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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3590 advisory.

    Package        : python-reportlab     Version        : 3.5.13-1+deb10u2     CVE ID         : CVE-2019-19450 CVE-2020-28463

    Security issues were discovered in python-reportlab, a Python library     for generating PDFs and graphics, which could lead to remote code     execution or authorization bypass.

    CVE-2019-19450

        Ravi Prakash Giri discovered a remote code execution vulnerability         via crafted XML document where <unichar code= is followed by         arbitrary Python code.

        This issue is similar to CVE-2019-17626.

    CVE-2020-28463

        Karan Bamal discovered a Server-side Request Forgery (SSRF)         vulnerability via <img> tags.  New settings trustedSchemes and         trustedHosts have been added as part of the fix/mitigation: they         can be used to specify an explicit allowlist for remote sources.

    For Debian 10 buster, these problems have been fixed in version     3.5.13-1+deb10u2.

    We recommend that you upgrade your python-reportlab packages.
