Synopsis

The remote Red Hat CoreOS host is missing one or more security updates for OpenShift Container Platform 4.9.56.

Description

The remote Red Hat Enterprise Linux CoreOS 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:0777 advisory.

- PKCE support is not implemented in accordance with the RFC for OAuth 2.0 for Native Apps. Without the use of PKCE, the authorization code returned by an authorization server is not enough to guarantee that the client that issued the initial authorization request is the one that will be authorized. An attacker is able to obtain the authorization code using a malicious app on the client-side and use it to gain authorization to the protected resource. This affects the package com.google.oauth-client:google-oauth- client before 1.31.0. (CVE-2020-7692)

- SnakeYaml's Constructor() class does not restrict types which can be instantiated during deserialization.
Deserializing yaml content provided by an attacker can lead to remote code execution. We recommend using SnakeYaml's SafeConsturctor when parsing untrusted content to restrict deserialization. We recommend upgrading to version 2.0 and beyond. (CVE-2022-1471)

- In Eclipse Jetty HTTP/2 server implementation, when encountering an invalid HTTP/2 request, the error handling has a bug that can wind up not properly cleaning up the active connections and associated resources. This can lead to a Denial of Service scenario where there are no enough resources left to process good requests. (CVE-2022-2048)

- The package org.yaml:snakeyaml from 0 and before 1.31 are vulnerable to Denial of Service (DoS) due missing to nested depth limitation for collections. (CVE-2022-25857)

- A cross-site request forgery (CSRF) vulnerability in Jenkins Script Security Plugin 1158.v7c1b_73a_69a_08 and earlier allows attackers to have Jenkins send an HTTP request to an attacker-specified webserver.
(CVE-2022-30946)

- Jenkins Pipeline SCM API for Blue Ocean Plugin 1.25.3 and earlier allows attackers with Job/Configure permission to access credentials with attacker-specified IDs stored in the private per-user credentials stores of any attacker-specified user in Jenkins. (CVE-2022-30952)

- A cross-site request forgery (CSRF) vulnerability in Jenkins Blue Ocean Plugin 1.25.3 and earlier allows attackers to connect to an attacker-specified HTTP server. (CVE-2022-30953)

- Jenkins Blue Ocean Plugin 1.25.3 and earlier does not perform a permission check in several HTTP endpoints, allowing attackers with Overall/Read permission to connect to an attacker-specified HTTP server. (CVE-2022-30954)

- In Jenkins 2.355 and earlier, LTS 2.332.3 and earlier, an observable timing discrepancy on the login form allows distinguishing between login attempts with an invalid username, and login attempts with a valid username and wrong password, when using the Jenkins user database security realm. (CVE-2022-34174)

- A cross-site request forgery (CSRF) vulnerability in Jenkins Git Plugin 4.11.3 and earlier allows attackers to trigger builds of jobs configured to use an attacker-specified Git repository and to cause them to check out an attacker-specified commit. (CVE-2022-36882)

- A missing permission check in Jenkins Git Plugin 4.11.3 and earlier allows unauthenticated attackers to trigger builds of jobs configured to use an attacker-specified Git repository and to cause them to check out an attacker-specified commit. (CVE-2022-36883)

- The webhook endpoint in Jenkins Git Plugin 4.11.3 and earlier provide unauthenticated attackers information about the existence of jobs configured to use an attacker-specified Git repository.
(CVE-2022-36884)

- Jenkins GitHub Plugin 1.34.4 and earlier uses a non-constant time comparison function when checking whether the provided and computed webhook signatures are equal, allowing attackers to use statistical methods to obtain a valid webhook signature. (CVE-2022-36885)

- A sandbox bypass vulnerability involving various casts performed implicitly by the Groovy language runtime in Jenkins Script Security Plugin 1183.v774b_0b_0a_a_451 and earlier allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM. (CVE-2022-43401)

- A sandbox bypass vulnerability involving various casts performed implicitly by the Groovy language runtime in Jenkins Pipeline: Groovy Plugin 2802.v5ea_628154b_c2 and earlier allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM. (CVE-2022-43402)

- A sandbox bypass vulnerability involving casting an array-like value to an array type in Jenkins Script Security Plugin 1183.v774b_0b_0a_a_451 and earlier allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM. (CVE-2022-43403)

- A sandbox bypass vulnerability involving crafted constructor bodies and calls to sandbox-generated synthetic constructors in Jenkins Script Security Plugin 1183.v774b_0b_0a_a_451 and earlier allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM. (CVE-2022-43404)

- A sandbox bypass vulnerability in Jenkins Pipeline: Groovy Libraries Plugin 612.v84da_9c54906d and earlier allows attackers with permission to define untrusted Pipeline libraries and to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM. (CVE-2022-43405)

- A sandbox bypass vulnerability in Jenkins Pipeline: Deprecated Groovy Libraries Plugin 583.vf3b_454e43966 and earlier allows attackers with permission to define untrusted Pipeline libraries and to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM. (CVE-2022-43406)

- Jenkins Pipeline: Input Step Plugin 451.vf1a_a_4f405289 and earlier does not restrict or sanitize the optionally specified ID of the 'input' step, which is used for the URLs that process user interactions for the given 'input' step (proceed or abort) and is not correctly encoded, allowing attackers able to configure Pipelines to have Jenkins build URLs from 'input' step IDs that would bypass the CSRF protection of any target URL in Jenkins when the 'input' step is interacted with. (CVE-2022-43407)

- Jenkins Pipeline: Stage View Plugin 2.26 and earlier does not correctly encode the ID of 'input' steps when using it to generate URLs to proceed or abort Pipeline builds, allowing attackers able to configure Pipelines to specify 'input' step IDs resulting in URLs that would bypass the CSRF protection of any target URL in Jenkins. (CVE-2022-43408)

- Jenkins Pipeline: Supporting APIs Plugin 838.va_3a_087b_4055b and earlier does not sanitize or properly encode URLs of hyperlinks sending POST requests in build logs, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to create Pipelines. (CVE-2022-43409)

- Class org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider in Apache MINA SSHD <= 2.9.1 uses Java deserialization to load a serialized java.security.PrivateKey. The class is one of several implementations that an implementor using Apache MINA SSHD can choose for loading the host keys of an SSH server. (CVE-2022-45047)

- Jenkins Script Security Plugin 1189.vb_a_b_7c8fd5fde and earlier stores whole-script approvals as the SHA-1 hash of the script, making it vulnerable to collision attacks. (CVE-2022-45379)

- Jenkins JUnit Plugin 1159.v0b_396e1e07dd and earlier converts HTTP(S) URLs in test report output to clickable links in an unsafe manner, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission. (CVE-2022-45380)

- Jenkins Pipeline Utility Steps Plugin 2.13.1 and earlier does not restrict the set of enabled prefix interpolators and bundles versions of Apache Commons Configuration library that enable the 'file:' prefix interpolator by default, allowing attackers able to configure Pipelines to read arbitrary files from the Jenkins controller file system. (CVE-2022-45381)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
