TencentOS Server 4: grafana (TSSA-2025:0339)

critical Nessus Plugin ID 276350

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0339 advisory.

 Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

 CVE-2024-8986:
 A vulnerability was found in Grafana's data source proxy API, which allows authorization checks to be bypassed by adding an extra slash character in the URL path. Users with minimal permissions could gain unauthorized read access to GET endpoints in Alert manager and Prometheus data sources. The issue primarily affects data sources that implement route-specific permissions, including Alert manager and certain Prometheus-based data sources.

 CVE-2024-8118:
 The tokenizer incorrectly interprets tags with unquoted attribute values that end with a solidus character (/) as self-closing. When directly using Tokenizer, this can result in such tags incorrectly being marked as self-closing, and when using the Parse functions, this can result in content following such tags as being placed in the wrong scope during DOM construction, but only when tags are in foreign content (e.g.
 <math>, <svg>, etc contexts).

 CVE-2024-11741:
 The grafana plugin SDK bundles build metadata into the binaries it compiles; this metadata includes the repository URI for the plugin being built, as retrieved by running `git remote get-url origin`.

 If credentials are included in the repository URI (for instance, to allow for fetching of private dependencies), the final binary will contain the full URI, including said credentials.

 CVE-2025-22872:
 In Grafana, the wrong permission is applied to the alert rule write API endpoint, allowing users with permission to write external alert instances to also write alert rules.

 CVE-2025-3454:
 Grafana is an open-source platform for monitoring and observability.
 The Grafana Alerting VictorOps integration was not properly protected and could be exposed to users with Viewer permission.
 Fixed in versions 11.5.0, 11.4.1, 11.3.3, 11.2.6, 11.1.11, 11.0.11 and 10.4.15

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
