Changelog Yasuo v2.3:
1) Accepts file with new-line separated list of IP addresses with “-l” switch.
2) Smart brute-forcing. Introduced app-specific credentials in the signature file, which are tried first.
3) Sqlite database integration. Yasuo output is now stored in a sqlite database.
4) All output and log files are now saved in “logs” directory.
5) And man there were bugs. Fixed now.
yasuo v2.3
yasuo 2.1
Yasuo is a ruby script that scans for vulnerable 3rd-party web applications.
While working on a network security assessment (internal, external, redteam gigs etc.), we often come across vulnerable 3rd-party web applications or web front-ends that allow us to compromise the remote server by exploiting publicly known vulnerabilities. Some of the common & favorite applications are Apache Tomcat administrative interface, JBoss jmx-console, Hudson Jenkins and so on.
If you search through Exploit-db, there are over 10,000 remotely exploitable vulnerabilities that exist in tons of web applications/front-ends and could allow an attacker to completely compromise the back-end server. These vulnerabilities range from RCE to malicious file uploads to SQL injection to RFI/LFI etc.
Yasuo is built to quickly scan the network for such vulnerable applications thus serving pwnable targets on a silver platter.
Setup / Install
gem install ruby-nmap net-http-persistent mechanize sqlite3 text-table git clone https://github.com/0xsauby/yasuo cd yasuo ./yasuo.rb update git pull origin master
Details
Yasuo provides following command-line options:
-r :: If you want Yasuo to perform port scan, use this switch to provide an IP address or IP range or an input file with new-line separated IP addresses -f :: If you do not want Yasuo to perform port scan and already have an nmap output in xml format, use this switch to feed the nmap output -n :: Tells Yasuo to not ping the host while performing the port scan. Standard nmap option. -p :: Use this switch to provide port number(s)/range -A :: Use this switch to scan all the 65535 ports. Standard nmap option. -b [all/form/basic] :: If the discovered application implements authentication, use this switch to brute-force the auth. "all" will brute-force both form & http basic auth. "form" will only brute-force form-based auth. "basic" will only brute-force http basic auth. -h :: Well, take a guess
Examples
./yasuo -r 127.0.0.1 -p 80,8080,443,8443 -b form
The above command will perform port scan against 127.0.0.1 on ports 80, 8080, 443 and 8443 and will brute-force login for all the applications that implement form-based authentication.
./yasuo -f my_nmap_output.xml -b all
The above command will parse the nmap output file “my_nmap_output.xml” and will brute-force login for all the applications that implement form-based and http basic authentication.
