Note that a vulnerability does not need to actually be resolved before it is reported and that these reports can be revised as needed (reopen the issue to request changes). If you do not know how to fill certain fields, mark that in the comment and we will help you. You can delete the comments (or not). --> The Eclipse Foundation is a [Common Vulnerabilities and Exposures](https://cve.mitre.org/) (CVE) Numbering Authority. Creating this ticket initiates **reservation** of a CVE ID for the documented vulnerability. The reserved CVE ID will be posted in a comment below, and kept **confidential** until explicit publication request. > [!note] > To request CVE *publication*, please open a [CVE publication](https://gitlab.eclipse.org/security/cve-assignment/-/issues/new?issuable_template=CVE%20Publication%20Request&issue[confidential]=true) ticket. Please fill in the fields below to draft the CVE record. --- <!-- Required. Specify the project's name (e.g., "Eclipse Dash") and Eclipse Foundation ID, e.g., "technology.dash". --> ## CVE record information **Project name:** Eclipse Ditto (component: Ditto Explorer UI, `ui/` in https://github.com/eclipse-ditto/ditto, incl. the hosted instance at https://eclipse-ditto.github.io/ditto/) **Project id:** iot.ditto <!-- Required (for publication). Specify the version range as precisely as possible, e.g., "[3.0, 3.5.1]" or "[3.0, 3.5.1)". Note that using the standard range notion, square brackets are inclusive (i.e., that version is included in the range), and round brakets are exclusive (the vulnerability affects all versions up to but not including the named version). Multiple ranges can be provided. --> **Versions affected:** [3.6.0, 3.9.7] (no fixed version yet; the range will be updated to the form "[3.6.0, <fix version>)" once a fix is released) <!-- Required (for publication). The Common Weakness Enumeration (CWE) code comes from here: https://cwe.mitre.org/, e.g., "CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection')". Multiple codes can be provided. --> **Common Weakness Enumeration (CWE):** - [CWE-15: External Control of System or Configuration Setting](https://cwe.mitre.org/data/definitions/15.html) - [CWE-346: Origin Validation Error](https://cwe.mitre.org/data/definitions/346.html) - [CWE-522: Insufficiently Protected Credentials](https://cwe.mitre.org/data/definitions/522.html) <!-- Optional. The Common Attack Pattern Enumerations and Classifications (CAPEC) code comes from here: https://capec.mitre.org/, e.g., "CAPEC-63: Cross-Site Scripting (XSS)".

Provide a Common Vulnerability Scoring System (CVSS). Note that if you do not provide this, then some agencies (e.g. NIST) will compute it on the project's behalf. Please be sure to include the CVSS version number, e.g., "CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H". There's help here: https://www.first.org/cvss/calculator/4.0 --> **Common Vulnerability Scoring System:** [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:L/VA:N/SC:H/SI:H/SA:N](https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:L/VA:N/SC:H/SI:H/SA:N) (7.1 High) <!-- Required (for publication). The summary should start with the name of the project, e.g., "Eclipse Vert.x", then a description of the affected versions, followed by a description of the problem. The summary should be concise. For example, "In Eclipse Vert.x version 3.0 to 3.5.1, the HttpServer response headers and HttpClient request headers do not filter carriage return and line feed characters from the header value. This allow unfiltered values to inject a new header in the client request or server response." --> **Summary:** In Eclipse Ditto versions 3.6.0 to 3.9.7, the Ditto Explorer UI loads its complete environment configuration, including the Ditto API URI and the OpenID Connect (OIDC) provider settings, from an arbitrary cross-origin URL supplied in the `environmentsURL` query parameter. It adopts this configuration without user confirmation and persists it in the browser's localStorage. A crafted link can therefore set an attacker-controlled OIDC `authority` with `autoSso` enabled. The UI then automatically starts a login at the genuine identity provider but exchanges the returned authorization code together with its PKCE `code_verifier` at an attacker-controlled token endpoint. This lets the attacker redeem the code for the victim's access and refresh tokens. Alternatively, an attacker-controlled `api_uri` causes the UI to send the victim's bearer token or Basic credentials to the attacker. Because the configuration is persisted, later visits to the UI without the crafted link repeat the token theft. <!-- Required (for publication). Include a link to the issue (e.g., GitHub Security Advisory) that's being used to track/resolve the issue. Other links that provide more information can be provided. For example, you may later publish the link to the fix commit. --> **Links:** - GitHub Security Advisory: https://github.com/eclipse-ditto/ditto/security/advisories/GHSA-8767-g5qv-9jcf - Vulnerability report: https://gitlab.eclipse.org/security/vulnerability-reports/-/work_items/1207 <!-- Optional.
