Title
Missing Certificate Validation in CleverControl Installer Allows Remote Code Execution
Summary
The CleverControl employee monitoring software (v11.5.1041.6) fails to validate TLS server certificates during the installation process. The installer downloads and executes external components using curl.exe --insecure, enabling a man-in-the-middle attacker to deliver malicious files that are executed with SYSTEM privileges. This can lead to full remote code execution with administrative rights. No patch is available as the vendor has been unresponsive. It is assumed that previous versions are also affected, but this is not confirmed.

Title
Improper TLS Certificate Validation RCE via Malicious Update in DeskTime Time Tracking App
Summary
Due to improper TLS certificate validation in the DeskTime Time Tracking App before version 1.3.674, attackers who can position themselves in the network path between the client and the DeskTime update servers can return a malicious executable in response to an update request. This allows the attacker to achieve user-level remote code execution on the affected client.

Title
Misconfigured certificate validation with self-signed certificates for Print Deploy
Summary
PaperCut Print Deploy is an optional component that integrates with PaperCut NG/MF which simplifies printer deployment and management. When the component is deployed to an environment, the customer has an option to configure the system to use a self-signed certificate. If the customer does not fully configure the system to leverage the trust database on the clients, it opens up the communication between clients and the server to man-in-the-middle attacks.
It was discovered that certain parts of the documentation related to the configuration of SSL in Print Deploy were lacking, which could potentially contribute to a misconfiguration of the Print Deploy client installation. PaperCut strongly recommends to use valid certificates to secure installations and to follow the updated documentation to ensure the correct SSL configuration. Those who use private CAs and/or self-signed certificates should make sure to copy their Certification Authority certificate, or their self signed certificate if using only one, to the trust store of their operating system and to the Java key store

CVE-2025-9708 (GCVE-0-2025-9708)

Title
Kubernetes C# Client: improper certificate validation in custom CA mode may lead to man-in-the-middle attacks
Summary
A vulnerability exists in the Kubernetes C# client where the certificate validation logic accepts properly constructed certificates from any Certificate Authority (CA) without properly verifying the trust chain. This flaw allows a malicious actor to present a forged certificate and potentially intercept or manipulate communication with the Kubernetes API server, leading to possible man-in-the-middle attacks and API impersonation.

Title
Insufficient Certificate Validation in Multiple Mobile Applications Allows Man in the Middle Interception
Summary
A vulnerability in the certificate validation logic may allow applications to accept untrusted or improperly validated server identities during TLS communication. An attacker in a privileged network position may be able to intercept or modify traffic if they can position themselves within the communication channel. Successful exploitation may compromise confidentiality, integrity, and availability of application data.

Title
Improper Certificate Validation in TP-Link Omada Cloud Communications
Summary
A
certification validation weakness exists in communication between affected
Omada devices and cloud controllers. Certificate identity verification does not
adequately validate that a presented certificate corresponds to the expected
cloud controller hostname, which may allow certificate validation protections
to be bypassed under specific conditions.
Successful
exploitation may allow interception or modification of communication between
affected devices and cloud controllers.

Mitigation
Architecture and Design
Implementation
Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
Mitigation
Implementation
If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
CAPEC-459: Creating a Rogue Certification Authority Certificate
An adversary exploits a weakness resulting from using a hashing algorithm with weak collision resistance to generate certificate signing requests (CSR) that contain collision blocks in their "to be signed" parts. The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.
CAPEC-475: Signature Spoofing by Improper Validation
An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.
