Argo Events is an event-driven workflow automation framework for Kubernetes. Prior to version 1.7.1, several `HandleRoute` endpoints make use of the deprecated `ioutil.ReadAll()`. `ioutil.ReadAll()` reads all the data into memory. As such, an attacker who sends a large request to the Argo Events server will be able to crash it and cause denial of service. A patch for this vulnerability has been released in Argo Events version 1.7.1.
OpenStack Dashboard (Horizon) before 2014.1.3 and 2014.2.x before 2014.2.1 does not properly handle session records when using a db or memcached session engine, which allows remote attackers to cause a denial of service via a large number of requests to the login page.
Play Framework is a web framework for Java and Scala. A denial of service vulnerability has been discovered in verions 2.8.3 through 2.8.15 of Play's forms library, in both the Scala and Java APIs. This can occur when using either the `Form#bindFromRequest` method on a JSON request body or the `Form#bind` method directly on a JSON value. If the JSON data being bound to the form contains a deeply-nested JSON object or array, the form binding implementation may consume all available heap space and cause an `OutOfMemoryError`. If executing on the default dispatcher and `akka.jvm-exit-on-fatal-error` is enabled—as it is by default—then this can crash the application process. `Form.bindFromRequest` is vulnerable when using any body parser that produces a type of `AnyContent` or `JsValue` in Scala, or one that can produce a `JsonNode` in Java. This includes Play's default body parser. This vulnerability been patched in version 2.8.16. There is now a global limit on the depth of a JSON object that can be parsed, which can be configured by the user if necessary. As a workaround, applications that do not need to parse a request body of type `application/json` can switch from the default body parser to another body parser that supports only the specific type of body they expect.
Uncontrolled resource consumption vulnerability in TLS configuration in Synology MailPlus Server before 2.0.5-0606 allows remote attackers to conduct denial-of-service attacks via client-initiated renegotiation.
In CmpBlkDrvTcp of CODESYS V3 in multiple versions an uncontrolled ressource consumption allows an unauthorized attacker to block new TCP connections. Existing connections are not affected.
GE Multilink ML800, ML1200, ML1600, and ML2400 switches with firmware 4.2.1 and earlier and Multilink ML810, ML3000, and ML3100 switches with firmware 5.2.0 and earlier allow remote attackers to cause a denial of service (resource consumption or reboot) via crafted packets.
The documentation of Apache Tomcat 10.1.0-M1 to 10.1.0-M14, 10.0.0-M1 to 10.0.20, 9.0.13 to 9.0.62 and 8.5.38 to 8.5.78 for the EncryptInterceptor incorrectly stated it enabled Tomcat clustering to run over an untrusted network. This was not correct. While the EncryptInterceptor does provide confidentiality and integrity protection, it does not protect against all risks associated with running over any untrusted network, particularly DoS risks.
OPC UA .NET Standard Stack 1.04.368 allows a remote attacker to cause a server to crash via a large number of messages that trigger Uncontrolled Resource Consumption.
In CmpChannelServer of CODESYS V3 in multiple versions an uncontrolled ressource consumption allows an unauthorized attacker to block new communication channel connections. Existing connections are not affected.
The simplepush server iterates through the application installations and pushes a notification to the server provided by deviceToken. But this is user controlled. If a bogus applications is registered with bad deviceTokens, one can generate endless exceptions when those endpoints can't be reached or can slow the server down by purposefully wasting it's time with slow endpoints. Similarly, one can provide whatever HTTP end point they want. This turns the server into a DDOS vector or an anonymizer for the posting of malware and so on.
quic-go through 0.27.0 allows remote attackers to cause a denial of service (CPU consumption) via a Slowloris variant in which incomplete QUIC or HTTP/3 requests are sent. This occurs because mtu_discoverer.go misparses the MTU Discovery service and consequently overflows the probe timer. NOTE: the vendor's position is that this behavior should not be listed as a vulnerability on the CVE List
OPC UA .NET Standard Stack 1.04.368 allows a remote attacker to exhaust the memory resources of a server via a crafted request that triggers Uncontrolled Resource Consumption.
Hawk is an HTTP authentication scheme providing mechanisms for making authenticated HTTP requests with partial cryptographic verification of the request and response, covering the HTTP method, request URI, host, and optionally the request payload. Hawk used a regular expression to parse `Host` HTTP header (`Hawk.utils.parseHost()`), which was subject to regular expression DoS attack - meaning each added character in the attacker's input increases the computation time exponentially. `parseHost()` was patched in `9.0.1` to use built-in `URL` class to parse hostname instead. `Hawk.authenticate()` accepts `options` argument. If that contains `host` and `port`, those would be used instead of a call to `utils.parseHost()`.
On F5 BIG-IP 13.1.x versions prior to 13.1.5, and all versions of 12.1.x and 11.6.x, when multiple route domains are configured, undisclosed requests to big3d can cause an increase in CPU resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated
The Intercluster Sync Agent Service in Cisco Unified Presence Server allows remote attackers to cause a denial of service via a TCP SYN flood, aka Bug ID CSCun34125.
A vulnerability in the SSL/TLS session handler of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a memory leak when closing SSL/TLS connections in a specific state. An attacker could exploit this vulnerability by establishing several SSL/TLS sessions and ensuring they are closed under certain conditions. A successful exploit could allow the attacker to exhaust memory resources in the affected device, which would prevent it from processing new SSL/TLS connections, resulting in a DoS. Manual intervention is required to recover an affected device.
The SSL VPN implementation in Cisco Adaptive Security Appliance (ASA) Software 9.3(.2) and earlier does not properly allocate memory blocks during HTTP packet handling, which allows remote attackers to cause a denial of service (memory consumption) via crafted packets, aka Bug ID CSCuq68888.
On F5 BIG-IP 16.1.x versions prior to 16.1.2.2, when the stream profile is configured on a virtual server, undisclosed requests can cause an increase in memory resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated
A flaw was found in libwebp in versions before 1.0.1. When reading a file libwebp allocates an excessive amount of memory. The highest threat from this vulnerability is to the service availability.
Engine.IO before 4.0.0 allows attackers to cause a denial of service (resource consumption) via a POST request to the long polling transport.
Publify before 8.0.1 is vulnerable to a Denial of Service attack
Lightbend Spray spray-json through 1.3.4 allows remote attackers to cause a denial of service (resource consumption) because of Algorithmic Complexity during the parsing of many JSON object fields (with keys that have the same hash code).
In Moxa NPort 5210, 5230, and 5232 versions 2.9 build 17030709 and prior, the amount of resources requested by a malicious actor are not restricted, allowing for a denial-of-service condition.

It was discovered that the is-my-json-valid JavaScript library used an inefficient regular expression to validate JSON fields defined to have email format. A specially crafted JSON file could cause it to consume an excessive amount of CPU time when validated.
A vulnerability in the packet processing functionality of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to inefficient memory management. An attacker could exploit this vulnerability by sending a high rate of IPv4 or IPv6 traffic through an affected device. This traffic would need to match a configured block action in an access control policy. An exploit could allow the attacker to cause a memory exhaustion condition on the affected device, which would result in a DoS for traffic transiting the device, as well as sluggish performance of the management interface. Once the flood is stopped, performance should return to previous states.
Martem TELEM GW6 and GWM devices with firmware 2018.04.18-linux_4-01-601cb47 and prior allow the creation of new connections to one or more IOAs, without closing them properly, which may cause a denial of service within the industrial process control channel.
LiteCart before 2.1.2 allows remote attackers to cause a denial of service (memory consumption) via URIs that do not exist, because public_html/logs/not_found.log grows without bound, and is loaded into memory for each request.
A vulnerability was found in Braces versions 2.2.0 and above, prior to 2.3.1. Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) attacks.
redhat-certification 7 does not properly restrict the number of recursive definitions of entities in XML documents, allowing an unauthenticated user to run a "Billion Laugh Attack" by replying to XMLRPC methods when getting the status of an host.
An uncontrolled resource consumption flaw has been discovered in redhat-certification in the way documents are loaded. A remote attacker may provide an existing but invalid XML file which would be opened and never closed, possibly producing a Denial of Service.
PowerDNS Authoritative Server 3.3.0 up to 4.1.4 excluding 4.1.5 and 4.0.6, and PowerDNS Recursor 3.2 up to 4.1.4 excluding 4.1.5 and 4.0.9, are vulnerable to a memory leak while parsing malformed records that can lead to remote denial of service.
Bitcoin SV before 0.1.1 allows uncontrolled resource consumption when receiving messages with invalid checksums.
This affects the package jinja2 from 0.0.0 and before 2.11.3. The ReDoS vulnerability is mainly due to the `_punctuation_re regex` operator and its use of multiple wildcards. The last wildcard is the most exploitable as it searches for trailing punctuation. This issue can be mitigated by Markdown to format user content instead of the urlize filter, or by implementing request timeouts and limiting process memory.
Memcached version 1.5.5 contains an Insufficient Control of Network Message Volume (Network Amplification, CWE-406) vulnerability in the UDP support of the memcached server that can result in denial of service via network flood (traffic amplification of 1:50,000 has been reported by reliable sources). This attack appear to be exploitable via network connectivity to port 11211 UDP. This vulnerability appears to have been fixed in 1.5.6 due to the disabling of the UDP protocol by default.
A vulnerability in IPv6 ingress packet processing for Cisco UCS Central Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition due to high CPU utilization on the targeted device. The vulnerability is due to insufficient rate limiting protection for IPv6 ingress traffic. An attacker could exploit this vulnerability by sending the affected device a high rate of IPv6 packets. Successful exploitation could allow the attacker to cause a DoS condition due to CPU and resource constraints. Cisco Bug IDs: CSCuv34544.
YukiWiki 2.1.3 and earlier does not process a particular request properly that may allow consumption of large amounts of CPU and memory resources and may result in causing a denial of service condition.
This affects the package glob-parent before 5.1.2. The enclosure regex used to check for strings ending in enclosure containing path separator.
Triangle MicroWorks SCADA Data Gateway before 3.00.0635 allows remote attackers to cause a denial of service (excessive data processing) via a crafted DNP3 packet.
Mozilla Firefox before 28.0 and SeaMonkey before 2.25 allow remote attackers to cause a denial of service (resource consumption and application hang) via onbeforeunload events that trigger background JavaScript execution.
There is a stack consumption vulnerability in the res_http_websocket.so module of Asterisk through 13.23.0, 14.7.x through 14.7.7, and 15.x through 15.6.0 and Certified Asterisk through 13.21-cert2. It allows an attacker to crash Asterisk via a specially crafted HTTP request to upgrade the connection to a websocket.
An issue was discovered in Asterisk through 19.x. When using STIR/SHAKEN, it is possible to download files that are not certificates. These files could be much larger than what one would expect to download, leading to Resource Exhaustion. This is fixed in 16.25.2, 18.11.2, and 19.3.2.
The qs module before 1.0.0 does not have an option or default for specifying object depth and when parsing a string representing a deeply nested object will block the event loop for long periods of time. An attacker could leverage this to cause a temporary denial-of-service condition, for example, in a web application, other requests would not be processed while this blocking is occurring.
The Security Team noticed that the termination condition of the for loop in the readExternal method is a controllable variable, which, if tampered with, may lead to CPU exhaustion. As a fix, we added an upper bound and termination condition in the read and write logic. We classify it as a "low-priority but useful improvement". SystemDS is a distributed system and needs to serialize/deserialize data but in many code paths (e.g., on Spark broadcast/shuffle or writing to sequence files) the byte stream is anyway protected by additional CRC fingerprints. In this particular case though, the number of decoders is upper-bounded by twice the number of columns, which means an attacker would need to modify two entries in the byte stream in a consistent manner. By adding these checks robustness was strictly improved with almost zero overhead. These code changes are available in versions higher than 2.2.1.
The Googlemaps plugin before 3.1 for Joomla! allows remote attackers to cause a denial of service via the url parameter to plugin_googlemap2_proxy.php.
qpid-cpp: ACL policies only loaded if the acl-file option specified enabling DoS by consuming all available file descriptors
Pexip Infinity before 27.3 allows remote attackers to trigger excessive resource consumption via H.264.
org.cyberneko.html is an html parser written in Java. The fork of `org.cyberneko.html` used by Nokogiri (Rubygem) raises a `java.lang.OutOfMemoryError` exception when parsing ill-formed HTML markup. Users are advised to upgrade to `>= 1.9.22.noko2`. Note: The upstream library `org.cyberneko.html` is no longer maintained. Nokogiri uses its own fork of this library located at https://github.com/sparklemotion/nekohtml and this CVE applies only to that fork. Other forks of nekohtml may have a similar vulnerability.
Katello has a Denial of Service vulnerability in API OAuth authentication
Istio is an open platform to connect, manage, and secure microservices. In affected versions the Istio control plane, istiod, is vulnerable to a request processing error, allowing a malicious attacker that sends a specially crafted message which results in the control plane crashing when the validating webhook for a cluster is exposed publicly. This endpoint is served over TLS port 15017, but does not require any authentication from the attacker. For simple installations, Istiod is typically only reachable from within the cluster, limiting the blast radius. However, for some deployments, especially [external istiod](https://istio.io/latest/docs/setup/install/external-controlplane/) topologies, this port is exposed over the public internet. This issue has been patched in versions 1.13.2, 1.12.5 and 1.11.8. Users are advised to upgrade. Users unable to upgrade should disable access to a validating webhook that is exposed to the public internet or restrict the set of IP addresses that can query it to a set of known, trusted entities.
