CVE-2024-34064

一、漏洞信息
漏洞编号：CVE-2024-34064
漏洞归属组件：python-jinja2
漏洞归属的版本：2.11.2,2.11.3,3.0.3,3.1.2
CVSS V3.0分值：
BaseScore：5.4 Medium
Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N
漏洞简述：
Jinja is an extensible templating engine. The xmlattr filter in affected versions of Jinja accepts keys containing non-attribute characters. XML/HTML attributes cannot contain spaces, /, >, or =, as each would then be interpreted as starting a separate attribute. If an application accepts keys (as opposed to only values) as user input, and renders these in pages that other users see as well, an attacker could use this to inject other attributes and perform XSS. The fix for CVE-2024-22195 only addressed spaces but not other characters. Accepting keys as user input is now explicitly considered an unintended use case of the xmlattr filter, and code that does so without otherwise validating the input should be flagged as insecure, regardless of Jinja version. Accepting values as user input continues to be safe. This vulnerability is fixed in 3.1.4.

二、漏洞分析结构反馈
影响性分析说明：
xmlattr过滤器接受的key为XML/HTML属性不能包含的字符:空格、/、>或=时，将会为每个字符解释为开始的一个单独的属性。如果应用程序接受key（而不仅仅是值）作为用户输入，并将其呈现在其他用户也能看到的页面中，攻击者就可以利用这一点注入其他属性并执行XSS。CVE-2024-22195的修复程序仅解决空格，而不是其他字符。
