier to interact with ZAP through a wide variety of browsers.

API Security Changes

We have changed the API security in response to issues reported to us via our bug bounty program. Details of the vulnerabilities are given below. The security changes are by necessity not backwards compatible, although we have include options for disabling them if you use ZAP in a safe environment.

By default all API calls now require either the API key or a nonce. These can be supplied via URL parameters, POST parameters or headers. The supported ZAP API clients (including Java and Python) have been updated to supply the API key via a header. Nonces are generated by ZAP and are intended to be used by ZAP add-ons that need to access the ZAP API. For full details see the Options API screen.

There are a set of new API options related to security:

  • UI Enabled - If enabled then the API Web UI is available to all machines that are able to use ZAP as a proxy. This is enabled by default.
  • IP addresses permitted to use the API - By default only the machine ZAP is running on is able to access the ZAP API. You can allow other machines access to the API by adding suitable regex patterns. You should only add IP addresses that you trust.
  • Do not require an API key for safe operations - If enabled then the API key is not required for Views or Other operations that are considered 'safe', in other words operations that do not make any changes to ZAP. Such operations do however give access to ZAP data such as alert, messages, and file system paths. They can also be used by web applications to detect the presence of ZAP.
  • Report permission errors via API - If enabled then ZAP will report permission errors via the API, which can be used by web applications to detect the presence of ZAP. This is not a serious problem in a safe environment but if you are using ZAP against potentially malicious sites then you should not enable it.

All ZAP options can be specified via the command line when you start ZAP - see the API Key FAQ for full details. We have also added even more security headers to the API including a strong Content Security Policy.

Vulnerability Details

The following vulnerabilities have been reported in previous versions of ZAP. Other less serious issues have been also been fixed as a matter of course. Many thanks to all of the researchers who have ethically reported these issues to us via our bug bounty program. If you need more details about any of these vulnerabilities then please contact us.

RCE via Anti CSRF Test Form and API Key Disclosure

If the user used the Anti CSRF Test Form against a specifically crafted HTML page then the API key was leaked to that site. The site could then access the ZAP API and perform any action, including uploading ZAP scripts. Scripts can only be uploaded from ‘local’ filesystems but if the user is running ZAP on Windows then the attacker can make a malicious script available via a public SMB share. This appears to ZAP to be a local file and the script is therefore uploaded and can be run via the API. The requirement for the API key or nonce on all API operations are a direct result of this vulnerability, as are changing add-ons to use nonces to reduce the risk of leaking the API key.

Windows Installer Vulnerable to DLL Hijacking

The ZAP Windows Installer for all versions up to and including 2.5.0 are vulnerable to DLL Hijacking on Windows 7 (and earlier versions). This is a vulnerability in the in 3rd party installer InnoSetup. The 2.6.0 Installers (on all platforms) are now generated using Install4J.

If for some reason you do need to install previous versions of ZAP on Windows 7 or earlier then we recommend that you move the installer to a clean directory before running it.

Note that Burp Suite also use Install4J so future vulnerabilities in Install4j-generated installers may be eligible for the Burp Suite bug bounty program: https://hackerone.com/portswigger

Arbitrary Code Execution via Invoke Applications Parameter Injection

HTML parameters could be specifically crafted to cause arbitrary code execution, if the user choose to invoke the targeted application with a request containing that parameter from within ZAP. The Invoke Applications add-on has been updated to fix this issue - all ZAP users should install this new version before continuing to use the add-on.

XSS via Anti CSRF Test Form

The Anti CSRF Test Form was vulnerable to XSS attacks if run against a specifically crafted HTML page. The API now uses a strong Content Security Policy to prevent such issues

API Vulnerable to DNS Rebinding

The API was vulnerable to DNS Rebinding attacks. It now checks the host header and rejects any requests from unexpected hosts.
