Detailsinfo

A vulnerability classified as critical was found in open-metadata OpenMetadata up to 1.2.3. This vulnerability affects the function AlertUtil::validateExpression. The manipulation with an unknown input leads to a code injection vulnerability. The CWE definition for the vulnerability is CWE-94. The 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. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

OpenMetadata is a unified platform for discovery, observability, and governance powered by a central metadata repository, in-depth lineage, and seamless team collaboration. Similarly to the GHSL-2023-250 issue, `AlertUtil::validateExpression` is also called from `EventSubscriptionRepository.prepare()`, which can lead to Remote Code Execution. `prepare()` is called from `EntityRepository.prepareInternal()` which, in turn, gets called from `EntityResource.createOrUpdate()`. Note that, even though there is an authorization check (`authorizer.authorize()`), it gets called after `prepareInternal()` gets called and, therefore, after the SpEL expression has been evaluated. In order to reach this method, an attacker can send a PUT request to `/api/v1/events/subscriptions` which gets handled by `EventSubscriptionResource.createOrUpdateEventSubscription()`. This vulnerability was discovered with the help of CodeQL's Expression language injection (Spring) query. This issue may lead to Remote Code Execution and has been addressed in version 1.2.4. Users are advised to upgrade. There are no known workarounds for this vulnerability. This issue is also tracked as `GHSL-2023-251`.

The advisory is shared for download at github.com. This vulnerability was named CVE-2024-28847 since 03/11/2024. The exploitation appears to be easy. The attack can be initiated remotely.
