Adobe Connect | 跨站脚本攻击 (存储型 XSS) (CWE-79)

此 XSS 漏洞的潜在影响非常严重。攻击者可以利用它来执行恶意 JavaScript 代码，从而劫持用户的会话。这可能导致攻击者访问用户的敏感数据，例如会议记录、个人资料信息，甚至控制用户的 Adobe Connect 帐户。攻击者还可以利用此漏洞进行钓鱼攻击，诱骗用户输入凭据或下载恶意软件。由于漏洞是存储型的，攻击者无需直接与受害者交互即可触发漏洞，只需将恶意脚本注入到系统中，受害者访问相关页面时即可触发。

Organizations and individuals using Adobe Connect for online meetings, webinars, and training sessions are at risk. This includes educational institutions, businesses, and government agencies. Those relying on legacy Adobe Connect deployments or those with inadequate input validation practices are particularly vulnerable.

• adobe / server: Examine Adobe Connect server logs for unusual JavaScript execution patterns or suspicious form submissions.

 grep -i 'script' /var/log/adobe/connect/server.log

• generic web: Use curl to test form fields for XSS vulnerabilities.

curl -X POST -d "<script>alert('XSS')</script>" https://<adobeconnect_server>/<vulnerable_form>

• generic web: Check response headers for Content-Security-Policy (CSP) directives. A strong CSP can mitigate XSS attacks.

最有效的缓解措施是立即将 Adobe Connect 升级至 12.6 或更高版本。如果升级会造成中断，可以考虑临时禁用受影响的表单字段，或者实施严格的输入验证和输出编码规则，以防止恶意脚本注入。此外，建议实施 Web 应用防火墙 (WAF) 或代理服务器，以检测和阻止潜在的 XSS 攻击。监控 Adobe Connect 日志，查找可疑活动，例如异常的 JavaScript 执行或未经授权的表单提交。
