Summary
Missing release of resource after effective lifetime (CWE-772) in the Controller 7000 resulted in HBUS connected T-Series readers to not automatically recover after coming under attack over the RS-485 interface, resulting in a persistent denial of service. This issue affects: All variants of the Gallagher Controller 7000 9.00 prior to vCR9.00.231204b (distributed in 9.00.1507(MR1)), 8.90 prior to vCR8.90.240209b (distributed in 8.90.1751 (MR3)), 8.80 prior to vCR8.80.240209a (distributed in 8.80.1526 (MR4)), 8.70 prior to vCR8.70.240209a (distributed in 8.70.2526 (MR6)).

CVE-2024-39562 (GCVE-0-2024-39562)

Vulnerability from cvelistv5 – Published: 2024-07-10 22:47 – Updated: 2024-08-02 04:26

Title
Junos OS Evolved: A high rate of SSH connections causes a Denial of Service
Summary
A Missing Release of Resource after Effective Lifetime vulnerability the xinetd process, responsible for spawning SSH daemon (sshd) instances, of Juniper Networks Junos OS Evolved allows an unauthenticated network-based attacker to cause a Denial of Service (DoS) by blocking SSH access for legitimate users. Continued receipt of these connections will create a sustained Denial of Service (DoS) condition. The issue is triggered when a high rate of concurrent SSH requests are received and terminated in a specific way, causing xinetd to crash, and leaving defunct sshd processes. Successful exploitation of this vulnerability blocks both SSH access as well as services which rely upon SSH, such as SFTP, and Netconf over SSH. Once the system is in this state, legitimate users will be unable to SSH to the device until service is manually restored.  See WORKAROUND section below. Administrators can monitor an increase in defunct sshd processes by utilizing the CLI command:   > show system processes | match sshd   root   25219 30901 0 Jul16 ?       00:00:00 [sshd] <defunct> This issue affects Juniper Networks Junos OS Evolved: * All versions prior to 21.4R3-S7-EVO * 22.3-EVO versions prior to 22.3R2-S2-EVO, 22.3R3-S2-EVO; * 22.4-EVO versions prior to 22.4R3-EVO; * 23.2-EVO versions prior to 23.2R2-EVO. This issue does not affect Juniper Networks Junos OS Evolved 22.1-EVO nor 22.2-EVO.

CVE-2024-49769 (GCVE-0-2024-49769)

Vulnerability from cvelistv5 – Published: 2024-10-29 14:18 – Updated: 2024-11-17 00:11

Title
Waitress has a denial of service leading to high CPU usage/resource exhaustion
Summary
Waitress is a Web Server Gateway Interface server for Python 2 and 3. When a remote client closes the connection before waitress has had the opportunity to call getpeername() waitress won't correctly clean up the connection leading to the main thread attempting to write to a socket that no longer exists, but not removing it from the list of sockets to attempt to process. This leads to a busy-loop calling the write function. A remote attacker could run waitress out of available sockets with very little resources required. Waitress 3.0.1 contains fixes that remove the race condition.

CVE-2024-52303 (GCVE-0-2024-52303)

Vulnerability from cvelistv5 – Published: 2024-11-18 20:08 – Updated: 2024-11-19 14:45
VLAI
Title
aiohttp memory leak when middleware is enabled when requesting a resource with a non-allowed method
Summary
aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. In versions starting with 3.10.6 and prior to 3.10.11, a memory leak can occur when a request produces a MatchInfoError. This was caused by adding an entry to a cache on each request, due to the building of each MatchInfoError producing a unique cache entry. An attacker may be able to exhaust the memory resources of a server by sending a substantial number (100,000s to millions) of such requests. Those who use any middlewares with aiohttp.web should upgrade to version 3.10.11 to receive a patch.

CVE-2025-14969 (GCVE-0-2025-14969)

Vulnerability from cvelistv5 – Published: 2026-01-26 19:36 – Updated: 2026-02-05 14:53

Title
Hibernate-reactive-core: hibernate reactive: denial of service due to connection leak on http client disconnect
Summary
A flaw was found in Hibernate Reactive. When an HTTP endpoint is exposed to perform database operations, a remote client can prematurely close the HTTP connection. This action may lead to leaking connections from the database connection pool, potentially causing a Denial of Service (DoS) by exhausting available database connections.

Mitigation ID: MIT-3

Phase: Requirements

Strategy: Language Selection

Description:

  • Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, languages such as Java, Ruby, and Lisp perform automatic garbage collection that releases memory for objects that have been deallocated.
Mitigation

Phase: Implementation

Description:

  • It is good practice to be responsible for freeing all resources you allocate and to be consistent with how and where you free resources in a function. If you allocate resources that you intend to free upon completion of the function, you must be sure to free the resources at all exit points for that function including error conditions.
Mitigation ID: MIT-47

Phases: Operation, Architecture and Design

Strategy: Resource Limitation

Description:

  • Use resource-limiting settings provided by the operating system or environment. For example, when managing system resources in POSIX, setrlimit() can be used to set limits for certain types of resources, and getrlimit() can determine how many resources are available. However, these functions are not available on all operating systems.
  • When the current levels get close to the maximum that is defined for the application (see CWE-770), then limit the allocation of further resources to privileged users; alternately, begin releasing resources for less-privileged users. While this mitigation may protect the system from attack, it will not necessarily stop attackers from adversely impacting other users.
  • Ensure that the application performs the appropriate error checks and error handling in case resources become unavailable (CWE-703).
CAPEC-469: HTTP DoS

An attacker performs flooding at the HTTP level to bring down only a particular web application rather than anything listening on a TCP/IP connection. This denial of service attack requires substantially fewer packets to be sent which makes DoS harder to detect. This is an equivalent of SYN flood in HTTP. The idea is to keep the HTTP session alive indefinitely and then repeat that hundreds of times. This attack targets resource depletion weaknesses in web server software. The web server will wait to attacker's responses on the initiated HTTP sessions while the connection threads are being exhausted.
