CVE-2025-52494 1 Adacore 1 Ada Web Server 2025-09-08 7.5 High
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.
CVE-2025-48367 1 Redis 1 Redis 2025-09-05 7.5 High
Redis is an open source, in-memory database that persists on disk. An unauthenticated connection can cause repeated IP protocol errors, leading to client starvation and, ultimately, a denial of service. This vulnerability is fixed in 8.0.3, 7.4.5, 7.2.10, and 6.2.19.
CVE-2025-21605 4 Debian, Lfprojects, Redhat and 1 more 9 Debian Linux, Valkey, Discovery and 6 more 2025-09-05 7.5 High
Redis is an open source, in-memory database that persists on disk. In versions starting at 2.6 and prior to 7.4.3, An unauthenticated client can cause unlimited growth of output buffers, until the server runs out of memory or is killed. By default, the Redis configuration does not limit the output buffer of normal clients (see client-output-buffer-limit). Therefore, the output buffer can grow unlimitedly over time. As a result, the service is exhausted and the memory is unavailable. When password authentication is enabled on the Redis server, but no password is provided, the client can still cause the output buffer to grow from "NOAUTH" responses until the system will run out of memory. This issue has been patched in version 7.4.3. An additional workaround to mitigate this problem without patching the redis-server executable is to block access to prevent unauthenticated users from connecting to Redis. This can be done in different ways. Either using network access control tools like firewalls, iptables, security groups, etc, or enabling TLS and requiring users to authenticate using client side certificates.
CVE-2025-48375 1 Schule111 1 Schule School Management System 2025-09-05 5.3 Medium
Schule is open-source school management system software. Prior to version 1.0.1, the file forgot_password.php (or equivalent endpoint responsible for email-based OTP generation) lacks proper rate limiting controls, allowing attackers to abuse the OTP request functionality. This vulnerability can be exploited to send an excessive number of OTP emails, leading to potential denial-of-service (DoS) conditions or facilitating user harassment through email flooding. Version 1.0.1 fixes the issue.
CVE-2024-37309 1 Cratedb 1 Cratedb 2025-09-04 5.3 Medium
CrateDB is a distributed SQL database. A high-risk vulnerability has been identified in versions prior to 5.7.2 where the TLS endpoint (port 4200) permits client-initiated renegotiation. In this scenario, an attacker can exploit this feature to repeatedly request renegotiation of security parameters during an ongoing TLS session. This flaw could lead to excessive consumption of CPU resources, resulting in potential server overload and service disruption. The vulnerability was confirmed using an openssl client where the command `R` initiates renegotiation, followed by the server confirming with `RENEGOTIATING`. This vulnerability allows an attacker to perform a denial of service attack by exhausting server CPU resources through repeated TLS renegotiations. This impacts the availability of services running on the affected server, posing a significant risk to operational stability and security. TLS 1.3 explicitly forbids renegotiation, since it closes a window of opportunity for an attack. Version 5.7.2 of CrateDB contains the fix for the issue.
CVE-2014-125127 1 Flight Project 1 Flight 2025-09-04 7.5 High
The mikecao/flight PHP framework in versions prior to v1.2 is vulnerable to Denial of Service (DoS) attacks due to eager loading of request bodies in the Request class constructor. The framework automatically reads the entire request body on every HTTP request, regardless of whether the application needs it. An attacker can exploit this by sending requests with large payloads, causing excessive memory consumption and potentially exhausting available server memory, leading to application crashes or service unavailability. The vulnerability was fixed in v1.2 by implementing lazy loading of request bodies.
CVE-2024-58259 1 Suse 1 Rancher 2025-09-03 8.2 High
A vulnerability has been identified within Rancher Manager in which it did not enforce request body size limits on certain public (unauthenticated) and authenticated API endpoints. This allows a malicious user to exploit this by sending excessively large payloads, which are fully loaded into memory during processing, leading to Denial of Service (DoS).
CVE-2024-34358 1 Typo3 1 Typo3 2025-09-03 5.3 Medium
TYPO3 is an enterprise content management system. Starting in version 9.0.0 and prior to versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, and 13.1.1, the `ShowImageController` (`_eID tx_cms_showpic_`) lacks a cryptographic HMAC-signature on the `frame` HTTP query parameter (e.g. `/index.php?eID=tx_cms_showpic?file=3&...&frame=12345`). This allows adversaries to instruct the system to produce an arbitrary number of thumbnail images on the server side. TYPO3 versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, 13.1.1 fix the problem described.
CVE-2025-23028 1 Cilium 1 Cilium 2025-09-03 5.3 Medium
Cilium is a networking, observability, and security solution with an eBPF-based dataplane. A denial of service vulnerability affects versions 1.14.0 through 1.14.7, 1.15.0 through 1.15.11, and 1.16.0 through 1.16.4. In a Kubernetes cluster where Cilium is configured to proxy DNS traffic, an attacker can crash Cilium agents by sending a crafted DNS response to workloads from outside the cluster. For traffic that is allowed but without using DNS-based policy, the dataplane will continue to pass traffic as configured at the time of the DoS. For workloads that have DNS-based policy configured, existing connections may continue to operate, and new connections made without relying on DNS resolution may continue to be established, but new connections which rely on DNS resolution may be disrupted. Any configuration changes that affect the impacted agent may not be applied until the agent is able to restart. This issue is fixed in Cilium v1.14.18, v1.15.12, and v1.16.5. No known workarounds are available.
CVE-2025-32386 1 Helm 1 Helm 2025-09-03 6.5 Medium
Helm is a tool for managing Charts. A chart archive file can be crafted in a manner where it expands to be significantly larger uncompressed than compressed (e.g., >800x difference). When Helm loads this specially crafted chart, memory can be exhausted causing the application to terminate. This issue has been resolved in Helm v3.17.3.
CVE-2025-32873 1 Djangoproject 1 Django 2025-09-02 5.3 Medium
An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().
CVE-2025-3734 1 Stage File Proxy Project 1 Stage File Proxy 2025-09-02 5.9 Medium
Allocation of Resources Without Limits or Throttling vulnerability in Drupal Stage File Proxy allows Flooding.This issue affects Stage File Proxy: from 0.0.0 before 3.1.5.

CVE-2025-4225 1 Gitlab 1 Gitlab 2025-09-02 5.3 Medium
An issue has been discovered in GitLab CE/EE affecting all versions from 14.1 before 18.1.5, 18.2 before 18.2.5, and 18.3 before 18.3.1 that that under certain conditions could have allowed an unauthenticated attacker to cause a denial-of-service condition affecting all users by sending specially crafted GraphQL requests.
CVE-2024-28182 4 Debian, Fedoraproject, Nghttp2 and 1 more 9 Debian Linux, Fedora, Nghttp2 and 6 more 2025-09-02 5.3 Medium
nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream. nghttp2 v1.61.0 mitigates this vulnerability by limiting the number of CONTINUATION frames it accepts per stream. There is no workaround for this vulnerability.
CVE-2024-51461 1 Ibm 1 Qradar Wincollect 2025-09-01 4.3 Medium
IBM QRadar WinCollect Agent 10.0 through 10.1.13 could allow a remote attacker to cause a denial of service by interrupting an HTTP request that could consume memory resources.
CVE-2025-2559 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2025-08-30 4.9 Medium
A flaw was found in Keycloak. When the configuration uses JWT tokens for authentication, the tokens are cached until expiration. If a client uses JWT tokens with an excessively long expiration time, for example, 24 or 48 hours, the cache can grow indefinitely, leading to an OutOfMemoryError. This issue could result in a denial of service condition, preventing legitimate users from accessing the system.
CVE-2025-58058 2025-08-29 5.3 Medium
xz is a pure golang package for reading and writing xz-compressed files. Prior to version 0.5.14, it is possible to put data in front of an LZMA-encoded byte stream without detecting the situation while reading the header. This can lead to increased memory consumption because the current implementation allocates the full decoding buffer directly after reading the header. The LZMA header doesn't include a magic number or has a checksum to detect such an issue according to the specification. Note that the code recognizes the issue later while reading the stream, but at this time the memory allocation has already been done. This issue has been patched in version 0.5.14.
CVE-2025-1000 1 Ibm 1 Db2 2025-08-28 5.3 Medium
IBM Db2 for Linux, UNIX and Windows (includes DB2 Connect Server) 11.5.0 through 11.5.9 and 12.1.0 through 12.1.1 could allow an authenticated user to cause a denial of service when connecting to a z/OS database due to improper handling of automatic client rerouting.
CVE-2025-0915 1 Ibm 1 Db2 2025-08-28 5.3 Medium
IBM Db2 for Linux, UNIX and Windows (includes DB2 Connect Server) 11.5.0 through 11.5.9 and 12.1.0 through 12.1.1 under specific configurations could allow an authenticated user to cause a denial of service due to insufficient release of allocated memory resources.
