Vulnerability from github – Published: 2025-12-02 00:36 – Updated: 2025-12-02 00:36DOS on the admin panel
Severity Rating: Medium
Vector: Denial Of Service
CVE: XXX
CWE: 400 - Uncontrolled Resource Consumption
CVSS Score: 4.9
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H
Analysis
A Denial of Service (DoS) vulnerability has been identified in the application related to the handling of scheduled_at parameters. Specifically, the application fails to properly sanitize input for cron expressions. By manipulating the scheduled_at parameter with a malicious input, such as a single quote, the application admin panel becomes non-functional, causing significant disruptions to administrative operations.
The only way to recover from this issue is to manually access the host server and modify the backup.yaml file to correct the corrupted cron expression
Proof of Concept
1) Change the value of scheduled_at parameter to ' as shown in the following figures at the http://127.0.0.1/admin/tools endpoint, and observe the response in the second figure:
Figure: Http request on tool endpoint
Figure: Http response on tool endpoint
2) When trying to access the admin panel, the panel is broken as shown in the following figure. Additionally, the value change is reflected in the backup.yaml file, as shown in the second figure:
Figure: Error message view
Figure: Backup.yaml file
Workarounds
No workaround is currently known

Specifically, the application fails to properly sanitize input for cron expressions. By manipulating the `scheduled_at` parameter with a malicious input, such as a single quote, the application admin panel becomes non-functional, causing significant disruptions to administrative operations.\n\nThe only way to recover from this issue is to manually access the host server and modify the `backup.yaml` file to correct the corrupted cron expression\n\n## Proof of Concept\n\n1) Change the value of `scheduled_at` parameter to `\u0027` as shown in the following figures at the `http://127.0.0.1/admin/tools` endpoint, and observe the response in the second figure:\n \n *Figure: Http request on tool endpoint*\n\n *Figure: Http response on tool endpoint*\n\n2) When trying to access the admin panel, the panel is broken as shown in the following figure. Additionally, the value change is reflected in the `backup.yaml` file, as shown in the second figure:\n \n *Figure: Error message view*\n\n *Figure: Backup.yaml file*\n\n\n## Workarounds\nNo workaround is currently known\n\n# Timeline\n**2024-07-24** Issue identified\n\n**2024-09-27** Vendor contacted\n\n\n# About X41 D-Sec GmbH\nX41 is an expert provider for application security services.\nHaving extensive industry experience and expertise in the area of information\nsecurity, a strong core security team of world class security experts enables\nX41 to perform premium security services.\n\nFields of expertise in the area of application security are security centered\ncode reviews, binary reverse engineering and vulnerability discovery.\nCustom research and IT security consulting and support services are core\ncompetencies of X41.",

GHSA-X67R-8JFC-3R5M
Vulnerability from github – Published: 2023-10-04 18:30 – Updated: 2024-01-25 18:30A vulnerability in an API endpoint of multiple Cisco Unified Communications Products could allow an unauthenticated, remote attacker to cause high CPU utilization, which could impact access to the web-based management interface and cause delays with call processing. This API is not used for device management and is unlikely to be used in normal operations of the device.
This vulnerability is due to improper API authentication and incomplete validation of the API request. An attacker could exploit this vulnerability by sending a crafted HTTP request to a specific API on the device. A successful exploit could allow the attacker to cause a denial of service (DoS) condition due to high CPU utilization, which could negatively impact user traffic and management access. When the attack stops, the device will recover without manual intervention.

Mitigation
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place. The login application should be protected against DoS attacks as much as possible. Limiting the database access, perhaps by caching result sets, can help minimize the resources expended. To further limit the potential for a DoS attack, consider tracking the rate of requests received from users and blocking requests that exceed a defined rate threshold.
Mitigation
- Mitigation of resource exhaustion attacks requires that the target system either:
- The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
- The second solution is simply difficult to effectively institute -- and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
- recognizes the attack and denies that user further access for a given amount of time, or
- uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Mitigation
Ensure that protocols have specific limits of scale placed on them.
Mitigation
Ensure that all failures in resource allocation place the system into a safe posture.
CAPEC-147: XML Ping of the Death
An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.
CAPEC-227: Sustained Client Engagement
An adversary attempts to deny legitimate users access to a resource by continually engaging a specific resource in an attempt to keep the resource tied up as long as possible. The adversary's primary goal is not to crash or flood the target, which would alert defenders; rather it is to repeatedly perform actions or abuse algorithmic flaws such that a given resource is tied up and not available to a legitimate user. By carefully crafting a requests that keep the resource engaged through what is seemingly benign requests, legitimate users are limited or completely denied access to the resource.
CAPEC-492: Regular Expression Exponential Blowup
An adversary may execute an attack on a program that uses a poor Regular Expression(Regex) implementation by choosing input that results in an extreme situation for the Regex. A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.
