Red Hat Security Advisory: multicluster engine for Kubernetes v2.11.0 General Availability

Important

A flaw was found in fast-uri. A remote attacker could exploit this vulnerability by crafting a malicious Uniform Resource Identifier (URI) that contains percent-encoded authority delimiters. The fast-uri library incorrectly decodes these delimiters during normalization and then re-emits them as raw separators, which can change the URI's intended authority. This issue allows applications that perform host allowlist checks, redirect validation, or outbound request routing to be steered to a different authority than specified, potentially bypassing security controls.

CWE-140 - Improper Neutralization of Delimiters

A flaw was found in OpenTelemetry-Go, the Go implementation of OpenTelemetry. A remote attacker can exploit this vulnerability by sending multiple 'baggage' header lines. The system's independent parsing and aggregation of each header field-value across multiple values can lead to amplified CPU and memory allocations, resulting in a Denial of Service (DoS).

CWE-770 - Allocation of Resources Without Limits or Throttling

A flaw was found in follow-redirects. When an HTTP request follows a cross-domain redirect (a redirection to a different domain), custom authentication headers, such as X-API-Key or X-Auth-Token, are not properly stripped. This allows these sensitive headers to be forwarded verbatim to the redirect target, potentially leading to the unintended disclosure of authentication information to an untrusted third party.

CWE-212 - Improper Removal of Sensitive Information Before Storage or Transfer

A flaw was found in Axios, an HTTP client library. This vulnerability allows an attacker to exploit a prototype pollution issue if another part of the application has already polluted the Object.prototype. By doing so, the attacker can intercept and modify JSON responses or take control of the HTTP communication. This could lead to unauthorized access to sensitive information like user credentials and request details.

CWE-915 - Improperly Controlled Modification of Dynamically-Determined Object Attributes

A flaw was found in Axios, a software library for making network requests. A remote attacker can exploit a prototype pollution vulnerability to inject arbitrary HTTP headers into outgoing requests. This occurs when the application's core object definitions are manipulated, causing Axios to misinterpret data and include attacker-controlled headers in network communications. This could lead to unauthorized actions or data manipulation.

CWE-915 - Improperly Controlled Modification of Dynamically-Determined Object Attributes

A flaw was found in Axios, a promise-based HTTP client for browsers and Node.js. This vulnerability occurs because the `toFormData` function recursively processes nested objects without a depth limit. A remote attacker can exploit this by sending deeply nested request data, which causes the Node.js process to crash due to a RangeError, leading to a potential Denial of Service (DoS) if the process crashes.

CWE-770 - Allocation of Resources Without Limits or Throttling

A flaw was found in Axios, a promise-based HTTP client. This vulnerability, a Prototype Pollution "Gadget" attack, allows an attacker to manipulate the `Object.prototype.validateStatus` property. By polluting this property, all HTTP error responses (such as 401, 403, or 500) are silently treated as successful responses. This can lead to a complete bypass of application-level authentication and error handling, potentially granting unauthorized access.

CWE-915 - Improperly Controlled Modification of Dynamically-Determined Object Attributes

A flaw was found in Axios, a promise-based HTTP client. An attacker who can control the destination address of an Axios request can exploit this vulnerability. By using specific internal network addresses (within the 127.0.0.0/8 range, excluding 127.0.0.1), the attacker can completely bypass the NO_PROXY protection, potentially leading to unauthorized access or information disclosure within the network. This issue is an incomplete fix for a previous vulnerability.

CWE-918 - Server-Side Request Forgery (SSRF)
