• CVE-2022-38462 Reflected XSS in querystring parameters

  Severity:

  Medium (?)

  Identifier:

  CVE-2022-38462

  Versions Affected:

  silverstripe/framework: ^3.0.0, ^4.0.0

  Versions Fixed:

  silverstripe/framework: 4.11.13

  Release Date:

  2022-11-21

  An attacker could inject a XSS payload in a Silverstripe CMS response by carefully crafting a return URL on a /dev/build or /Security/login request.

  To exploit this vulnerability, an attacker would need to convince a user to follow a link with a malicious payload.

  This will only affect projects configured to output PHP warnings to the browser. By default, Silverstripe CMS will only output PHP warnings if your SS_ENVIRONMENT_TYPE environment variable is set to dev. Production sites should always set SS_ENVIRONMENT_TYPE to live.

  Read the Environment management documentation for more details on configuring environment variables.

  Most projects should be able to apply the patch without further work. There's no legitimate use case for this behaviour.

  Regression testing should focus on areas where the location header is used to redirect users.

  Base CVSS: 4.2

• CVE-2022-38148 Blind SQL Injection via GridFieldSortableHeader

  Severity:

  High (?)

  Identifier:

  CVE-2022-38148

  Versions Affected:

  silverstripe/framework: ^3.0.0, ^4.0.0

  Versions Fixed:

  silverstripe/framework: 4.10.11, 4.11.14

  Release Date:

  2022-11-21

  Gridfield state is vulnerable to SQL injections. The vast majority of Gridfields in Silverstripe CMS are affected by this vulnerability.

  An attacker with CMS access could execute an arbitrary SQL statement by adding an SQL payload in some parts of the GridField state.

  Most projects should be able to apply the patch without further work. There's no legitimate use case for this behaviour.

  Regression testing should focus on custom filtering and sorting logic for Gridfields.

  Base CVSS: 7.1

  Reported by: TF1T via huntr.dev

• CVE-2022-38147 XSS via uploaded gpx file

  Severity:

  Medium (?)

  Identifier:

  CVE-2022-38147

  Versions Affected:

  silverstripe/assets: ^1.0.0

  Versions Fixed:

  silverstripe/assets: 1.11.1

  Release Date:

  2022-11-21

  A malicious content author could upload a GPX file with a Javascript payload. The payload could then be executed by luring a legitimate user to view the file in a browser with support for GPX files. GPX is an XML-based format used to store GPS data.

  By default, Silverstripe CMS will no longer allow GPX files to be uploaded to the assets area.

  Most projects should be able to apply the patch without further work. While there can be a legitimate use case for using GPX files, it's an uncommon one. You can re-enable support for GPX files if you have a need for them, but beware there's an inherent risk in allowing content authors to upload this kind of file.

  Regression testing should focus on identifying if your site makes use of any GPX files. You can validate if you have any pre-existing GPX file on your Silverstripe CMS site by accessing the Files area and searching for "GPX". You'll want to delete any GPX file prior to applying the patch.

  Base CVSS: 4.6

• CVE-2022-38146 URL XSS vulnerability due to outdated jquery in CMS

  Severity:

  Medium (?)

  Identifier:

  CVE-2022-38146

  Versions Affected:

  silverstripe/admin: ^1.0.0

  Versions Fixed:

  silverstripe/admin: ^1.11.3

  Release Date:

  2022-11-21

  The Silverstripe CMS UI uses jQuery 1.7.2. This version of jQuery is affected by CVE-2019-11358 Object.prototype pollution. An attacker could perform an XSS attack by convincing a user to follow a link with a specially crafted __proto__ query string parameter.

  silverstripe/admin 1.11.3 addresses this problem by stopping all JavaScript execution if a __proto__ query string is present in the URL. This fix is just a stopped gap measure.

  This issue will be properly remediated by upgrading to jQuery 3.6.1 or later in the Silverstripe CMS 4.12.0 release.

  Most projects should be able to apply the patch without further work. There's no legitimate use case for this behaviour.

  Regression testing should focus on custom CMS UI functionality that might be implemented in your project.

  If you use the jQuery version distributed with Silverstripe CMS in the front end of your site, you may be affected by this vulnerability via the front end. If this applies to youp project, you should upgrade your theme to use a more recent jQuery version.

• CVE-2022-38145 Stored XSS in Compare Mode

  Severity:

  Medium (?)

  Identifier:

  CVE-2022-38145

  Versions Affected:

  silverstripe/versioned-admin: ^1.0.0

  Versions Fixed:

  silverstripe/versioned-admin: ^1.11.1

  Release Date:

  2022-11-21

  A malicious content author could add a Javascript payload to a page's meta description and get it executed in the versioned history compare view.

  This vulnerability requires access to the CMS to be deployed. The attacker must then convince a privileged user to access the version history for that page.

  Most projects should be able to apply the patch without further work. There's no legitimate use case for this behaviour.

  Regression testing should focus on version comparison with the page history tab.

  Base CVSS: 4.6

  Reported by: TF1T via huntr.dev

• CVE-2022-37430 Stored XSS using uppercase characters in HTMLEditor

  Severity:

  Medium (?)

  Identifier:

  CVE-2022-37430

  Versions Affected:

  silverstripe/framework: ^3.0.0, ^4.0.0

  Versions Fixed:

  silverstripe/framework: 4.11.13

  Release Date:

  2022-11-21

  A malicious content author could add a Javascript payload to the href attribute of a link. A similar issue was identified and fixed via CVE-2022-28803. However, the fix didn't account for the casing of the href attribute.
  An attacker must have access to the CMS to exploit this issue.

  Most projects should be able to apply the patch without further work. There's no legitimate use case for this behaviour.

  Regression testing should focus on link creations within HTML editor fields.

  Base CVSS: 4.6

• CVE-2022-37429 Stored XSS using HTMLEditor

  Severity:

  Medium (?)

  Identifier:

  CVE-2022-37429

  Versions Affected:

  silverstripe/framework: ^4.0.0, ^3.0.0

  Versions Fixed:

  silverstripe/framework: 4.11.13

  Release Date:

  2022-11-21

  A malicious content author could add a JavaScript payload to the href attribute of a link by splitting a javascript URL with white space characters.

  An attacker must have access to the CMS to exploit this issue.

  Most projects should be able to apply the patch without further work. There's no legitimate use case for this behaviour.

  Regression testing should focus on link creations within HTML editor fields.

  Base CVSS: 4.6

  Reported by: TF1T via huntr.dev

• CVE-2022-37421 Stored XSS in custom meta tags

  Severity:

  Low (?)

  Identifier:

  CVE-2022-37421

  Versions Affected:

  silverstripe/cms: ^4.0.0, ^3.0.0

  Versions Fixed:

  silverstripe/cms: 4.11.3

  Release Date:

  2022-11-21

  A malicious content author could create a custom meta tag and execute an arbitrary JavaScript payload. This would require convincing a legitimate user to access a page and enter a custom keyboard shortcut.
  This requires CMS access to exploit.

  Most projects should be able to apply the patch without further work. There's no legitimate use case for this behaviour.

  Regression testing should focus on pages with pre-existing custom meta tags, if any are present.

  Base CVSS: 3.7

• CVE-2022-29254 Failed payment recorded has completed

  Severity:

  Low (?)

  Identifier:

  CVE-2022-29254

  Versions Affected:

  silverstripe/silverstripe-omnipay: <=2.5.1, <=3.0.1, <=3.1.3, <=3.2.0

  Versions Fixed:

  silverstripe/silverstripe-omnipay: 2.5.2, 3.0.2, 3.1.4, 3.2.1

  Release Date:

  2022-06-06

  For a subset of Omnipay gateways (those that use intermediary states like isNotification() or isRedirect()), if the payment identifier or success URL is exposed it is possible for payments to be prematurely marked as completed without payment being taken. This is mitigated by the fact that most payment gateways hide this information from users, however some issuing banks offer flawed 3DSecure implementations that may inadvertently expose this data.

• CVE-2021-36150 - Insert from files link text - Reflective (self) Cross Site Scripting

  Severity:
