Vulnerabilities

The Open edx Enterprise Service app provides enterprise features to the Open edX platform. From 7.0.2 to 7.0.4, the sync_provider_data endpoint in SAMLProviderDataViewSet fetches SAML metadata from a URL stored in SAMLProviderConfig.metadata_source. An authenticated user with the Enterprise Admin role can set this field to an arbitrary URL via the SAMLProviderConfigViewSet PATCH endpoint, then trigger a server-side HTTP request by calling sync_provider_data. The fetch in fetch_metadata_xml() passes the URL directly to requests.get() with no scheme enforcement, IP filtering, or timeout. This vulnerability is fixed in 7.0.5.

Open edX Platform enables the authoring and delivery of online learning at any scale. The sync_provider_data endpoint in SAMLProviderDataViewSet allows authenticated Enterprise Admin users to supply an arbitrary URL via the metadata_url POST parameter. This URL is passed directly to requests.get() in fetch_metadata_xml() without any URL validation, IP filtering, or scheme enforcement. An attacker with Enterprise Admin privileges can force the server to make HTTP requests to internal network services, cloud metadata endpoints (e.g., AWS 169.254.169.254), or other attacker-controlled destinations. This vulnerability is fixed by commit 6fda1f120ff5a590d120ae1180185525f399c6d0 and 70a56246dd9c9df57c596e64bdd8a11b1d9da054.

Open edX Platform enables the authoring and delivery of online learning at any scale. The view_survey endpoint accepts a redirect_url GET parameter that is passed directly to HttpResponseRedirect() without any URL validation. When a non-existent survey name is provided, the server issues an immediate HTTP 302 redirect to the attacker-controlled URL. Additionally, the same unvalidated URL is embedded in a hidden form field and returned in a JSON response after form submission, where client-side JavaScript performs location.href = url. This enables phishing and credential theft attacks against authenticated Open edX users. This vulnerability is fixed with commit 76462f1e5fa9b37d2621ad7ad19514b403908970.

This openedx-translations repository contains translation files from Open edX repositories to be kept in sync with Transifex. Before moving to pulling translations from the openedx-translations repository via openedx-atlas, translations in the edx-platform repository were validated using edx-i18n-tools. This validation included protection against malformed translations and translations-based script injections. Prior to this patch, the validation implemented in the openedx-translations repository did not include the same protections. The maintainer inspected the translations in the edx-platform directory of both the main and open-release/redwood.master branches of the openedx-translations repository and found no evidence of exploited translation strings.

Open edX Platform is a service-oriented platform for authoring and delivering online learning. A user with a JWT and more limited scopes could call endpoints exceeding their access. This vulnerability has been patched in commit 019888f.

The Quick Post Duplicator for WordPress is vulnerable to SQL Injection via the ‘post_id’ parameter in versions up to, and including, 2.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers with contributor-level privileges to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

LTI Consumer XBlock implements the consumer side of the LTI specification enabling integration of third-party LTI provider tools. Versions 7.0.0 and above, prior to 7.2.2, are vulnerable to Missing Authorization. Any LTI tool that is integrated with on the Open edX platform can post a grade back for any LTI XBlock so long as it knows or can guess the block location for that XBlock. An LTI tool submits scores to the edX platform for line items. The code that uploads that score to the LMS grade tables determines which XBlock to upload the grades for by reading the resource_link_id field of the associated line item. The LTI tool may submit any value for the resource_link_id field, allowing a malicious LTI tool to submit scores for any LTI XBlock on the platform. The impact is a loss of integrity for LTI XBlock grades. This issue is patched in 7.2.2. No workarounds exist.

Drag and Drop XBlock v2 implements a drag-and-drop style problem, where a learner has to drag items to zones on a target image. Versions prior to 3.0.0 are vulnerable to cross-site scripting in multiple XBlock Fields. Any platform that has deployed the XBlock may be impacted. Version 3.0.0 contains a patch for this issue. There are no known workarounds.

Open edX platform before 2022-06-06 allows XSS via the "next" parameter in the logout URL.

CycloneDX BOM Repository Server is a bill of materials (BOM) repository server for distributing CycloneDX BOMs. CycloneDX BOM Repository Server before version 2.0.1 has an improper input validation vulnerability leading to path traversal. A malicious user may potentially exploit this vulnerability to create arbitrary directories or a denial of service by deleting arbitrary directories. The vulnerability is resolved in version 2.0.1. The vulnerability is not exploitable with the default configuration with the post and delete methods disabled. This can be configured by modifying the `appsettings.json` file, or alternatively, setting the environment variables `ALLOWEDMETHODS__POST` and `ALLOWEDMETHODS__DELETE` to `false`.

Open edX through Lilac.1 allows XSS in common/static/common/js/discussion/utils.js via crafted LaTeX content within a discussion.

Studio in Open edX Ironwood 2.5, when CodeJail is not used, allows a user to go to the "Create New course>New section>New subsection>New unit>Add new component>Problem button>Advanced tab>Custom Python evaluated code" screen, edit the problem, and execute Python code. This leads to arbitrary code execution.

Open edX Ironwood.1 allows support/certificates?user= reflected XSS.

Open edX Ironwood.1 allows support/certificates?course_id= reflected XSS.

Recommender before 2018-07-18 allows XSS.

edx-platform before 2017-08-03 allows attackers to trigger password-reset e-mail messages in which the reset link has an attacker-controlled domain name.

edx-platform before 2016-06-06 allows CSRF.
