MS17-010 executable exploit for local/remote privilege escalation

Hi there, Few months ago I modified a version of the Worawit Wang: GitHub zzz_exploit for MS17-010. The new version implements a few options such as username/password specification and an arbitrary command to be executed. It does not change anything related to the SMB exploitation This is a bundle with an executable and dependencies and DOES NOT require any python install. This is very suitable for scenarios where one has low privilege access to a vulnerable Windows but does not have any Python available nor Metasploit for proper exploitation. I hope you enjoy it. Here it goes: MS17-010 exploit .

Various SSRF conditions on KeyCDN tools

Hi There, It is common to find websites/tools on the internet which performs speed test, loading third party images, load external JavaScript files etc. to be vulnerable to Server Side Request Forgery. I've found a couple of them, reported but some of them did not take it seriously. I've recently ran into KeyCDN tools website , a site owned and operated by KeyCDN , a CDN company and reported to be one of the best solution according to the TechRadar info . After looking at some functionalities presented on the web site I've found a few SSRF conditions. Here it goes: 1) Using the Trace Route utility to discovery some Internal IP Address When I used the Trace Route functionality there was an internal IP address 10.0.10.1 (which seems  no longer there) belonging to the Frankfurt POP. 2) Using the Ping utility to confirm the above finding (and maybe Brute Force some hosts?) I will discuss the FQDN you are seeing there soon! 3) Using the Performance Test  ...

Make-HtDigest - a tool to audit password files for WildFly / JBOSS / Apache

Hi there, I've created a tool called Make-HtDigest which is able to generate username + password combination based on a word-list for HTTP Digest Authentication. This can be used to compare output with real password files such as mgmt-users.properties from WildFly and .digest_pw from Apache. I hope it is useful and you enjoy it.

A tool to detect Slow HTTP DoS attacks on pcap files

Image
Hello everybody, I wrote a python tool to detect Slow HTTP DoS attacks on pcap files: slowdos_detector . This is ideal for post-mortem analysis on captured traffic (pcap files). If you are curious about how to test it, you could leverage slowhttptest  to launch an HTTP DoS attack on your test server, capture the traffic and then use slowdos_detector to show offending HTTP transactions. Enjoy it and ping me if you have questions, issues or suggestions.

Cross-site Scripting (XSS) on Goodreads.com

Recently on an independent research I've found the Goodreads API was vulnerable to a Reflected Cross-site scripting . The issue happens on their REST API on a callback function parameter. No sanitizing mechanism was found and the parameter is echoed back in the JSON payload, allowing a malicious user to potentially launch XSS attacks. I've submitted the issue to the Goodreads' security team and this was quickly fixed. Goodreads is an Amazon company with  55 millions of users. Their site is ranked 139 in the USA and 336 globally, according to Alexa .
