Description
A chained attack via SQL Expressions and a Grafana Enterprise plugin can lead to a remote arbitrary code execution impact (RCE). This is enabled by a feature in Grafana (OSS), so all users are always recommended to update to avoid future attack vectors going this path. Only instances with the sqlExpressions feature toggle enabled are vulnerable. Only instances in the following version ranges are affected: - 11.6.0 (inclusive) to 11.6.14 (exclusive): 11.6.14 has the fix. 11.5 and below are not affected. - 12.0.0 (inclusive) to 12.1.10 (exclusive): 12.1.10 has the fix. 12.0 did not receive an update, as it is end-of-life. - 12.2.0 (inclusive) to 12.2.8 (exclusive): 12.2.8 has the fix. - 12.3.0 (inclusive) to 12.3.6 (exclusive): 12.3.6 has the fix. - 12.4.0 (inclusive) to 12.4.2 (exclusive): 12.4.2 has the fix. 13.0.0 and above also have the fix: no v13 release is affected.

Weaknesses
CWE · root cause- CWE-94Improper Control of Generation of CodeThe product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
- CWE-89Improper Neutralization of Special Elements used in an SQL CommandThe product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
Affected systems
Known conditions: network-reachable, administrative account, no user interaction (CVSS vector). Other conditions: not stated in public data.
