Argo CD is a declarative continuous deployment for Kubernetes. All versions of ArgoCD starting from v2.4 have a bug where the ArgoCD repo-server component is vulnerable to a Denial-of-Service attack vector. Specifically, the said component extracts a user-controlled tar.gz file without validating the size of its inner files. As a result, a malicious, low-privileged user can send a malicious tar.gz file that exploits this vulnerability to the repo-server, thereby harming the system's functionality and availability. Additionally, the repo-server is susceptible to another vulnerability due to the fact that it does not check the extracted file permissions before attempting to delete them. Consequently, an attacker can craft a malicious tar.gz archive in a way that prevents the deletion of its inner files when the manifest generation process is completed. A patch for this vulnerability has been released in versions 2.6.15, 2.7.14, and 2.8.3. Users are advised to upgrade. The only way to completely resolve the issue is to upgrade, however users unable to upgrade should configure RBAC (Role-Based Access Control) and provide access for configuring applications only to a limited number of administrators. These administrators should utilize trusted and verified Helm charts.

An uncontrolled resource consumption flaw was found in openstack-neutron. This flaw allows a remote authenticated user to query a list of security groups for an invalid project. This issue creates resources that are unconstrained by the user's quota. If a malicious user were to submit a significant number of requests, this could lead to a denial of service.

ConcreteCMS v9.4.7 contains a Denial of Service (DoS) vulnerability in the File Manager component. The 'download' method in 'concrete/controllers/backend/file.php' improperly manages memory when creating zip archives. It uses 'ZipArchive::addFromString' combined with 'file_get_contents', which loads the entire content of every selected file into PHP memory. An authenticated attacker can exploit this by requesting a bulk download of large files, triggering an Out-Of-Memory (OOM) condition that causes the PHP-FPM process to terminate (SIGSEGV) and the web server to return a 500 error.

Discourse is an open source discussion platform. In affected versions a request to create or update custom sidebar section can cause a denial of service. This issue has been patched in commit `52b003d915`. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. The `SniHandler` can allocate up to 16MB of heap for each channel during the TLS handshake. When the handler or the channel does not have an idle timeout, it can be used to make a TCP server using the `SniHandler` to allocate 16MB of heap. The `SniHandler` class is a handler that waits for the TLS handshake to configure a `SslHandler` according to the indicated server name by the `ClientHello` record. For this matter it allocates a `ByteBuf` using the value defined in the `ClientHello` record. Normally the value of the packet should be smaller than the handshake packet but there are not checks done here and the way the code is written, it is possible to craft a packet that makes the `SslClientHelloHandler`. This vulnerability has been fixed in version 4.1.94.Final.

A vulnerability in a logging API in Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to cause the device to become unresponsive or trigger an unexpected reload. This vulnerability could also allow an attacker with valid user credentials, but not Administrator privileges, to view a system log file that they would not normally have access to. This vulnerability is due to a lack of rate-limiting of requests that are sent to a specific API that is related to an FMC log. An attacker could exploit this vulnerability by sending a high rate of HTTP requests to the API. A successful exploit could allow the attacker to cause a denial of service (DoS) condition due to the FMC CPU spiking to 100 percent utilization or to the device reloading. CPU utilization would return to normal if the attack traffic was stopped before an unexpected reload was triggered.

Fast-csv is an npm package for parsing and formatting CSVs or any other delimited value file in node. In fast-cvs before version 4.3.6 there is a possible ReDoS vulnerability (Regular Expression Denial of Service) when using ignoreEmpty option when parsing. This has been patched in `v4.3.6` You will only be affected by this if you use the `ignoreEmpty` parsing option.

KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. Prior to versions 1.11.1, 1.10.2, and 1.9.4, a large response received by the viaduct WSClient can cause a DoS from memory exhaustion. The entire body of the response is being read into memory which could allow an attacker to send a request that returns a response with a large body. The consequence of the exhaustion is that the process which invokes a WSClient will be in a denial of service. The software is affected If users who are authenticated to the edge side connect to `cloudhub` from the edge side through WebSocket protocol. This bug has been fixed in Kubeedge 1.11.1, 1.10.2, and 1.9.4. There are currently no known workarounds.

An issue was discovered in the CheckUser extension for MediaWiki through 1.39.3. When a user with checkuserlog permissions makes many CheckUserLog API requests in some configurations, denial of service can occur (RequestTimeoutException or upstream request timeout).

SAP NetWeaver AS for ABAP and ABAP Platform - versions 740, 750, 751, 752, 753, 754, 755, 756, 757, 791, allows an attacker authenticated as a non-administrative user to craft a request with certain parameters which can consume the server's resources sufficiently to make it unavailable over the network without any user interaction.

KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. Prior to versions 1.11.1, 1.10.2, and 1.9.4, the CloudCore Router does not impose a limit on the size of responses to requests made by the REST handler. An attacker could use this weakness to make a request that will return an HTTP response with a large body and cause DoS of CloudCore. In the HTTP Handler API, the rest handler makes a request to a pre-specified handle. The handle will return an HTTP response that is then read into memory. The consequence of the exhaustion is that CloudCore will be in a denial of service. Only an authenticated user of the cloud can make an attack. It will be affected only when users enable `router` module in the config file `cloudcore.yaml`. This bug has been fixed in Kubeedge 1.11.1, 1.10.2, and 1.9.4. As a workaround, disable the router switch in the config file `cloudcore.yaml`.

Mikrotik RouterOs before stable 6.47 suffers from an uncontrolled resource consumption in the memtest process. An authenticated remote attacker can cause a Denial of Service due to overloading the systems CPU.

KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. Prior to versions 1.11.1, 1.10.2, and 1.9.4, EdgeCore may be susceptible to a DoS attack on CloudHub if an attacker was to send a well-crafted HTTP request to `/edge.crt`. If an attacker can send a well-crafted HTTP request to CloudHub, and that request has a very large body, that request can crash the HTTP service through a memory exhaustion vector. The request body is being read into memory, and a body that is larger than the available memory can lead to a successful attack. Because the request would have to make it through authorization, only authorized users may perform this attack. The consequence of the exhaustion is that CloudHub will be in denial of service. KubeEdge is affected only when users enable the CloudHub module in the file `cloudcore.yaml`. This bug has been fixed in Kubeedge 1.11.1, 1.10.2, and 1.9.4. As a workaround, disable the CloudHub switch in the config file `cloudcore.yaml`.

A flaw was found in the machine-config-operator that causes an OpenShift node to become unresponsive when a container consumes a large amount of memory. An attacker could use this flaw to deny access to schedule new pods in the OpenShift cluster. This was fixed in openshift/machine-config-operator 4.4.3, openshift/machine-config-operator 4.3.25, openshift/machine-config-operator 4.2.36.

Mattermost fails to unescape Markdown strings in a memory-efficient way, allowing an attacker to cause a Denial of Service by sending a message containing a large number of escaped characters.

KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. Prior to versions 1.11.1, 1.10.2, and 1.9.4, several endpoints in the Cloud AdmissionController may be susceptible to a DoS attack if an HTTP request containing a very large Body is sent to it. The consequence of the exhaustion is that the Cloud AdmissionController will be in denial of service. This bug has been fixed in Kubeedge 1.11.1, 1.10.2, and 1.9.4. There is currently no known workaround.

In a Point-to-Multipoint (P2MP) Label Switched Path (LSP) scenario, an uncontrolled resource consumption vulnerability in the Routing Protocol Daemon (RPD) in Juniper Networks Junos OS allows a specific SNMP request to trigger an infinite loop causing a high CPU usage Denial of Service (DoS) condition.
