Common Weakness Enumeration
CWE-917
AllowedImproper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection')
Abstraction: Base · Status: Incomplete
The product constructs all or part of an expression language (EL) statement in a framework such as 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.
48 vulnerabilities reference this CWE, most recent first.

Title
SurrealDB Injection on Open Notebook
Summary
An improper input validation, together with an overly permissive default CORS configuration in Open Notebook v1.8.1 allows remote attacker to trick a legitimate user to alter or delete arbitrary database entries via specially crafted malicious URL. Depending on the deployment, data exfiltration is also possible.

Summary
A critical Remote Code Execution (RCE) vulnerability was identified in the server-side template rendering mechanism used by the Glassfish gadget handler. The application processes .xml files and evaluates user-supplied values within a context where Expression Language (EL) “expressions” are processed without proper sanitization or escaping. By injecting expressions such as #{7*7}, the server returns 49, confirming server-side EL evaluation. This issue allows a remote attacker to fully compromise the underlying host, enabling capabilities as reading/modifying data, executing arbitrary commands, persistence, and lateral movement. This issue affects Eclipse GlassFish: from 8.0.0 to 8.0.1, fixed in 8.0.2; 7.1.0, fixed in 7.1.1; from 7.0.0 to 7.0.25, fixed in 7.0.26. Impact on versions from 5.1.0 to 6.2.5 is unknown.

Title
Spring Cloud Gateway Webflux SpEL Injection Vulnerability Allowing Exposure of Environment Variables
Summary
The following versions of Spring Cloud Gateway Server Webflux may be vulnerable to the ability to expose environment variables and system properties to attackers.
An application should be considered vulnerable when all the following are true:
* The application is using Spring Cloud Gateway Server Webflux (Spring Cloud Gateway Server WebMVC is not vulnerable).
* An admin or untrusted third party using Spring Expression Language (SpEL) to access environment variables or system properties via routes.
* An untrusted third party could create a route that uses SpEL to access environment variables or system properties if: * The Spring Cloud Gateway Server Webflux actuator web endpoint is enabled via management.endpoints.web.exposure.include=gateway and management.endpoint.gateway.enabled=trueor management.endpoint.gateway.access=unrestricte.
* The actuator endpoints are available to attackers.
* The actuator endpoints are unsecured.

Mitigation
Architecture and Design
Avoid adding user-controlled data into an expression interpreter when possible.
Mitigation
Implementation
- If user-controlled data must be added to an expression interpreter, one or more of the following should be performed:
- Validate that the user input will not evaluate as an expression
- Encode the user input in a way that ensures it is not evaluated as an expression
Mitigation
System Configuration
Operation
The framework or tooling might allow the developer to disable or deactivate the processing of EL expressions, such as setting the isELIgnored attribute for a JSP page to "true".
No CAPEC attack patterns related to this CWE.
