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.
176 vulnerabilities reference this CWE, most recent first.

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.

Title
JaninoEventEvaluator vulnerability
Summary
ACE vulnerability in JaninoEventEvaluator by QOS.CH logback-core
upto including version 0.1 to 1.3.14 and 1.4.0 to 1.5.12 in Java applications allows
attacker to execute arbitrary code by compromising an existing
logback configuration file or by injecting an environment variable
before program execution.
Malicious logback configuration files can allow the attacker to execute
arbitrary code using the JaninoEventEvaluator extension.
A successful attack requires the user to have write access to a
configuration file. Alternatively, the attacker could inject a malicious
environment variable pointing to a malicious configuration file. In both
cases, the attack requires existing privilege.

Title
Improper Neutralization of Special Elements in mintplex-labs/anything-llm
Summary
Mintplex-Labs' anything-llm application is vulnerable to improper neutralization of special elements used in an expression language statement, identified in the commit id `57984fa85c31988b2eff429adfc654c46e0c342a`. The vulnerability arises from the application's handling of user modifications by managers or admins, allowing for the modification of all existing attributes of the `user` database entity without proper checks or sanitization. This flaw can be exploited to delete user threads, denying users access to their previously submitted data, or to inject fake threads and/or chat history for social engineering attacks.

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".
