ASF subversion and git services commented on OFBIZ-12080:
---------------------------------------------------------
Commit 80709b7da90ec5d43c24d4f615ec0ff51f626a83 in ofbiz-framework's branch
refs/heads/release18.12 from Jacques Le Roux
[ https://gitbox.apache.org/repos/asf?p=ofbiz-framework.git;h=80709b7 ]
Fixed: Secure the uploads (OFBIZ-12080)
Handles audio and video formats supported by Tika.
Adds few new audio and video formats in seed data.
AFAIK there are no ways to embed a webshell in an audio or video file. So I did
not sophisticate the validation, just rely on Tika.
I have also fixed bugs in SecuredUpload: in isValidSvgFile and
isValidImageIncludingSvgFile

> 2020/08/10 the OFBiz security team received a security report by Harshit
> Shukla <harshit.sh...@gmail.com>, 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.
