CVE-2022-21707— Incorrect Authorization in wasmCloud

Quick assessment

Affected
wasmCloud wasmcloud-otp
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

wasmcloud-otp是一个 wasmCloud 服务器进程，它安全地托管并为参与者和能力提供者提供调度。 wasmcloud-otp 存在安全漏洞，该漏洞源于在0.52.2之前的版本中，参与者可以绕过能力授权。参与者通常需要声明其入站调用的功能，但是有了这个漏洞，参与者的功能声明不会在接收调用时进行验证。这损害了参与者的安全模型，因为他们可以从链接的功能提供者接收未经授权的调用。

Vulnerability Title
Incorrect Authorization in wasmCloud
Source: CVE Program / CVE List V5
Vulnerability Description
wasmCloud Host Runtime is a server process that securely hosts and provides dispatch for web assembly (WASM) actors and capability providers. In versions prior to 0.52.2 actors can bypass capability authorization. Actors are normally required to declare their capabilities for inbound invocations, but with this vulnerability actor capability claims are not verified upon receiving invocations. This compromises the security model for actors as they can receive unauthorized invocations from linked capability providers. The problem has been patched in versions `0.52.2` and greater. There is no workaround and users are advised to upgrade to an unaffected version as soon as possible.
