Mattermost fails to properly validate markdown, allowing an attacker to crash the server via a specially crafted markdown input.

Improper input validation in subsystem for Intel(R) AMT versions before 11.8.77, 11.12.77, 11.22.77 and 12.0.64 may allow a privileged user to potentially enable denial of service via network access.

The Premium Addons for Elementor plugin for WordPress is vulnerable to Regular Expression Denial of Service (ReDoS) in all versions up to, and including, 4.10.35. This is due to processing user-supplied input as a regular expression. This makes it possible for authenticated attackers, with Author-level access and above, to create and query a malicious post title, resulting in slowing server resources.

In Tensorflow before versions 2.2.1 and 2.3.1, if a user passes a list of strings to `dlpack.to_dlpack` there is a memory leak following an expected validation failure. The issue occurs because the `status` argument during validation failures is not properly checked. Since each of the above methods can return an error status, the `status` value must be checked before continuing. The issue is patched in commit 22e07fb204386768e5bcbea563641ea11f96ceb8 and is released in TensorFlow versions 2.2.1, or 2.3.1.

In Gallagher Command Centre v8.20 prior to v8.20.1093(MR2) it is possible to create Guard Tour events that when accessed via things like reporting cause clients to temporarily hang or disconnect.

In etcd before versions 3.3.23 and 3.4.10, a large slice causes panic in decodeRecord method. The size of a record is stored in the length field of a WAL file and no additional validation is done on this data. Therefore, it is possible to forge an extremely large frame size that can unintentionally panic at the expense of any RAFT participant trying to decode the WAL.

A flaw was discovered in Wildfly's EJB Client as shipped with Red Hat JBoss EAP 7, where some specific EJB transaction objects may get accumulated over the time and can cause services to slow down and eventaully unavailable. An attacker can take advantage and cause denial of service attack and make services unavailable.

A potential DOS vulnerability was discovered in GitLab CE/EE starting with version 12.6. The container registry name check could cause exponential number of backtracks for certain user supplied values resulting in high CPU usage. Affected versions are: >=12.6, <13.3.9.

For GitLab before 13.0.12, 13.1.6, 13.2.3 a memory exhaustion flaw exists due to excessive logging of an invite email error message.

An issue has been discovered in GitLab EE affecting all versions starting from 8.12. A regular expression related to a file path resulted in the Advanced Search feature susceptible to catastrophic backtracking. Affected versions are >=8.12, <13.3.9,>=13.4, <13.4.5,>=13.5, <13.5.2.

A potential DOS vulnerability was discovered in GitLab versions 13.1, 13.2 and 13.3. The api to update an asset as a link from a release had a regex check which caused exponential number of backtracks for certain user supplied values resulting in high CPU usage.

A vulnerability was found in Openstack Glance. No limits are enforced within the Glance image service for both v1 and v2 `/images` API POST method for authenticated users, resulting in possible denial of service attacks through database table saturation.

Zohocorp ManageEngine Exchange Reporter Plus through 5721 are vulnerable to ReDOS vulnerability in the search module.

Adding a very large number of tags to a runner in GitLab CE/EE affecting all versions prior to 14.7.7, 14.8 prior to 14.8.5, and 14.9 prior to 14.9.2 allows an attacker to impact the performance of GitLab

A resource exhaustion issue was addressed with improved input validation. This issue is fixed in macOS Big Sur 11.0.1. An attacker in a privileged network position may be able to perform denial of service.

Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. A malicious user on a Synapse homeserver X with permission to create certain state events can disable outbound federation from X to an arbitrary homeserver Y. Synapse instances with federation disabled are not affected. In versions of Synapse up to and including 1.73, Synapse did not limit the size of `invite_room_state`, meaning that it was possible to create an arbitrarily large invite event. Synapse 1.74 refuses to create oversized `invite_room_state` fields. Server operators should upgrade to Synapse 1.74 or newer urgently.

Contacts app for Nextcloud easily syncs contacts from various devices with your Nextcloud and allows editing. The unsanitized SVG is converted to a JavaScript blob (in memory data) that the Avatar can't render. Due to this constellation the missing sanitization does not seem to be exploitable. It is recommended that the Contacts app is upgraded to 5.0.3 or 4.2.4

Moxa IKS and EDS allow remote authenticated users to cause a denial of service via a specially crafted packet, which may cause the switch to crash.

HCL BigFix SaaS Authentication Service is affected by a Cross-Site Scripting (XSS) vulnerability. The image upload functionality inadequately validated the submitted image format.

DoS in EdgeMAX EdgeSwitch prior to 1.8.2 allow an Admin user to Crash the SSH CLI interface by using crafted commands.

Connections to external data sources, like e-mail autoconfiguration, were not terminated in case they hit a timeout, instead those connections were logged. Some connections use user-controlled endpoints, which could be malicious and attempt to keep the connection open for an extended period of time. As a result users were able to trigger large amount of egress network connections, possibly exhausting network pool resources and lock up legitimate requests. A new mechanism has been introduced to cancel external connections that might access user-controlled endpoints. No publicly available exploits are known.

Vitess is a database clustering system for horizontal scaling of MySQL through generalized sharding. Prior to version 16.0.2, users can either intentionally or inadvertently create a shard containing `/` characters from VTAdmin such that from that point on, anyone who tries to create a new shard from VTAdmin will receive an error. Attempting to view the keyspace(s) will also no longer work. Creating a shard using `vtctldclient` does not have the same problem because the CLI validates the input correctly. Version 16.0.2, corresponding to version 0.16.2 of the `go` module, contains a patch for this issue. Some workarounds are available. Always use `vtctldclient` to create shards, instead of using VTAdmin; disable creating shards from VTAdmin using RBAC; and/or delete the topology record for the offending shard using the client for your topology server.

Mattermost fails to properly truncate the postgres error log message of a search query failure allowing an attacker to cause the creation of large log files which can result in Denial of Service

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.

Nessus versions 8.6.0 and earlier were found to contain a Denial of Service vulnerability due to improper validation of specific imported scan types. An authenticated, remote attacker could potentially exploit this vulnerability to cause a Nessus scanner to become temporarily unresponsive.

When adding an external mail account, processing of SMTP "capabilities" responses are not limited to plausible sizes. Attacker with access to a rogue SMTP service could trigger requests that lead to excessive resource usage and eventually service unavailability. We now limit accepted SMTP server response to reasonable length/size. No publicly available exploits are known.

When adding an external mail account, processing of IMAP "capabilities" responses are not limited to plausible sizes. Attacker with access to a rogue IMAP service could trigger requests that lead to excessive resource usage and eventually service unavailability. We now limit accepted IMAP server response to reasonable length/size. No publicly available exploits are known.

When adding an external mail account, processing of POP3 "capabilities" responses are not limited to plausible sizes. Attacker with access to a rogue POP3 service could trigger requests that lead to excessive resource usage and eventually service unavailability. We now limit accepted POP3 server response to reasonable length/size. No publicly available exploits are known.

Discourse is an open-source discussion platform. Prior to version 3.0.1 on the `stable` branch and 3.1.0.beta2 on the `beta` and `tests-passed` branches, when submitting a membership request, there is no character limit for the reason provided with the request. This could potentially allow a user to flood the database with a large amount of data. However it is unlikely this could be used as part of a DoS attack, as the paths reading back the reasons are only available to administrators. Starting in version 3.0.1 on the `stable` branch and 3.1.0.beta2 on the `beta` and `tests-passed` branches, a limit of 280 characters has been introduced for membership requests.

An issue was discovered in phpMyAdmin. An authorized user can cause a denial-of-service (DoS) attack on a server by passing large values to a loop. All 4.6.x versions (prior to 4.6.4), 4.4.x versions (prior to 4.4.15.8), and 4.0.x versions (prior to 4.0.10.17) are affected.

Zulip is an open source team chat server. In affected versions Zulip allows organization administrators on a server to configure "linkifiers" that automatically create links from messages that users send, detected via arbitrary regular expressions. Malicious organization administrators could subject the server to a denial-of-service via regular expression complexity attacks; most simply, by configuring a quadratic-time regular expression in a linkifier, and sending messages that exploited it. A regular expression attempted to parse the user-provided regexes to verify that they were safe from ReDoS -- this was both insufficient, as well as _itself_ subject to ReDoS if the organization administrator entered a sufficiently complex invalid regex. Affected users should [upgrade to the just-released Zulip 4.7](https://zulip.readthedocs.io/en/latest/production/upgrade-or-modify.html#upgrading-to-a-release), or [`main`](https://zulip.readthedocs.io/en/latest/production/upgrade-or-modify.html#upgrading-from-a-git-repository).

A vulnerability in the Virtual Shell (VSH) session management for Cisco NX-OS Software could allow an authenticated, remote attacker to cause a VSH process to fail to delete upon termination. This can lead to a build-up of VSH processes that overtime can deplete system memory. When there is no system memory available, this can cause unexpected system behaviors and crashes. The vulnerability is due to the VSH process not being properly deleted when a remote management connection to the device is disconnected. An attacker could exploit this vulnerability by repeatedly performing a remote management connection to the device and terminating the connection in an unexpected manner. A successful exploit could allow the attacker to cause the VSH processes to fail to delete, which can lead to a system-wide denial of service (DoS) condition. The attacker must have valid user credentials to log in to the device using the remote management connection.

A Denial of Service vulnerability exists in the ITMS workflow process manager login window in Symantec IT Management Suite 8.0.

An issue has been discovered in GitLab CE/EE affecting all versions starting from 11.0 before 14.3.6, all versions starting from 14.4 before 14.4.4, all versions starting from 14.5 before 14.5.2. Using large payloads, the diff feature could be used to trigger high load time for users reviewing code changes.

The class file parser in IBM Java 1.4.2 SR13 FP9 allows remote authenticated users to cause a denial of service (memory consumption or an infinite loop) via a crafted attribute length field in a class file, related to validation of a length field at the wrong time, a different vulnerability than CVE-2011-0311.

In Octopus Deploy before 2019.10.6, an authenticated user with TeamEdit permission could send a malformed Team API request that bypasses input validation and causes an application level denial of service condition. (The fix for this was also backported to LTS 2019.9.8 and LTS 2019.6.14.)

Nextcloud calendar is a calendar app for the Nextcloud server platform. Due to missing precondition checks the server was trying to validate strings of any length as email addresses even when megabytes of data were provided, eventually making the server busy and unresponsive. It is recommended that the Nextcloud Calendar app is upgraded to 4.4.4. The only workaround for users unable to upgrade is to disable the calendar app.

A vulnerability was determined in vercel ai up to 3.0.97. The impacted element is the function createJsonResponseHandler/createJsonErrorResponseHandler of the file packages/provider-utils/src/response-handler.ts of the component provider-utils. This manipulation causes resource consumption. The attack may be initiated remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.

The webinstaller is a Golang web server executable that enables the generation of an Auvesy image agent. Resource consumption can be achieved by generating large amounts of installations, which are then saved without limitation in the temp folder of the webinstaller executable.

An issue has been discovered in GitLab affecting all versions starting from 9.0 before 15.7.8, all versions starting from 15.8 before 15.8.4, all versions starting from 15.9 before 15.9.2. It was possible to trigger a resource depletion attack due to improper filtering for number of requests to read commits details.

A user-supplied regular expression in Jenkins Build Failure Analyzer Plugin 1.24.1 and earlier was processed in a way that wasn't interruptible, allowing attackers to have Jenkins evaluate a regular expression without the ability to interrupt this process.

An issue has been discovered in GitLab affecting all versions starting from 15.9 before 15.9.4, all versions starting from 15.10 before 15.10.1. A search timeout could be triggered if a specific HTML payload was used in the issue description.

A vulnerability in the web interface of Cisco Wireless LAN Controller Software could allow a low-privileged, authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability exists due to a failure of the HTTP parsing engine to handle specially crafted URLs. An attacker could exploit this vulnerability by authenticating with low privileges to an affected controller and submitting the crafted URL to the web interface of the affected device. Conversely, an unauthenticated attacker could exploit this vulnerability by persuading a user of the web interface to click the crafted URL. A successful exploit could allow the attacker to cause an unexpected restart of the device, resulting in a DoS condition.

A vulnerability in the Operations, Administration, Maintenance and Provisioning (OAMP) OpsConsole Server for Cisco Unified Customer Voice Portal (CVP) could allow an authenticated, remote attacker to execute Insecure Direct Object Reference actions on specific pages within the OAMP application. The vulnerability is due to insufficient input validation on specific pages of the OAMP application. An attacker could exploit this vulnerability by authenticating to Cisco Unified CVP and sending crafted HTTP requests. A successful exploit could allow an attacker with administrator or read-only privileges to learn information outside of their expected scope. An attacker with administrator privileges could modify certain configuration details of resources outside of their defined scope, which could result in a denial of service (DoS) condition.
