Description

There exists an SSRF (Server-Side Request Forgery) vulnerability located at the /sandbox/proxyGateway endpoint. This vulnerability allows us to manipulate arbitrary requests and retrieve corresponding responses by inputting any URL into the requestUrl parameter.

Of particular concern is our ability to exert control over the HTTP method, cookies, IP address, and headers. This effectively grants us the capability to dispatch complete HTTP requests to hosts of our choosing.

This issue affects Apache ShenYu: 2.5.1.

Upgrade to Apache ShenYu 2.6.0 or apply patch  apache/shenyu#4776  .

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
