Triggering this workflow can cause the MOVEit Transfer application to terminate unexpectedly.

A vulnerability in SonicOS CFS (Content filtering service) returns a large 403 forbidden HTTP response message to the source address when users try to access prohibited resource this allows an attacker to cause HTTP Denial of Service (DoS) attack

A lack of rate limiting in the component /Home/UploadStreamDocument of SigningHub v8.6.8 allows attackers to cause a Denial of Service (DoS) via uploading an excessive number of files.

NVIDIA FLARE contains a vulnerability in the admin interface, where an un-authorized attacker can cause Allocation of Resources Without Limits or Throttling, which may lead to cause system unavailable.

Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 22.2.0, Twisted SSH client and server implement is able to accept an infinite amount of data for the peer's SSH version identifier. This ends up with a buffer using all the available memory. The attach is a simple as `nc -rv localhost 22 < /dev/zero`. A patch is available in version 22.2.0. There are currently no known workarounds.

A vulnerability was discovered in GitLab versions before 13.1.10, 13.2.8 and 13.3.4. GitLab Webhook feature could be abused to perform denial of service attacks due to the lack of rate limitation.

An issue was discovered in libexif before 0.6.22. An unrestricted size in handling Canon EXIF MakerNote data could lead to consumption of large amounts of compute time for decoding EXIF data.

A denial-of-service vulnerability exists in the NetX IPv6 component functionality of Eclipse ThreadX NetX Duo. A specially crafted network packet of "Packet Too Big" with more than 15 different source address can lead to denial of service. An attacker can send a malicious packet to trigger this vulnerability.

Apollo Gateway provides utilities for combining multiple GraphQL microservices into a single GraphQL endpoint. Prior to 2.10.1, a vulnerability in Apollo Gateway allowed queries with deeply nested and reused named fragments to be prohibitively expensive to query plan, specifically due to internal optimizations being frequently bypassed. The query planner includes an optimization that significantly speeds up planning for applicable GraphQL selections. However, queries with deeply nested and reused named fragments can generate many selections where this optimization does not apply, leading to significantly longer planning times. Because the query planner does not enforce a timeout, a small number of such queries can render gateway inoperable. This could lead to excessive resource consumption and denial of service. This has been remediated in @apollo/gateway version 2.10.1.

LiteSpeed QUIC (LSQUIC) Library before 4.3.1 has an lsquic_engine_packet_in memory leak.

Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.124.Final and 4.2.4.Final, Netty is vulnerable to MadeYouReset DDoS. This is a logical vulnerability in the HTTP/2 protocol, that uses malformed HTTP/2 control frames in order to break the max concurrent streams limit - which results in resource exhaustion and distributed denial of service. This issue has been patched in versions 4.1.124.Final and 4.2.4.Final.

Mastodon is a free, open-source social network server based on ActivityPub Mastodon which facilitates LDAP configuration for authentication. In versions 3.1.5 through 4.2.24, 4.3.0 through 4.3.11 and 4.4.0 through 4.4.3, Mastodon's rate-limiting system has a critical configuration error where the email-based throttle for confirmation emails incorrectly checks the password reset path instead of the confirmation path, effectively disabling per-email limits for confirmation requests. This allows attackers to bypass rate limits by rotating IP addresses and send unlimited confirmation emails to any email address, as only a weak IP-based throttle (25 requests per 5 minutes) remains active. The vulnerability enables denial-of-service attacks that can overwhelm mail queues and facilitate user harassment through confirmation email spam. This is fixed in versions 4.2.24, 4.3.11 and 4.4.3.

pypdf is a free and open-source pure-python PDF library. Prior to version 6.0.0, an attacker can craft a PDF which leads to the RAM being exhausted. This requires just reading the file if a series of FlateDecode filters is used on a malicious cross-reference stream. Other content streams are affected on explicit access. This issue has been fixed in 6.0.0. If an update is not possible, a workaround involves including the fixed code from pypdf.filters.decompress into the existing filters file.

The ZlibDecoders in Netty 4.1.x before 4.1.46 allow for unbounded memory allocation while decoding a ZlibEncoded byte stream. An attacker could send a large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.

In Ascertia SigningHub through 8.6.8, there is a lack of rate limiting on the invite user function, leading to an email bombing vulnerability. An authenticated attacker can exploit this by automating invite requests.

WeGIA is a web manager for charitable institutions. The Wegia server has a vulnerability that allows excessively long HTTP GET requests to a specific URL. This issue arises from the lack of validation for the length of the errorstr parameter. Tests confirmed that the server processes URLs up to 8,142 characters, resulting in high resource consumption, elevated latency, timeouts, and read errors. This makes the server susceptible to Denial of Service (DoS) attacks. This vulnerability is fixed in 3.3.0.

Chall-Manager is a platform-agnostic system able to start Challenges on Demand of a player. The HTTP Gateway processes headers, but with no timeout set. With a slow loris attack, an attacker could cause Denial of Service (DoS). Exploitation does not require authentication nor authorization, so anyone can exploit it. It should nonetheless not be exploitable as it is highly recommended to bury Chall-Manager deep within the infrastructure due to its large capabilities, so no users could reach the system. Patch has been implemented by commit 1385bd8 and shipped in v0.1.4.

WeGIA is a web manager for charitable institutions. The Wegia server has a vulnerability that allows excessively long HTTP GET requests to a specific URL. This issue arises from the lack of validation for the length of the fid parameter. Tests confirmed that the server processes URLs up to 8,142 characters, resulting in high resource consumption, elevated latency, timeouts, and read errors. This makes the server susceptible to Denial of Service (DoS) attacks. This vulnerability is fixed in 3.3.0.

cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library. Prior to 0.23.0, incoming requests using Transfer-Encoding: chunked in the header can allocate memory arbitrarily in the server, potentially leading to its exhaustion. This vulnerability is fixed in 0.23.0. NOTE: This vulnerability is related to CVE-2025-53628.

A vulnerability was found in Keycloak before 11.0.1 where DoS attack is possible by sending twenty requests simultaneously to the specified keycloak server, all with a Content-Length header value that exceeds the actual byte count of the request body.

Allocation of Resources Without Limits or Throttling vulnerability in Apache Software Foundation Apache Struts.This issue affects Apache Struts: through 2.5.30, through 6.1.2. Upgrade to Struts 2.5.31 or 6.1.2.1 or greater

To keep its cache database efficient, `named` running as a recursive resolver occasionally attempts to clean up the database. It uses several methods, including some that are asynchronous: a small chunk of memory pointing to the cache element that can be cleaned up is first allocated and then queued for later processing. It was discovered that if the resolver is continuously processing query patterns triggering this type of cache-database maintenance, `named` may not be able to handle the cleanup events in a timely manner. This in turn enables the list of queued cleanup events to grow infinitely large over time, allowing the configured `max-cache-size` limit to be significantly exceeded. This issue affects BIND 9 versions 9.16.0 through 9.16.45 and 9.16.8-S1 through 9.16.45-S1.

Vulnerability of system restart triggered by abnormal callbacks passed to APIs.Successful exploitation of this vulnerability may cause the system to restart.

Allocation of Resources Without Limits or Throttling vulnerability in Apache Software Foundation Apache Struts.This issue affects Apache Struts: through 2.5.30, through 6.1.2. Upgrade to Struts 2.5.31 or 6.1.2.1 or greater.

A vulnerability in the cryptographic hardware accelerator driver of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a temporary denial of service (DoS) condition. The vulnerability exists because the affected devices have a limited amount of Direct Memory Access (DMA) memory and the affected software improperly handles resources in low-memory conditions. An attacker could exploit this vulnerability by sending a sustained, high rate of malicious traffic to an affected device to exhaust memory on the device. A successful exploit could allow the attacker to exhaust DMA memory on the affected device, which could cause the device to reload and result in a temporary DoS condition.

A flaw was discovered in Undertow in versions before Undertow 2.1.1.Final where certain requests to the "Expect: 100-continue" header may cause an out of memory error. This flaw may potentially lead to a denial of service.

snappy-java is a fast compressor/decompressor for Java. Due to use of an unchecked chunk length, an unrecoverable fatal error can occur in versions prior to 1.1.10.1. The code in the function hasNextChunk in the fileSnappyInputStream.java checks if a given stream has more chunks to read. It does that by attempting to read 4 bytes. If it wasn’t possible to read the 4 bytes, the function returns false. Otherwise, if 4 bytes were available, the code treats them as the length of the next chunk. In the case that the `compressed` variable is null, a byte array is allocated with the size given by the input data. Since the code doesn’t test the legality of the `chunkSize` variable, it is possible to pass a negative number (such as 0xFFFFFFFF which is -1), which will cause the code to raise a `java.lang.NegativeArraySizeException` exception. A worse case would happen when passing a huge positive value (such as 0x7FFFFFFF), which would raise the fatal `java.lang.OutOfMemoryError` error. Version 1.1.10.1 contains a patch for this issue.

An issue has been discovered in GitLab EE/CE affecting all versions starting before 16.3.6, all versions starting from 16.4 before 16.4.2, all versions starting from 16.5 before 16.5.1 which allows an attackers to block Sidekiq job processor.

A flaw was found in EAP-7 during deserialization of certain classes, which permits instantiation of HashMap and HashTable with no checks on resources consumed. This issue could allow an attacker to submit malicious requests using these classes, which could eventually exhaust the heap and result in a Denial of Service.

A Allocation of Resources Without Limits or Throttling vulnerability in SUSE RKE2 allows attackers with access to K3s servers apiserver/supervisor port (TCP 6443) cause denial of service. This issue affects RKE2: from 1.24.0 before 1.24.17+rke2r1, from v1.25.0 before v1.25.13+rke2r1, from v1.26.0 before v1.26.8+rke2r1, from v1.27.0 before v1.27.5+rke2r1, from v1.28.0 before v1.28.1+rke2r1.

Adacore Ada Web Server (AWS) before 25.2 is vulnerable to a denial-of-service (DoS) condition due to improper handling of SSL handshakes during connection initialization. When a client initiates an HTTPS connection, the server performs the SSL handshake before assigning the connection to a processing slot. However, there is no specific timeout set for this phase, and the server uses the default socket timeout, which is effectively infinite. An attacker can exploit this by sending a malformed TLS ClientHello message with incorrect length values. This causes the server to wait indefinitely for data that never arrives, blocking the worker thread (Line) handling the connection. By opening multiple such connections, up to the server's maximum limit, the attacker can exhaust all available working threads, preventing the server from handling new, legitimate requests.

SmartFTP Client 10.0.2909.0 contains multiple denial of service vulnerabilities that allow attackers to crash the application through specific input manipulation. Attackers can trigger crashes by entering malformed paths, using invalid IP addresses, or clearing connection history in the client's interface.

An Allocation of Resources Without Limits or Throttling vulnerability in SUSE k3s allows attackers with access to K3s servers' apiserver/supervisor port (TCP 6443) cause denial of service. This issue affects k3s: from v1.24.0 before v1.24.17+k3s1, from v1.25.0 before v1.25.13+k3s1, from v1.26.0 before v1.26.8+k3s1, from sev1.27.0 before v1.27.5+k3s1, from v1.28.0 before v1.28.1+k3s1.

TiKV 6.1.2 allows remote attackers to cause a denial of service (fatal error, with RpcStatus UNAVAILABLE for "not leader") upon an attempt to start a node in a situation where the context deadline is exceeded

An issue has been discovered in GitLab EE with Advanced Search affecting all versions from 13.9 to 16.3.6, 16.4 prior to 16.4.2 and 16.5 prior to 16.5.1 that could allow a denial of service in the Advanced Search function by chaining too many syntax operators.

There is a possible denial of service vulnerability in Action View (Rails) <5.2.2.1, <5.1.6.2, <5.0.7.2, <4.2.11.1 where specially crafted accept headers can cause action view to consume 100% cpu and make the server unresponsive.

Rekor is an open source software supply chain transparency log. Rekor prior to version 1.1.1 may crash due to out of memory (OOM) conditions caused by reading archive metadata files into memory without checking their sizes first. Verification of a JAR file submitted to Rekor can cause an out of memory crash if files within the META-INF directory of the JAR are sufficiently large. Parsing of an APK file submitted to Rekor can cause an out of memory crash if the .SIGN or .PKGINFO files within the APK are sufficiently large. The OOM crash has been patched in Rekor version 1.1.1. There are no known workarounds.

An issue was discovered in ebankIT before 7. A Denial-of-Service attack is possible through the GET parameter EStatementsIds located on the /Controls/Generic/EBMK/Handlers/EStatements/DownloadEStatement.ashx endpoint. The GET parameter accepts over 100 comma-separated e-statement IDs without throwing an error. When this many IDs are supplied, the server takes around 60 seconds to respond and successfully generate the expected ZIP archive (during this time period, no other pages load). A threat actor could issue a request to this endpoint with 100+ statement IDs every 30 seconds, potentially resulting in an overload of the server for all users.

A memory exhaustion vulnerability exists in ZIP archive processing. Orthanc automatically extracts ZIP archives uploaded to certain endpoints and trusts metadata fields describing the uncompressed size of archived files. An attacker can craft a small ZIP archive containing a forged size value, causing the server to allocate extremely large buffers during extraction.

Sengled Dimmer Switch V0.0.9 contains a denial of service (DOS) vulnerability, which allows a remote attacker to send malicious Zigbee messages to a vulnerable device and cause crashes. After receiving the malicious command, the device will keep reporting its status and finally drain its battery after receiving the 'Set_short_poll_interval' command.
