Jexl is a scripting (JSR223) language,

var x ='6'; is a valid script, so no invalid compilation should be thrown

When setting value in script's last line the results is the output, for example in Jexl (github) test

The Nashorn engine which provided JavaScript execution capabilities has been removed from Java so the options are in:

Downgrade to the Java version where the feature is there (the lowest Java version which can run JMeter is Java 8)
Use GraalVM which has this JavaScript engine
Consider using a different language for scripting, since JMeter 3.1 you should be using Groovy as it provides maximum performance comparing to other options.

QUESTION

How to disable JEXL assignments?

Asked 2021-Feb-03 at 06:24

I have an application that allows users to enter JEXL expressions. They are used as search filters. A common mistake users do is to write something like "A=5" and expect the filter to be true if and only if the variable A contains the value 5.

Yes, you are right: the = operator is the assignment, and users should have used == for comparison. A workaround like rejecting expressions that match the regular expression [^=]=[^=] would also not allow to compare strings like A=="foo=bar" so it is not the solution.

Is there a chance to remove the assignment operator from a JexlEngine via runtime configuration so it would throw an Exception during parse? Or alternatively find out that the JexlExpression contains an assignment?

...

ANSWER

Answered 2021-Jan-25 at 11:56

So it looks like the JEXL API does not offer any access to the syntax tree or to define the allowed operators. What helped me so far was to modify my implementation of the JexlContext.

By overriding the set method to throw an Exception at least I get an error during runtime. I'd still prefer to have an error at parse-time of the expression, but it saves the day.

There are conflict libraries.

You said in your question that you are using jackson-core-2.10.3.jar

And in your dependency list, I see jackson-core-2.10.3.jar

Two different versions causing the conflict. It could probably be transitive dependency. Exclude the one you don't need.

ANSWER

Answered 2020-Jun-05 at 08:43

JEXL does not use Velocity for parsing; JEXL was inspired by Velocity and JSP/EL (10 years ago). Anyhow, if you are able to use the most current JEXL code (ie compile JEXL 3.2 from the trunk), you should be able to remove the quotes only from the first member of your expression. Example test case follows. Cheers

disableRegistry() doesn't exist (org.apache.tomcat.util.modeler.Registry)

Asked 2020-Mar-25 at 11:17

I updated my project from Spring Boot 1.5.6.RELEASE to 2.2.5.RELEASE and now I get an error claiming that the web server cannot be started because org.apache.tomcat.util.modeler.Registry.disableRegistry() cannot be found. This is a call made by Spring and it's not under my control. I have as dependencies org.apache.tomcat tomcat-servlet-api and org.apache.tomcat tomcat-catalina version 9.0.33, which are pretty new.

The error message itself seems very verbose but I don't really understand what am I supposed to do. I don't think it's my job to tamper with the class path.

As it highlights Caused by: hudson.security.AccessDeniedException2: anonymous is missing the Overall/Administer permission

If re-configuring securing realms is one of option if you are looking at, then probably disabling & re-enabling per your need could be easiest option per : https://jenkins.io/doc/book/system-administration/security/#disabling-security

Two more points:

In case if you are looking at to fix things in file you can edit accordingly at JENKINS_HOME/config.xml

In case if you have earlier configured Authorization strategy was Role-Based Strategy then probably you can try traversing to JENKINS_URL/role-strategy/assign-roles and give 'admin' access to 'Anonymous' and fix things & disable it.
