Title

PHP拒绝服务漏洞（CNVD-2017-01943）

Description

PHP（PHP：Hypertext Preprocessor，PHP：超文本预处理器）是PHP Group和开放源代码社区共同维护的一种开源的通用计算机脚本语言。该语言支持多重语法、支持多数据库及操作系统和支持C、C++进行程序扩展等。 PHP 7.0.15之前的7.0.x版本和7.1.1之前的7.1.x版本中ext/wddx/wddx.c文件的php_wddx_pop_element函数存在安全漏洞。远程攻击者可借助wddxPacket XML文件中特制的类名利用该漏洞造成拒绝服务（空指针逆向引用和应用程序崩溃）。

CVE-2016-10162 (GCVE-0-2016-10162)

Vulnerability from cvelistv5 – Published: 2017-01-24 21:00 – Updated: 2024-08-06 03:14

Summary

The php_wddx_pop_element function in ext/wddx/wddx.c in PHP 7.0.x before 7.0.15 and 7.1.x before 7.1.1 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an inapplicable class name in a wddxPacket XML document, leading to mishandling in a wddx_deserialize call.

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.
