Hi Jacques,
Wasn't there PHP code in the scrum application/ component to work with a
git repository?
Or was that Python?

Commit b0b02034eecf8d18ac7ea12f34469ec511269fa0 in ofbiz-framework's
branch refs/heads/trunk from Jacques Le Roux

Fixed: Remote Code Execution (File Upload) Vulnerability (OFBIZ-11948)
Lion Tree <[email protected]> has reported us that
"CVE-2020-1938 is not fully fixed".
Though it was fixed by OFBIZ-11407, it still possible for an authenticated
user
to upload a webshell included in an image using one of the upload
possibilities
in OFBiz. That is not new and covered by OFBIZ-12080 "Secure the uploads",
but
was still incomplete.
This enforces the secured uploads by
* checking in SecuredUpload::isValidImageFile that a webshell is not
embedded in
an image.
* Keeping only "<%" as a denied token for JSP webshells, instead of
currently
"<%@ page"
* Adds "application/text/x-ruby" to SecuredUpload::isExecutable
Also
* Adds "<jsp", and "<?" for PHP. Even if OFBiz does not use PHP at all,
it's often installed on servers.
* Removes "import=\"java" and "runtime.getruntime().exec(". They are no
longer useful since "<%" and "<jsp" block them.
* Remove php token since I'll put "<?" in.
* Adds "#!", rather than adding other shebangs like perl,python and ruby
This will make deniedWebShellTokens more understandable.
But I'm conscious that despite SecuredUpload::isExecutableI I still need to
better handle encoded webshells. I'll do that soon in a second approach.
I'll also certainly more prune PHP related tokens.
Thanks: Lion Tree for report

Harshit Shukla [email protected] reported this RCE vulnerability
