GHSA-M3CR-3Q92-CG98
Vulnerability from github – Published: 2026-08-20 00:35 – Updated: 2026-08-20 00:35In Splunk SOAR versions below 8.6.0, an unauthenticated user who can observe or alter network traffic between Splunk SOAR and a configured CyberArk Representational State Transfer (REST) server could access or modify all relevant data exchanged through that credential manager. The vulnerability is possible because the CyberArk REST client does not verify server certificates by default. The attack requires the attacker to have network-path interception capability between Splunk SOAR and the configured CyberArk REST server. For more information see Manage your organization's credentials with a password vault (https://help.splunk.com/en/splunk-soar/soar-cloud/administer-soar-cloud/configure-administration-settings-in-splunk-soar-cloud/manage-your-organizations-credentials-with-a-password-vault) in the Splunk documentation.

GHSA-M562-W2V4-CHP8
Vulnerability from github – Published: 2023-07-11 09:30 – Updated: 2024-09-30 12:30DroneScout ds230 Remote ID receiver from BlueMark Innovations is affected by an Improper Authentication vulnerability during the firmware update procedure.
Specifically, the firmware update procedure ignores and does not check the validity of the TLS certificate of the HTTPS endpoint from which the firmware update package (.tar.bz2 file) is downloaded. An attacker with the ability to put himself in a Man-in-the-Middle situation (e.g., DNS poisoning, ARP poisoning, control of a node on the route to the endpoint, etc.) can trick the DroneScout ds230 to install a crafted malicious firmware update containing arbitrary files (e.g., executable and configuration) and gain administrative (root) privileges on the underlying Linux operating system. This issue affects DroneScout ds230 firmware from version 20211210-1627 through 20230329-1042.

Mitigation
Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
Mitigation
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.
