CVE-2024-47605 WRITEUP MEDIUM WRITEUP
Silverstripe asset-admin < 5.3.8 - oEmbed Cross-Site Scripting
silverstripe-asset-admin is a silverstripe assets gallery for asset management.

The HTML is not sanitized before replacing the shortcode, allowing a script payload to be executed on both the CMS and the front-end of the website. This issue has been addressed in silverstripe/framework version 5.3.8 and users are advised to upgrade. There are no known workarounds for this vulnerability.

Users should upgrade to Silverstripe Framework 4.12.15 or above to address the issue.
CVSS 5.4
CVE-2023-40180 WRITEUP HIGH WRITEUP
silverstripe/graphql 3.0.0-3.8.1 - Unauthenticated Denial of Service via Recursive GraphQL Query
silverstripe-graphql is a package which serves Silverstripe data in GraphQL representations. An attacker could use a recursive graphql query to execute a Distributed Denial of Service attack (DDOS attack) against a website. This mostly affects websites with publicly exposed graphql schemas. If your Silverstripe CMS project does not expose a public facing graphql schema, a user account is required to trigger the DDOS attack. If your site is hosted behind a content delivery network (CDN), such as Imperva or CloudFlare, this may further mitigate the risk. This issue has been addressed in versions 3.8.2, 4.1.3, 4.2.5, 4.3.4, and 5.0.3. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVSS 7.5
CVE-2024-29885 WRITEUP MEDIUM WRITEUP
Silverstripe Reports <5.2.3 - Info Disclosure
silverstripe/reports is an API for creating backend reports in the Silverstripe Framework. In affected versions reports can be accessed by their direct URL by any user who has access to view the reports admin section, even if the `canView()` method for that report returns `false`. This issue has been addressed in version 5.2.3. All users are advised to upgrade. There are no known workarounds for this vulnerability.
CVSS 4.3
CVE-2024-32981 WRITEUP MEDIUM WRITEUP
Silverstripe framework < 5.2.16 - Stored Cross-Site Scripting via Crafted Encoded Payload
Silverstripe framework is the PHP framework forming the base for the Silverstripe CMS. In affected versions a bad actor with access to edit content in the CMS could add send a specifically crafted encoded payload to the server, which could be used to inject a JavaScript payload on the front end of the site. The payload would be sanitised on the client-side, but server-side sanitisation doesn't catch it. The server-side sanitisation logic has been updated to sanitise against this type of attack in version 5.2.16. All users are advised to upgrade. There are no known workarounds for this vulnerability.
CVSS 5.4
CVE-2024-53277 WRITEUP MEDIUM WRITEUP
Silverstripe Framework < 5.3.8 - Cross-Site Scripting in Form Message Content
Silverstripe Framework is a PHP framework which powers the Silverstripe CMS. In some cases, form messages can contain HTML markup. This is an intentional feature, allowing links and other relevant HTML markup for the given message. Some form messages include content that the user can provide. There are scenarios in the CMS where that content doesn't get correctly sanitised prior to being included in the form message, resulting in an XSS vulnerability. This issue has been addressed in silverstripe/framework version 5.3.8 and users are advised to upgrade. There are no known workarounds for this vulnerability.
