Grafana is an open-source platform for monitoring and observability. Starting with the 9.1 branch, Grafana introduced the ability to search for a JWT in the URL query parameter auth_token and use it as the authentication token. By enabling the "url_login" configuration option (disabled by default), a JWT might be sent to data sources. If an attacker has access to the data source, the leaked token could be used to authenticate to Grafana.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:2575-1 advisory.

  - All versions of package trim are vulnerable to Regular Expression Denial of Service (ReDoS) via trim().
    (CVE-2020-7753)

  - ansi-regex is vulnerable to Inefficient Regular Expression Complexity (CVE-2021-3807)

  - json-schema is vulnerable to Improperly Controlled Modification of Object Prototype Attributes ('Prototype     Pollution') (CVE-2021-3918)

  - In Async before 2.6.4 and 3.x before 3.2.2, a malicious user can obtain privileges via the mapValues()     method, aka lib/internal/iterator.js createObjectIterator prototype pollution. (CVE-2021-43138)

  - follow-redirects is vulnerable to Exposure of Private Personal Information to an Unauthorized Actor     (CVE-2022-0155)

  - In net/http in Go before 1.18.6 and 1.19.x before 1.19.1, attackers can cause a denial of service because     an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error. (CVE-2022-27664)

  - Grafana is an open-source platform for monitoring and observability. Versions on the 8.x and 9.x branch     prior to 9.0.3, 8.5.9, 8.4.10, and 8.3.10 are vulnerable to stored cross-site scripting via the Unified     Alerting feature of Grafana. An attacker can exploit this vulnerability to escalate privilege from editor     to admin by tricking an authenticated admin to click on a link. Versions 9.0.3, 8.5.9, 8.4.10, and 8.3.10     contain a patch. As a workaround, it is possible to disable alerting or use legacy alerting.
    (CVE-2022-31097)

  - Grafana is an open-source platform for monitoring and observability. In versions 5.3 until 9.0.3, 8.5.9,     8.4.10, and 8.3.10, it is possible for a malicious user who has authorization to log into a Grafana     instance via a configured OAuth IdP which provides a login name to take over the account of another user     in that Grafana instance. This can occur when the malicious user is authorized to log in to Grafana via     OAuth, the malicious user's external user id is not already associated with an account in Grafana, the     malicious user's email address is not already associated with an account in Grafana, and the malicious     user knows the Grafana username of the target user. If these conditions are met, the malicious user can     set their username in the OAuth provider to that of the target user, then go through the OAuth flow to log     in to Grafana. Due to the way that external and internal user accounts are linked together during login,     if the conditions above are all met then the malicious user will be able to log in to the target user's     Grafana account. Versions 9.0.3, 8.5.9, 8.4.10, and 8.3.10 contain a patch for this issue. As a     workaround, concerned users can disable OAuth login to their Grafana instance, or ensure that all users     authorized to log in via OAuth have a corresponding user account in Grafana linked to their email address.
    (CVE-2022-31107)

  - An attacker may cause a denial of service by crafting an Accept-Language header which ParseAcceptLanguage     will take significant time to parse. (CVE-2022-32149)

  - Grafana is an open-source platform for monitoring and observability. Versions prior to 9.1.6 and 8.5.13     are vulnerable to an escalation from admin to server admin when auth proxy is used, allowing an admin to     take over the server admin account and gain full control of the grafana instance. All installations should     be upgraded as soon as possible. As a workaround deactivate auth proxy following the instructions at:
    https://grafana.com/docs/grafana/latest/setup-grafana/configure-security/configure-authentication/auth-     proxy/ (CVE-2022-35957)

  - Grafana is an open-source platform for monitoring and observability. In versions prior to 8.5.13, 9.0.9,     and 9.1.6, Grafana is subject to Improper Preservation of Permissions resulting in privilege escalation on     some folders where Admin is the only used permission. The vulnerability impacts Grafana instances where     RBAC was disabled and enabled afterwards, as the migrations which are translating legacy folder     permissions to RBAC permissions do not account for the scenario where the only user permission in the     folder is Admin, as a result RBAC adds permissions for Editors and Viewers which allow them to edit and     view folders accordingly. This issue has been patched in versions 8.5.13, 9.0.9, and 9.1.6. A workaround     when the impacted folder/dashboard is known is to remove the additional permissions manually.

  - Grafana is an open-source platform for monitoring and observability. Grafana had a stored XSS     vulnerability in the Graphite FunctionDescription tooltip. The stored XSS vulnerability was possible due     the value of the Function Description was not properly sanitized. An attacker needs to have control over     the Graphite data source in order to manipulate a function description and a Grafana admin needs to     configure the data source, later a Grafana user needs to select a tampered function and hover over the     description. Users may upgrade to version 8.5.22, 9.2.15 and 9.3.11 to receive a fix. (CVE-2023-1410)

    (CVE-2022-36062)

  - Programs which compile regular expressions from untrusted sources may be vulnerable to memory exhaustion     or denial of service. The parsed regexp representation is linear in the size of the input, but in some     cases the constant factor can be as high as 40,000, making relatively small regexps consume much larger     amounts of memory. After fix, each regexp being parsed is limited to a 256 MB memory footprint. Regular     expressions whose representation would use more space than that are rejected. Normal use of regular     expressions is unaffected. (CVE-2022-41715)

  - Prometheus Exporter Toolkit is a utility package to build exporters. Prior to versions 0.7.2 and 0.8.2, if     someone has access to a Prometheus web.yml file and users' bcrypted passwords, they can bypass security by     poisoning the built-in authentication cache. Versions 0.7.2 and 0.8.2 contain a fix for the issue. There     is no workaround, but attacker must have access to the hashed password to use this functionality.
