Advisories for Maven/Org.jenkins-Ci.plugins/Script-Security package

Jenkins Script Security Plugin provides a sandbox feature that allows low privileged users to define scripts, including Pipelines, that are generally safe to execute. Calls to code defined inside a sandboxed script are intercepted, and various allowlists are checked to determine whether the call is to be allowed. Multiple sandbox bypass vulnerabilities exist in Script Security Plugin 1335.vf07d9ce377a_e and earlier: Crafted constructor bodies that invoke other constructors can be used …

A sandbox bypass vulnerability involving map constructors in Jenkins Script Security Plugin 1228.vd93135a_2fb_25 and earlier allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.

Jenkins Script Security Plugin 1189.vb_a_b_7c8fd5fde and earlier stores whole-script approvals as the SHA-1 hash of the script, making it vulnerable to collision attacks.

A sandbox bypass vulnerability involving crafted constructor bodies and calls to sandbox-generated synthetic constructors in Jenkins Script Security Plugin 1183.v774b_0b_0a_a_451 and earlier allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.

A sandbox bypass vulnerability involving various casts performed implicitly by the Groovy language runtime in Jenkins Script Security Plugin 1183.v774b_0b_0a_a_451 and earlier allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.

A sandbox bypass vulnerability involving casting an array-like value to an array type in Jenkins Script Security Plugin 1183.v774b_0b_0a_a_451 and earlier allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.

A cross-site request forgery (CSRF) vulnerability in Jenkins Script Security Plugin 1158.v7c1b_73a_69a_08 and earlier allows attackers to have Jenkins send an HTTP request to an attacker-specified webserver.

A sandbox bypass vulnerability exists in Pipeline: Groovy Plugin 2.59 and earlier in groovy-sandbox/src/main/java/org/kohsuke/groovy/sandbox/SandboxTransformer.java, groovy-cps/lib/src/main/java/com/cloudbees/groovy/cps/SandboxCpsTransformer.java that allows attackers with Job/Configure permission, or unauthorized attackers with SCM commit privileges and corresponding pipelines based on Jenkinsfiles set up in Jenkins, to execute arbitrary code on the Jenkins master JVM

A sandbox bypass vulnerability exists in Pipeline: Groovy Plugin 2.61 and earlier in src/main/java/org/jenkinsci/plugins/workflow/cps/CpsFlowDefinition.java, src/main/java/org/jenkinsci/plugins/workflow/cps/CpsGroovyShellFactory.java that allows attackers with Overall/Read permission to provide a pipeline script to an HTTP endpoint that can result in arbitrary code execution on the Jenkins master JVM.

A sandbox bypass vulnerability in Jenkins Script Security Plug allows attackers with permission to define sandboxed scripts to provide crafted return values or script binding content that can result in arbitrary code execution on the Jenkins controller JVM.

Jenkins Script Security Plugin does not correctly escape pending or approved classpath entries on the In-process Script Approval page, resulting in a stored cross-site scripting vulnerability.

Sandbox protection in Jenkins Script Security Plugin could be circumvented through crafted method calls on objects that implement GroovyInterceptable.

Sandbox protection in Jenkins Script Security Plugin could be circumvented through crafted constructor calls and crafted constructor bodies.

Sandbox protection in Jenkins Script Security Plugin could be circumvented during the script compilation phase by applying AST transforming annotations to imports or by using them inside other annotations.

A sandbox bypass vulnerability in Jenkins Script Security Plugin related to the handling of default parameter expressions in closures allows attackers to execute arbitrary code in sandboxed scripts.

A sandbox bypass vulnerability in Jenkins Script Security Plugin related to the handling of default parameter expressions in constructors allows attackers to execute arbitrary code in sandboxed scripts.

A sandbox bypass vulnerability in Jenkins Script Security Plugin related to the handling of subexpressions in increment and decrement expressions not involving actual assignment allows attackers to execute arbitrary code in sandboxed scripts.

A sandbox bypass vulnerability in Jenkins Script Security Plugin related to the handling of method names in method call expressions allows attackers to execute arbitrary code in sandboxed scripts.

A sandbox bypass vulnerability in Jenkins Script Security Plugin related to the handling of property names in property expressions on the left-hand side of assignment expressions allows attackers to execute arbitrary code in sandboxed scripts.

A sandbox bypass vulnerability in Jenkins Script Security Plugin related to the handling of property names in property expressions in increment and decrement expressions allows attackers to execute arbitrary code in sandboxed scripts.

A sandbox bypass vulnerability in Jenkins Script Security Plugin related to the handling of method pointer expressions allows attackers to execute arbitrary code in sandboxed scripts.

A sandbox bypass vulnerability in Jenkins Script Security Plugin related to the handling of type casts allows attackers to execute arbitrary code in sandboxed scripts.

A sandbox bypass vulnerability in Jenkins Script Security Plugin allows attackers to invoke arbitrary constructors in sandboxed scripts.

A sandbox bypass vulnerability exists in Jenkins Script Security Plugin in src/main/java/org/jenkinsci/plugins/scriptsecurity/sandbox/groovy/GroovySandbox.java, src/main/java/org/jenkinsci/plugins/scriptsecurity/sandbox/groovy/SecureGroovyScript.java allowing attackers with Overall/Read permission to execute arbitrary code on the Jenkins master JVM.

A sandbox bypass vulnerability exists in Jenkins Script Security Plugin in RejectASTTransformsCustomizer.java that allows attackers with Overall/Read permission to provide a Groovy script to an HTTP endpoint that can result in arbitrary code execution on the Jenkins master JVM.

A sandbox bypass vulnerability exists in Jenkins Script Security Plugin in src/main/java/org/jenkinsci/plugins/scriptsecurity/sandbox/groovy/SecureGroovyScript.java that allows attackers with Overall/Read permission to provide a Groovy script to an HTTP endpoint that can result in arbitrary code execution on the Jenkins master JVM.

A sandbox bypass vulnerability exists in Script Security Plugin that allows attackers with the ability to provide sandboxed scripts to execute arbitrary code on the Jenkins master JVM.

A sandbox bypass vulnerability exists in Script Security Plugin that allows attackers with Job/Configure permission to execute arbitrary code on the Jenkins master JVM, if plugins using the Groovy sandbox are installed.

Users with the ability to configure sandboxed Groovy scripts are able to use a type coercion feature in Groovy to create new File objects from strings. This allowed reading arbitrary files on the Jenkins master file system. Such a type coercion is now subject to sandbox protection and considered to be a call to the new File(String) constructor for the purpose of in-process script approval.

Script Security Plugin did not apply sandboxing restrictions to constructor invocations via positional arguments list, super constructor invocations, method references, and type coercion expressions. This could be used to invoke arbitrary constructors and methods, bypassing sandbox protection.

The script-security plugin allows circumventing many of the access restrictions implemented in the script sandbox.
