CVE-2024-28848SpEL Injection in `GET /api/v1/policies/validation/condition/<expr>` in OpenMetadata
High 8.8
In plain English
A high-severity code injection in OpenMetadata from open-metadata. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 7.9% (higher than 95% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
OpenMetadata is a unified platform for discovery, observability, and governance powered by a central metadata repository, in-depth lineage, and seamless team collaboration. The `CompiledRule::validateExpression` method evaluates an SpEL expression using an `StandardEvaluationContext`, allowing the expression to reach and interact with Java classes such as `java.lang.Runtime`, leading to Remote Code Execution. The `/api/v1/policies/validation/condition/<expression>` endpoint passes user-controlled data `CompiledRule::validateExpession` allowing authenticated (non-admin) users to execute arbitrary system commands on the underlaying operating system. In addition, there is a missing authorization check since `Authorizer.authorize()` is never called in the affected path and therefore any authenticated non-admin user is able to trigger this endpoint and evaluate arbitrary SpEL expressions leading to arbitrary command execution. This vulnerability was discovered with the help of CodeQL's Expression language injection (Spring) query and is also tracked as `GHSL-2023-236`. This issue may lead to Remote Code Execution and has been resolved in version 1.2.4. Users are advised to upgrade. There are no known workarounds for this vulnerability.
