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 BaSyx Helm Charts **Project id:** dt.basyx <!-- 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:** `aas-basyx-v2-full` chart [2.2.0, 2.2.0] when the bundled Keycloak is enabled (`keycloak.enabled=true`). No fixed version of the `aas-basyx-v2-full` chart exists. <!-- 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-312: Cleartext Storage of Sensitive Information](https://cwe.mitre.org/data/definitions/312.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)". Multiple codes can be provided. --> **Common Attack Pattern Enumerations and Classifications (CAPEC):** - [CAPEC-37: Retrieve Embedded Sensitive Data](https://capec.mitre.org/data/definitions/37.html) <!-- Optional. 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:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H (7.5) <!-- 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 BaSyx Helm Charts version 2.2.0 of the `aas-basyx-v2-full` chart, deployments with the bundled Keycloak enabled store the client secret of the `basyx-technical-user` OAuth2 client in cleartext in a Kubernetes ConfigMap. This client uses the client-credentials grant and its service account holds the realm `admin` role. The chart correctly writes `keycloak.technicalUser.clientSecret` to a Kubernetes Secret, but the template `basyx-keycloak-realm.yaml` also substitutes the same value into the Keycloak realm-import JSON, which is stored in the ConfigMap `<keycloak.fullnameOverride>-realm`. A principal that can read ConfigMaps but not Secrets in the release namespace, such as a holder of the built-in Kubernetes `view` ClusterRole, can read the client secret from the ConfigMap. They can then exchange it at the Keycloak token endpoint for an access token with the `admin` role. That token grants full create, read, update, delete and execute rights on all BaSyx repositories and registries in the deployment. The bundled Keycloak is disabled by default. No fixed release of the `aas-basyx-v2-full` chart exists. Affected users should migrate to the `basyx` chart, or deploy without the bundled Keycloak and rotate the `basyx-technical-user` client secret. <!-- Required (for publication).
