Nama: Missing Origin Validation in WebSockets

Catatan: This makes CSRF attacks more powerful. The consequences will vary depending on the nature of the functionality that is vulnerable to CSRF. An attacker could effectively perform any operations as the victim. If the victim is an administrator or privileged user, the consequences may include obtaining complete control over the web application - deleting or stealing data, uninstalling the product, or using it to launch other attacks against all of the product's users. Because the attacker has the identity of the victim, the scope of the CSRF is limited only by the victim's privileges.

CVE-2020-25095

web console for SIEM product does not check Origin header, allowing Cross Site WebSocket Hijacking (CSWH)

CVE-2018-6651

Chain: gaming client attempts to validate the Origin header, but only uses a substring, allowing Cross-Site WebSocket hijacking by forcing requests from an origin whose hostname is a substring of the valid origin.

CVE-2018-14730

WebSocket server does not check the origin of requests, allowing attackers to steal developer's code using a ws://127.0.0.1:3123/ connection.

CVE-2018-14731

WebSocket server does not check the origin of requests, allowing attackers to steal developer's code using a ws://127.0.0.1/ connection to a randomized port number.

CVE-2018-14732

WebSocket server does not check the origin of requests, allowing attackers to steal developer's code using a ws://127.0.0.1:8080/ connection.

Mitigasi yang Memungkinkan

Phases : Implementation
Enable CORS-like access restrictions by verifying the 'Origin' header during the WebSocket handshake.
Phases : Implementation
Use a randomized CSRF token to verify requests.
Phases : Implementation
Use TLS to securely communicate using 'wss' (WebSocket Secure) instead of 'ws'.
Phases : Architecture and Design // Implementation
Require user authentication prior to the WebSocket connection being established. For example, the WS library in Node has a 'verifyClient' function.
Phases : Implementation
Leverage rate limiting to prevent against DoS. Use of the leaky bucket algorithm can help with this.
Phases : Implementation
Use a library that provides restriction of the payload size. For example, WS library for Node includes 'maxPayloadoption' that can be set.
Phases : Implementation
Treat data/input as untrusted in both directions and apply the same data/input sanitization as XSS, SQLi, etc.

Catatan Pemetaan Kerentanan

Justifikasi : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Komentar : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
