Title

CloudBees Jenkins URLTrigger Plugin XML外部实体注入漏洞

Description

CloudBees Jenkins（Hudson Labs）是美国CloudBees公司的一套基于Java开发的持续集成工具。该产品主要用于监控持续的软件版本发布/测试项目和一些定时执行的任务。URLTrigger Plugin是使用在其中的一个用于监控URL调用中的响应情况的插件。 Jenkins URLTrigger Plugin 0.48及之前版本存在XML外部实体注入漏洞。该漏洞源于程序未配置XML解析器以防止XML外部实体（XXE）攻击。具有Job/Configure权限的攻击者可利用该漏洞借助特制的XML文件外部实体从polling Jenkins控制器或服务器端提取机密，造成服务器端请求伪造或拒绝服务。

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
