Red Hat Security Advisory: Kiali 2.11.6 for Red Hat OpenShift Service Mesh 3.1

1. Implementation

   By freezing the object prototype first (for example, Object.freeze(Object.prototype)), modification of the prototype becomes impossible.

2. Architecture and Design

   By blocking modifications of attributes that resolve to object prototype, such as proto or prototype, this weakness can be mitigated.

3. Implementation · Input Validation

   When handling untrusted objects, validating using a schema can be used.

1. Requirements

   Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.

2. Architecture and Design

   Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.

3. Architecture and Design

   Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended.

1. Architecture and Design · Libraries or Frameworks

   Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.

2. Implementation · Architecture and Design

   Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.

3. Architecture and Design · Implementation · Attack Surface Reduction

   Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide…
