Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 5.21.5 版本之前的 REDAXO 存在跨站请求伪造（CSRF）漏洞，原因是其后台在 index.php 中处理 safemode GET 参数时未验证 CSRF 令牌。攻击者可诱使已登录的管理员打开恶意构造的链接，从而禁用全局安全模式（将 config.yml 中的 safe_mode 设置为 false），或启用会话安全模式，进而禁用后台插件。

Vulnerability Title

REDAXO before 5.21.5 CSRF via Safe Mode Toggle Parameter

Source: CVE Program / CVE List V5

Vulnerability Description

REDAXO before 5.21.5 contains a cross-site request forgery vulnerability because the backend processes the safemode GET parameter in index.php without validating a CSRF token. Attackers can lure a logged-in administrator into opening a crafted link to disable global safe mode, writing safe_mode: false to config.yml, or enable session safe mode, disabling backend addons.
