Title

Plex Media Server's SSDP XML外部实体注入漏洞

Description

Plex Media Server是一款支持多平台的多媒体娱乐播放器。 Plex Media Server's SSDP存在XML外部实体注入漏洞，同一LAN上未经身份验证的攻击者可以将此漏洞使用与运行Plex的用户帐户相同的权限从文件系统访问任意文件；启动SMB连接以捕获NetNTLM质询/响应并破解明文密码；启动SMB连接以中继NetNTLM质询/响应并在Windows域中实现远程命令执行。

CVE-2018-13415 (GCVE-0-2018-13415)

Vulnerability from cvelistv5 – Published: 2018-08-13 17:00 – Updated: 2024-08-05 09:00

Summary

In Plex Media Server 1.13.2.5154, the XML parsing engine for SSDP/UPnP functionality is vulnerable to an XML External Entity Processing (XXE) attack. Remote, unauthenticated attackers can use this vulnerability to: (1) Access arbitrary files from the filesystem with the same permission as the user account running Plex, (2) Initiate SMB connections to capture a NetNTLM challenge/response and crack to cleartext password, or (3) Initiate SMB connections to relay a NetNTLM challenge/response and achieve Remote Command Execution in Windows domains.

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.

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.
