A flaw was found in Django REST Framework versions before 3.12.0 and before 3.11.2. When using the browseable API viewer, Django REST Framework fails to properly escape certain strings that can come from user input. This allows a user who can control those strings to inject malicious <script> tags, leading to a cross-site-scripting (XSS) vulnerability.

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 a vulnerability as referenced in the dsa-5186 advisory.

    Two cross-site scripting vulnerabilities were discovered in the Django Rest Framework, a toolkit to build     web APIs. For the oldstable distribution (buster), this problem has been fixed in version 3.9.0-1+deb10u1.
    The stable distribution (bullseye) is not affected. We recommend that you upgrade your djangorestframework     packages. For the detailed security status of djangorestframework please refer to its security tracker     page at: https://security-tracker.debian.org/tracker/djangorestframework

Tenable has extracted the preceding description block directly from the Debian security advisory.

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