CVE-2022-29165 1 Linuxfoundation 1 Argo-cd 2023-12-10 9.3 HIGH 10.0 CRITICAL
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. A critical vulnerability has been discovered in Argo CD starting with version 1.4.0 and prior to versions 2.1.15, 2.2.9, and 2.3.4 which would allow unauthenticated users to impersonate as any Argo CD user or role, including the `admin` user, by sending a specifically crafted JSON Web Token (JWT) along with the request. In order for this vulnerability to be exploited, anonymous access to the Argo CD instance must have been enabled. In a default Argo CD installation, anonymous access is disabled. The vulnerability can be exploited to impersonate as any user or role, including the built-in `admin` account regardless of whether it is enabled or disabled. Also, the attacker does not need an account on the Argo CD instance in order to exploit this. If anonymous access to the instance is enabled, an attacker can escalate their privileges, effectively allowing them to gain the same privileges on the cluster as the Argo CD instance, which is cluster admin in a default installation. This will allow the attacker to create, manipulate and delete any resource on the cluster. They may also exfiltrate data by deploying malicious workloads with elevated privileges, thus bypassing any redaction of sensitive data otherwise enforced by the Argo CD API. A patch for this vulnerability has been released in Argo CD versions 2.3.4, 2.2.9, and 2.1.15. As a workaround, one may disable anonymous access, but upgrading to a patched version is preferable.
CVE-2021-36779 1 Linuxfoundation 1 Longhorn 2023-12-10 8.3 HIGH 9.6 CRITICAL
A Missing Authentication for Critical Function vulnerability in SUSE Longhorn allows any workload in the cluster to execute any binary present in the image on the host without authentication. This issue affects: SUSE Longhorn longhorn versions prior to 1.1.3; longhorn versions prior to 1.2.3.
CVE-2021-45702 1 Linuxfoundation 1 Tremor-script 2023-12-10 5.0 MEDIUM 7.5 HIGH
An issue was discovered in the tremor-script crate before 0.11.6 for Rust. A merge operation may result in a use-after-free.
CVE-2021-36780 1 Linuxfoundation 1 Longhorn 2023-12-10 4.8 MEDIUM 8.1 HIGH
A Missing Authentication for Critical Function vulnerability in longhorn of SUSE Longhorn allows attackers to connect to a longhorn-engine replica instance granting it the ability to read and write data to and from a replica that they should not have access to. This issue affects: SUSE Longhorn longhorn versions prior to 1.1.3; longhorn versions prior to 1.2.3v.
CVE-2021-39143 1 Linuxfoundation 1 Spinnaker 2023-12-10 3.6 LOW 7.1 HIGH
Spinnaker is an open source, multi-cloud continuous delivery platform. A path traversal vulnerability was discovered in uses of TAR files by AppEngine for deployments. This uses a utility to extract files locally for deployment without validating the paths in that deployment don't override system files. This would allow an attacker to override files on the container, POTENTIALLY introducing a MITM type attack vector by replacing libraries or injecting wrapper files. Users are advised to update as soon as possible. For users unable to update disable Google AppEngine deployments and/or disable artifacts that provide TARs.
CVE-2021-41151 1 Linuxfoundation 1 Backstage 2023-12-10 4.0 MEDIUM 4.9 MEDIUM
Backstage is an open platform for building developer portals. In affected versions A malicious actor could read sensitive files from the environment where Scaffolder Tasks are run. The attack is executed by crafting a custom Scaffolder template with a `github:publish:pull-request` action and a particular source path. When the template is executed the sensitive files would be included in the published pull request. This vulnerability is mitigated by the fact that an attacker would need access to create and register templates in the Backstage catalog, and that the attack is very visible given that the exfiltration happens via a pull request. The vulnerability is patched in the `0.15.9` release of `@backstage/plugin-scaffolder-backend`.
CVE-2022-24348 1 Linuxfoundation 1 Argo-cd 2023-12-10 4.0 MEDIUM 7.7 HIGH
Argo CD before 2.1.9 and 2.2.x before 2.2.4 allows directory traversal related to Helm charts because of an error in helmTemplate in repository.go. For example, an attacker may be able to discover credentials stored in a YAML file.
CVE-2021-41272 1 Linuxfoundation 1 Besu 2023-12-10 5.0 MEDIUM 7.5 HIGH
Besu is an Ethereum client written in Java. Starting in version 21.10.0, changes in the implementation of the SHL, SHR, and SAR operations resulted in the introduction of a signed type coercion error in values that represent negative values for 32 bit signed integers. Smart contracts that ask for shifts between approximately 2 billion and 4 billion bits (nonsensical but valid values for the operation) will fail to execute and hence fail to validate. In networks where vulnerable versions are mining with other clients or non-vulnerable versions this will result in a fork and the relevant transactions will not be included in the fork. In networks where vulnerable versions are not mining (such as Rinkeby) no fork will result and the validator nodes will stop accepting blocks. In networks where only vulnerable versions are mining the relevant transaction will not be included in any blocks. When the network adds a non-vulnerable version the network will act as in the first case. Besu 21.10.2 contains a patch for this issue. Besu 21.7.4 is not vulnerable and clients can roll back to that version. There is a workaround available: Once a transaction with the relevant shift operations is included in the canonical chain, the only remediation is to make sure all nodes are on non-vulnerable versions.
CVE-2021-43669 1 Linuxfoundation 1 Fabric 2023-12-10 5.0 MEDIUM 7.5 HIGH
A vulnerability has been detected in HyperLedger Fabric v1.4.0, v2.0.0, v2.0.1, v2.3.0. It can easily break down as many orderers as the attacker wants. This bug can be leveraged by constructing a message whose header is invalid to the interface Order. This bug has been admitted and fixed by the developers of Fabric.
CVE-2021-41190 2 Fedoraproject, Linuxfoundation 3 Fedora, Open Container Initiative Distribution Specification, Open Container Initiative Image Format Specification 2023-12-10 4.0 MEDIUM 5.0 MEDIUM
The OCI Distribution Spec project defines an API protocol to facilitate and standardize the distribution of content. In the OCI Distribution Specification version 1.0.0 and prior, the Content-Type header alone was used to determine the type of document during push and pull operations. Documents that contain both “manifests” and “layers” fields could be interpreted as either a manifest or an index in the absence of an accompanying Content-Type header. If a Content-Type header changed between two pulls of the same digest, a client may interpret the resulting content differently. The OCI Distribution Specification has been updated to require that a mediaType value present in a manifest or index match the Content-Type header used during the push and pull operations. Clients pulling from a registry may distrust the Content-Type header and reject an ambiguous document that contains both “manifests” and “layers” fields or “manifests” and “config” fields if they are unable to update to version 1.0.1 of the spec.
CVE-2021-43832 1 Linuxfoundation 1 Spinnaker 2023-12-10 7.5 HIGH 9.8 CRITICAL
Spinnaker is an open source, multi-cloud continuous delivery platform. Spinnaker has improper permissions allowing pipeline creation & execution. This lets an arbitrary user with access to the gate endpoint to create a pipeline and execute it without authentication. If users haven't setup Role-based access control (RBAC) with-in spinnaker, this enables remote execution and access to deploy almost any resources on any account. Patches are available on the latest releases of the supported branches and users are advised to upgrade as soon as possible. Users unable to upgrade should enable RBAC on ALL accounts and applications. This mitigates the ability of a pipeline to affect any accounts. Block application access unless permission are enabled. Users should make sure ALL application creation is restricted via appropriate wildcards.
CVE-2021-43667 1 Linuxfoundation 1 Fabric 2023-12-10 5.0 MEDIUM 7.5 HIGH
A vulnerability has been detected in HyperLedger Fabric v1.4.0, v2.0.0, v2.1.0. This bug can be leveraged by constructing a message whose payload is nil and sending this message with the method 'forwardToLeader'. This bug has been admitted and fixed by the developers of Fabric. If leveraged, any leader node will crash.
CVE-2021-39228 1 Linuxfoundation 1 Tremor 2023-12-10 7.5 HIGH 9.8 CRITICAL
Tremor is an event processing system for unstructured data. A vulnerability exists between versions 0.7.2 and 0.11.6. This vulnerability is a memory safety Issue when using `patch` or `merge` on `state` and assign the result back to `state`. In this case, affected versions of Tremor and the tremor-script crate maintains references to memory that might have been freed already. And these memory regions can be accessed by retrieving the `state`, e.g. send it over TCP or HTTP. This requires the Tremor server (or any other program using tremor-script) to execute a tremor-script script that uses the mentioned language construct. The issue has been patched in version 0.11.6 by removing the optimization and always cloning the target expression of a Merge or Patch. If an upgrade is not possible, a possible workaround is to avoid the optimization by introducing a temporary variable and not immediately reassigning to `state`.
CVE-2021-41131 1 Linuxfoundation 1 The Update Framework 2023-12-10 8.8 HIGH 8.7 HIGH
python-tuf is a Python reference implementation of The Update Framework (TUF). In both clients (`tuf/client` and `tuf/ngclient`), there is a path traversal vulnerability that in the worst case can overwrite files ending in `.json` anywhere on the client system on a call to `get_one_valid_targetinfo()`. It occurs because the rolename is used to form the filename, and may contain path traversal characters (ie `../../name.json`). The impact is mitigated by a few facts: It only affects implementations that allow arbitrary rolename selection for delegated targets metadata, The attack requires the ability to A) insert new metadata for the path-traversing role and B) get the role delegated by an existing targets metadata, The written file content is heavily restricted since it needs to be a valid, signed targets file. The file extension is always .json. A fix is available in version 0.19 or newer. There are no workarounds that do not require code changes. Clients can restrict the allowed character set for rolenames, or they can store metadata in files named in a way that is not vulnerable: neither of these approaches is possible without modifying python-tuf.
CVE-2021-23450 3 Debian, Linuxfoundation, Oracle 5 Debian Linux, Dojo, Communications Policy Management and 2 more 2023-12-10 7.5 HIGH 9.8 CRITICAL
All versions of package dojo are vulnerable to Prototype Pollution via the setObject function.
CVE-2021-43776 1 Linuxfoundation 1 Auth Backend 2023-12-10 4.3 MEDIUM 6.1 MEDIUM
Backstage is an open platform for building developer portals. In affected versions the auth-backend plugin allows a malicious actor to trick another user into visiting a vulnerable URL that executes an XSS attack. This attack can potentially allow the attacker to exfiltrate access tokens or other secrets from the user's browser. The default CSP does prevent this attack, but it is expected that some deployments have these policies disabled due to incompatibilities. This is vulnerability is patched in version `0.4.9` of `@backstage/plugin-auth-backend`.
CVE-2021-45701 1 Linuxfoundation 1 Tremor-script 2023-12-10 7.5 HIGH 9.8 CRITICAL
An issue was discovered in the tremor-script crate before 0.11.6 for Rust. A patch operation may result in a use-after-free.
CVE-2021-43816 2 Fedoraproject, Linuxfoundation 2 Fedora, Containerd 2023-12-10 6.0 MEDIUM 9.1 CRITICAL
containerd is an open source container runtime. On installations using SELinux, such as EL8 (CentOS, RHEL), Fedora, or SUSE MicroOS, with containerd since v1.5.0-beta.0 as the backing container runtime interface (CRI), an unprivileged pod scheduled to the node may bind mount, via hostPath volume, any privileged, regular file on disk for complete read/write access (sans delete). Such is achieved by placing the in-container location of the hostPath volume mount at either `/etc/hosts`, `/etc/hostname`, or `/etc/resolv.conf`. These locations are being relabeled indiscriminately to match the container process-label which effectively elevates permissions for savvy containers that would not normally be able to access privileged host files. This issue has been resolved in version 1.5.9. Users are advised to upgrade as soon as possible.
CVE-2021-32660 1 Linuxfoundation 1 \@backstage\/techdocs-common 2023-12-10 5.8 MEDIUM 8.1 HIGH
Backstage is an open platform for building developer portals, and techdocs-common contains common functionalities for Backstage's TechDocs. In versions of `@backstage/tehdocs-common` prior to 0.6.4, a malicious internal actor is able to upload documentation content with malicious scripts. These scripts would normally be sanitized by the TechDocs frontend, but by tricking a user to visit the content via the TechDocs API, the content sanitazion will be bypassed. If the TechDocs API is hosted on the same origin as the Backstage app or other backend plugins, this may give access to sensitive data. The ability to upload malicious content may be limited by internal code review processes, unless the chosen TechDocs deployment method is to use an object store and the actor has access to upload files directly to that store. The vulnerability is patched in the `0.6.4` release of `@backstage/techdocs-common`.
CVE-2021-36154 1 Linuxfoundation 1 Grpc Swift 2023-12-10 5.0 MEDIUM 7.5 HIGH
HTTP2ToRawGRPCServerCodec in gRPC Swift 1.1.1 and earlier allows remote attackers to deny service via the delivery of many small messages within a single HTTP/2 frame, leading to Uncontrolled Recursion and stack consumption.
