Title

WordPress访问限制绕过漏洞

Description

WordPress是一种使用PHP语言开发的博客平台，用户可以在支持PHP和MySQL数据库的服务器上架设属于自己的网站，也可以把 WordPress当作一个内容管理系统（CMS）来使用。 WordPress 4.9.1之前的版本中存在访问限制绕过漏洞。该漏洞产生的原因是WordPress中的wp-admin/user-new.php将newbloguser密钥设置为可以直接从用户ID获取的字符串。远程攻击者可通过输入该字符串绕过预期的访问限制。

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
