CVE-2024-35223
CVSS v3.1
5.3
Medium
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
Dapr versions prior to 1.13.3
Description
Dapr sends the app token of the invoker app instead of the app token of the invoked app when using Dapr as a gRPC proxy for remote service invocation, causing a leak of the application token of the invoker app to the invoked app. This issue impacts Dapr users who use Dapr as a gRPC proxy for remote service invocation as well as the Dapr App API token functionality. An attacker could exploit this vulnerability to gain access to the app token of the invoker app, potentially compromising security and authentication mechanisms.
Recommendations
For versions prior to 1.13.3, update Dapr to version 1.13.3 to resolve the issue. As a temporary workaround, consider restricting access to the gRPC proxy service invocation to minimize the risk of exploitation. Avoid using the
APP API TOKEN in requests between Dapr sidecars until the issue is resolved.Exploit
