Vulnerability from github – Published: 2022-05-07 00:00 – Updated: 2022-05-07 00:00
VLAI
Details

In multiple Tecson Tankspion and GOKs SmartBox 4 products the affected application doesn't properly restrict access to an endpoint that is responsible for saving settings, to a unauthenticated user with limited access rights. Based on the lack of adequately implemented access-control rules, by accessing a specific uniform resource locator (URL) on the web server, a malicious user is able to change the application settings without authenticating at all, which violates originally laid ACL rules.

Details

Incorrect authentication of application WebSocket connections in Loom Desktop for Mac up to 0.16.0 allows remote code execution from either malicious JavaScript in a browser or hosts on the same network, during periods in which a user is recording a video with the application. The same attack vector can be used to crash the application at any time.

Vulnerability from github – Published: 2026-01-20 03:30 – Updated: 2026-01-20 03:30
VLAI
Details

A weakness has been identified in CRMEB up to 5.6.3. The impacted element is the function remoteRegister of the file crmeb/app/services/user/LoginServices.php of the component JSON Token Handler. Executing a manipulation of the argument uid can lead to improper authentication. The attack may be performed from remote. The attack requires a high level of complexity. The exploitability is regarded as difficult. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

Vulnerability from github – Published: 2025-12-17 15:34 – Updated: 2025-12-17 15:34
VLAI
Details

A vulnerability in the application software of multiple Radiometer products may allow remote code execution and unauthorized device management when specific internal conditions are met. Exploitation requires that a remote connection is established with additional information obtained through other means. The issue is caused by a weakness in the analyzer’s application software.                                                                                                                                                                                                Other related CVE's are CVE-2025-14095 & CVE-2025-14096.                                                                                                      Affected customers have been informed about this vulnerability. This CVE is being published to provide transparency.

Required Configuration for Exposure: Affected application software version is in use and remote support feature is enabled in the analyzer.                                                                                                                                                                        Temporary work Around: If the network is not considered secure, please remove the analyzer from the network.                         Permanent solution: Customers should ensure the following: • The network is secure, and access follows best practices. Local Radiometer representatives will contact all affected customers to discuss a permanent solution.                                                      Exploit Status:

Researchers have provided working proof-of-concept (PoC). Radiometer is not aware of any publicly available exploits at the time of this publication.

Mitigation
Architecture and Design

Strategy: Libraries or Frameworks

Use an authentication framework or library such as the OWASP ESAPI Authentication feature.

CAPEC-114: Authentication Abuse

An attacker obtains unauthorized access to an application, service or device either through knowledge of the inherent weaknesses of an authentication mechanism, or by exploiting a flaw in the authentication scheme's implementation. In such an attack an authentication mechanism is functioning but a carefully controlled sequence of events causes the mechanism to grant access to the attacker.

CAPEC-115: Authentication Bypass

An attacker gains access to application, service, or device with the privileges of an authorized or privileged user by evading or circumventing an authentication mechanism. The attacker is therefore able to access protected data without authentication ever having taken place.

CAPEC-151: Identity Spoofing

Identity Spoofing refers to the action of assuming (i.e., taking on) the identity of some other entity (human or non-human) and then using that identity to accomplish a goal. An adversary may craft messages that appear to come from a different principle or use stolen / spoofed authentication credentials.

CAPEC-194: Fake the Source of Data

An adversary takes advantage of improper authentication to provide data or services under a falsified identity. The purpose of using the falsified identity may be to prevent traceability of the provided data or to assume the rights granted to another individual. One of the simplest forms of this attack would be the creation of an email message with a modified "From" field in order to appear that the message was sent from someone other than the actual sender. The root of the attack (in this case the email system) fails to properly authenticate the source and this results in the reader incorrectly performing the instructed action. Results of the attack vary depending on the details of the attack, but common results include privilege escalation, obfuscation of other attacks, and data corruption/manipulation.

CAPEC-22: Exploiting Trust in Client

An attack of this type exploits vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by communicating directly with the server where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.

CAPEC-57: Utilizing REST's Trust in the System Resource to Obtain Sensitive Data

This attack utilizes a REST(REpresentational State Transfer)-style applications' trust in the system resources and environment to obtain sensitive data once SSL is terminated.

CAPEC-593: Session Hijacking

This type of attack involves an adversary that exploits weaknesses in an application's use of sessions in performing authentication. The adversary is able to steal or manipulate an active session and use it to gain unathorized access to the application.

CAPEC-633: Token Impersonation

An adversary exploits a weakness in authentication to create an access token (or equivalent) that impersonates a different entity, and then associates a process/thread to that that impersonated token. This action causes a downstream user to make a decision or take action that is based on the assumed identity, and not the response that blocks the adversary.

CAPEC-650: Upload a Web Shell to a Web Server

By exploiting insufficient permissions, it is possible to upload a web shell to a web server in such a way that it can be executed remotely. This shell can have various capabilities, thereby acting as a "gateway" to the underlying web server. The shell might execute at the higher permission level of the web server, providing the ability the execute malicious code at elevated levels.

CAPEC-94: Adversary in the Middle (AiTM)

An adversary targets the communication between two components (typically client and server), in order to alter or obtain data from transactions. A general approach entails the adversary placing themself within the communication channel between the two components.
