In this post, we present our new Burp Suite extension "TLS-Attacker".
Using this extension penetration testers and security researchers can assess the security of TLS server configurations directly from within Burp Suite.
The extension is based on the
TLS-Attacker framework and the
TLS-Scanner, both of which are developed by the Chair for Network and Data Security.
You can find the latest release of our extension at:
https://github.com/RUB-NDS/TLS-Attacker-BurpExtension/releasesTLS-Scanner
Thanks to the seamless integration of the TLS-Scanner into the BurpSuite, the penetration tester only needs to configure a single parameter: the host to be scanned. After clicking the Scan button, the extension runs the default checks and responds with a report that allows penetration testers to quickly determine potential issues in the server's TLS configuration. Basic tests check the supported cipher suites and protocol versions. In addition, several known attacks on TLS are automatically evaluated, including Bleichenbacher's attack, Padding Oracles, and Invalid Curve attacks.
Furthermore, the extension allows fine-tuning for the configuration of the underlying TLS-Scanner. The two parameters
parallelProbes and
overallThreads can be used to improve the scan performance (at the cost of increased network load and resource usage).
It is also possible to configure the granularity of the scan using
Scan Detail and
Danger Level. The level of detail contained in the returned scan report can also be controlled using the
Report Detail setting.
Please refer to the GitHub repositories linked above for further details on configuration and usage of TLS-Scanner.
Scan History
If several hosts are scanned, the Scan History tab keeps track of the preformed scans and is a useful tool when comparing the results of subsequent scans.
Additional functions will follow in later versions
Currently, we are working on integrating an at-a-glance rating mechanism to allow for easily estimating the security of a scanned host's TLS configuration.
This is a combined work of Nurullah Erinola, Nils Engelbertz, David Herring, Juraj Somorovsky, Vladislav Mladenov, and Robert Merget. The research was supported by the European Commission through the FutureTrust project (grant 700542-Future-Trust-H2020-DS-2015-1).
If you would like to learn more about TLS, Juraj and Robert will give a TLS Training at Ruhrsec on the 27th of May 2019. There are still a few seats left.More information
