Quick assessment

Affected
10up Distributor
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.

10up Distributor 插件在 2.3.2 版本之前存在 PHP 对象注入漏洞。该漏洞允许具有“贡献者（Contributor）”权限的用户，通过对分发的帖子元数据执行双重反序列化，实例化任意 PHP 对象。攻击者可以将序列化的 PHP 字符串存储为元数据；当目标站点调用 中的 函数时，该函数会对其进行反序列化，从而在目标站点上存储由攻击者定义的对象。其实际影响取决于目标环境中已加载的“小工具类（gadget classes）”。
