medium Nessus Plugin ID 153614

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED12 / SLES12 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2021:3209-1 advisory.

 - All versions of package reportlab are vulnerable to Server-side Request Forgery (SSRF) via img tags. In order to reduce risk, use trustedSchemes & trustedHosts (see in Reportlab's documentation) Steps to reproduce by Karan Bamal: 1. Download and install the latest package of reportlab 2. Go to demos -> odyssey -> dodyssey 3. In the text file odyssey.txt that needs to be converted to pdf inject <img src=http://127.0.0.1:5000 valign=top/> 4. Create a nc listener nc -lp 5000 5. Run python3 dodyssey.py 6. You will get a hit on your nc showing we have successfully proceded to send a server side request 7.
 dodyssey.py will show error since there is no img file on the url, but we are able to do SSRF (CVE-2020-28463)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected python-reportlab package.
