Red Hat Security Advisory: OpenShift Container Platform 4.18.43 security and extras update

Important

A flaw was found in Lodash. A prototype pollution vulnerability in the _.unset and _.omit functions allows an attacker able to control property paths to delete methods from global prototypes. By removing essential functionalities, this can result in a denial of service.

CWE-1321 - Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')

A flaw was found in qs, a module used for parsing query strings. A remote attacker can exploit an improper input validation vulnerability by sending specially crafted HTTP requests that use bracket notation (e.g., `a[]=value`). This bypasses the `arrayLimit` option, which is designed to limit the size of parsed arrays and prevent resource exhaustion. Successful exploitation can lead to memory exhaustion, causing a Denial of Service (DoS) where the application crashes or becomes unresponsive, making the service unavailable to users.

CWE-770 - Allocation of Resources Without Limits or Throttling

A flaw was found in the archive/tar package in the Go standard library. tar.Reader does not set a maximum size on the number of sparse region data blocks in GNU tar pax 1.0 sparse files. A specially crafted tar archive with a pax header indicating a big number of sparse regions can cause a Go program to try to allocate a large amount of memory, causing an out-of-memory condition and resulting in a denial of service.

CWE-770 - Allocation of Resources Without Limits or Throttling

A flaw was found in lodash. The fix for CVE-2021-23337 added validation for the variable option in _.template but did not apply the same validation to options.imports key names. Both paths flow into the same Function() constructor sink. Additionally, _.template uses assignInWith to merge imports, which enumerates inherited properties via for..in. If Object.prototype has been polluted by any other vector, the polluted keys are copied into the imports object and passed to Function().

CWE-94 - Improper Control of Generation of Code ('Code Injection')

A cross site scripting flaw has been discovered in the npm react-router and @remix-run/router packages. React Router (and Remix v1/v2) SPA open navigation redirects originating from loaders or actions in Framework Mode, Data Mode, or the unstable RSC modes can result in unsafe URLs causing unintended javascript execution on the client. This is only an issue if you are creating redirect paths from untrusted content or via an open redirect.

CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
