Vulnerable Application
Affecting total.js package, versions:
- >=2.1.0 <2.1.1
- >=2.2.0 <2.2.1
- >=2.3.0 <2.3.1
- >=2.4.0 <2.4.1
- >=2.5.0 <2.5.1
- >=2.6.0 <2.6.3

- >=3.0.0 <3.0.1
- >=3.1.0 <3.1.1
- >=3.2.0 <3.2.4
Verification Steps
- On a Node v8 environment do:
npm install [email protected] - Install an app on top of the Total.js framework, something like Total.js CMS
git clone https://github.com/totaljs/cms.gitcd cms && npm install
- Start
msfconsole use auxiliary/scanner/http/totaljs_traversalset RHOST <IP>set RPORT <PORT>run- Verify you get Total.js version if the target is vulnerable!
Options
DEPTH
Traversal depth. Default is 1
FILE
File to obtain. Default is databases/settings.json
