Adobe Connect | 跨站脚本 (Reflected XSS) (CWE-79)

该 XSS 漏洞的潜在影响非常严重。攻击者可以利用该漏洞在受害者不知情的情况下执行恶意 JavaScript 代码。这可能导致攻击者窃取用户的 Cookie、会话令牌或其他敏感信息，从而完全控制用户的账户。此外，攻击者还可以利用该漏洞重定向用户到恶意网站，或在受害者不知情的情况下执行其他恶意操作。由于该漏洞是反射型 XSS，攻击者需要诱骗受害者访问精心构造的恶意 URL，因此社会工程攻击可能成为利用此漏洞的常见手段。

Organizations heavily reliant on Adobe Connect for webinars, training sessions, or online meetings are particularly at risk. Users with administrative privileges within Adobe Connect are at higher risk, as a successful XSS attack could grant an attacker full control over the system. Shared hosting environments where multiple Adobe Connect instances reside on the same server are also vulnerable, as a compromise of one instance could potentially lead to the compromise of others.

• generic web: Use curl to test potentially vulnerable endpoints with XSS payloads (e.g., <script>alert(1)</script>). Examine the response for signs of script execution.

curl 'https://adobeconnect.example.com/some/vulnerable/page?param=<script>alert(1)</script>' -s

• generic web: Check access and error logs for suspicious requests containing XSS payloads or unusual characters. • adobe: Examine Adobe Connect's configuration files for any custom scripts or plugins that might be vulnerable to XSS. • adobe: Review Adobe Connect's audit logs for any unusual activity or unauthorized access attempts.

最有效的缓解措施是立即将 Adobe Connect 升级到 2025.3 或更高版本，该版本包含此漏洞的修复程序。如果由于兼容性问题无法立即升级，可以考虑以下临时缓解措施：严格审查所有输入数据，并对用户提交的数据进行适当的验证和清理，以防止恶意脚本注入。实施内容安全策略 (CSP) 可以限制浏览器可以加载的资源，从而降低 XSS 攻击的风险。此外，监控 Adobe Connect 服务器的访问日志，以检测可疑活动，并及时采取应对措施。
