Jacques Le Roux updated OFBIZ-12080:
------------------------------------
Description:
2020/08/10 the OFBiz security team received a security report by Harshit Shukla
<[email protected]>, roughly it was (quoting part of it to simplify):
bq. I have identified a Remote Code Execution (RCE) Vulnerability. The reason
behind this RCE is lack of file extension check at
catalog/control/UploadCategoryImage?productCategoryId=CATALOG1_BEST_SELL&pload_file_type=category
Using this post-auth RCE in OFBiz demos, Harshit was able to get some AWS
credentials by uploading a webshell (based on [0]). By security, it was then
decided by the Infra and OFBiz security teams to shut down the demos.
After I decided we needed to secure all our uploads and not only checking
extensions, I began to work on the vulnerablity. During this work I discovered,
according to [1] and [2], that these AWS credentials are so far considered
harmless.
This post-auth RCE relies on the demo data. In our documentation[3], we warn
our users to not use the demo data. Notably because they allow to sign in as an
admin!
After discussing these elements with Mark J Cox (VP of ASF security team[4]) we
in common decided that no CVE was necessary.
