A vulnerability was found in Nepxion Discovery (affected version not known) and classified as critical. Affected by this issue is an unknown part of the component SpEL Handler. The manipulation with an unknown input leads to a improper neutralization of special elements used in an expression language statement ('expression language injection') vulnerability. Using CWE to declare the problem leads to CWE-917. The software constructs all or part of an expression language (EL) statement in a Java Server Page (JSP) using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended EL statement before it is executed. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Nepxion Discovery is a solution for Spring Cloud. Discover is vulnerable to SpEL Injection in discovery-commons. DiscoveryExpressionResolver’s eval method is evaluating expression with a StandardEvaluationContext, allowing the expression to reach and interact with Java classes such as java.lang.Runtime, leading to Remote Code Execution. There is no patch available for this issue at time of publication. There are no known workarounds.

The weakness was shared 09/24/2022 as GHSL-2022-033. The advisory is available at This vulnerability is handled as CVE-2022-23463 since 01/19/2022. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 10/23/2022).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
