Versa Director 缺陷导致 API 被利用，影响 SD-WAN 客户

Versa Director 中的漏洞绝非小事，因为该平台管理 Versa SD-WAN 软件的网络配置

A vulnerability in Versa Networks’ Versa Director, used by internet service providers (ISPs) and managed service providers (MSPs) to manage network configurations for Versa’s SD-WAN software, has been disclosed by the Cybersecurity and Infrastructure Security Agency (CISA). The vulnerability, tracked as CVE-2024-45229, is rated 6.6 in severity and affects five versions of the software.

网络安全和基础设施安全局 (CISA) 披露了 Versa Networks Versa Director 中的一个漏洞，互联网服务提供商 (ISP) 和托管服务提供商 (MSP) 使用该软件来管理 Versa SD-WAN 软件的网络配置。该漏洞的编号为 CVE-2024-45229，严重程度为 6.6，影响该软件的五个版本。

Organizations using vulnerable versions are advised to take immediate action to protect their networks by upgrading to a newer version. The advisory follows a high-severity vulnerability last month, CVE-2024-39717, which was used to attack downstream customers in a supply chain attack.

建议使用易受攻击版本的组织立即采取行动，通过升级到新版本来保护其网络。该通报是在上个月出现一个高严重性漏洞 CVE-2024-39717 后发布的，该漏洞被用来在供应链攻击中攻击下游客户。

Cyble’s ODIN scanner currently shows 73 internet-exposed Versa Director instances, though it is not clear how many of them contain the latest vulnerability.

Cyble 的 ODIN 扫描器当前显示了 73 个暴露在互联网上的 Versa Director 实例，但尚不清楚其中有多少包含最新漏洞。

Versa Director Flaw Leads to API Exploit

Versa Director 缺陷导致 API 被利用

Versa Director’s REST APIs are designed to facilitate automation and streamline operations through a unified interface, enabling IT teams to configure and monitor their network systems more efficiently. However, a flaw in the implementation of these APIs allows for improper input validation, Cyble threat intelligence researchers explained in a blog post.

Versa Director 的 REST API 旨在通过统一的界面促进自动化和简化操作，使 IT 团队能够更有效地配置和监控其网络系统。然而，Cyble 威胁情报研究人员在博客文章中解释说，这些 API 的实现中存在缺陷，导致输入验证不当。

The APIs in question are designed to not require authentication by default, making them accessible to anyone with network connectivity. An attacker could exploit this vulnerability by sending a specially crafted GET request to a Versa Director instance that is directly connected to the internet.

这些 API 的设计默认不需要身份验证，任何有网络连接的人都可以访问它们。攻击者可以通过向直接连接到互联网的 Versa Director 实例发送特制的 GET 请求来利用此漏洞。

“For Versa Directors connected directly to the Internet, attackers could potentially exploit this vulnerability by injecting invalid arguments into a GET request,” Cyble said. “This could expose authentication tokens of currently logged-in users, which can then be used to access additional APIs on port 9183.”

Cyble 表示：“对于直接连接到互联网的 Versa 控制器，攻击者可能会通过向 GET 请求中注入无效参数来利用此漏洞。” “这可能会暴露当前登录用户的身份验证令牌，然后可以使用该令牌访问端口 9183 上的其他 API。”

While the exploit itself does not reveal user credentials, “the implications of token exposure could lead to broader security breaches.”

虽然该漏洞本身不会泄露用户凭据，但“令牌暴露的影响可能会导致更广泛的安全漏洞。”

“The exposure of these tokens can allow attackers to access additional APIs,” Cyble said. “Such unauthorized access could facilitate broader security breaches, potentially impacting sensitive data and operational integrity.”

Cyble 表示：“这些代币的暴露可以让攻击者访问其他 API。” “这种未经授权的访问可能会导致更广泛的安全漏洞，可能会影响敏感数据和操作完整性。”

Versa suggests that a web application firewall (WAF) or API gateway could be used to protect internet-exposed Versa Director instances by blocking access to the URLs of the vulnerable APIs (/vnms/devicereg/device/* on ports 9182 and 9183 and /versa/vnms/devicereg/device/* on port 443).

Versa 建议使用 Web 应用程序防火墙 (WAF) 或 API 网关，通过阻止访问易受攻击的 API 的 URL（端口 9182 和 9183 上的 /vnms/devicereg/device/* 和 /反之亦然/vnms/devicereg/device/* 在端口 443 上）。

Affected Versa Director Versions

受影响的 Versa Director 版本

The vulnerability affects multiple versions of Versa Director, specifically those released before Sept. 9, 2024. This includes versions 22.1.4, 22.1.3, and 22.1.2, as well as all versions of 22.1.1, 21.2.3, and 21.2.2.

该漏洞影响 Versa Director 的多个版本，特别是 2024 年 9 月 9 日之前发布的版本。其中包括版本 22.1.4、22.1.3 和 22.1.2，以及 22.1.1、21.2.3 和 22.1.3 的所有版本。 21.2.2.

Versions released on Sept. 12 and later contain a hot fix for the vulnerability.

9月12日及之后发布的版本包含针对该漏洞的热修复。

The flaw primarily stems from APIs that, by design, do not require authentication. These include interfaces for logging in, displaying banners, and registering devices.

该缺陷主要源于 API 在设计上不需要身份验证。其中包括用于登录、显示横幅和注册设备的界面。
