CVE-2026-83542— Apache OFBiz: Unauthenticated RCE via login-page widget injection

Quick assessment

Affected
Apache Software Foundation Apache OFBiz
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache OFBiz 24.09 版本（24.09.08 之前）在所有平台上存在代码生成控制不当（即“代码注入”）漏洞。远程未认证攻击者可通过在 multipart 上传中构造并投放特制的 widget XML 文件，并通过匿名 JSON 请求覆盖管理器登录路由所使用的 mainDecoratorLocation 配置，从而在服务器上执行任意代码。该攻击利用 OFBiz 的实时屏幕描述符机制加载已投放的 XML 文件，并在渲染认证失败页面时执行未沙箱化的 Groovy 表达式。 进一步验证确认以下关键细节： 该

Vulnerability Title
Apache OFBiz: Unauthenticated RCE via login-page widget injection
Source: CVE Program / CVE List V5
Vulnerability Description
Improper Control of Generation of Code ('Code Injection') in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote unauthenticated attacker to execute arbitrary code on the server by staging crafted widget XML in a multipart upload and overriding the mainDecoratorLocation used by a manager login route through an anonymous JSON request, causing OFBiz to load the staged XML through its live screen descriptor mechanism and evaluate an unsandboxed Groovy expression while rendering the authentication-failure page. Further validation established the following: -- The exploit does not require a malformed or incomplete multipart body: a well-formed multipart request that is kept in flight and then allowed to complete normally is sufficient. -- The screen loader reads the widget XML from a live process file descriptor while the upload is streaming, rather than from any file the attacker persists to disk. -- The same underlying issue is also reachable through the public, explicitly unauthenticated /sfa/control/editPortalPageColumnWidth route, returning command output directly in an HTTP 200 response — it is not limited to the login-failure rendering path used in the original report. Users are recommended to upgrade to version 24.09.08, which fixes this issue.
