CVE-2025-43483 is a security vulnerability identified in HP Inc.'s Poly Clariti Manager software, specifically in versions prior to 10.12.1. The vulnerability is classified under CWE-321, which pertains to the use of hard-coded cryptographic keys within software. In this case, the Poly Clariti Manager contains embedded cryptographic keys that are hard-coded into the application code or configuration, making them retrievable by an attacker with access to the system or software binaries. Hard-coded keys undermine the security of cryptographic operations because they cannot be changed easily and if discovered, allow attackers to decrypt sensitive data or impersonate legitimate components. The vulnerability has a CVSS 4.0 base score of 5.9, indicating a medium severity level. The vector details show that the attack requires local or adjacent network access (AV:A), low attack complexity (AC:L), privileges (PR:L), and partial authentication (AT:P), but no user interaction (UI:N). The impact is primarily on confidentiality (VC:H), with no impact on integrity or availability. The scope is limited (SC:L), and there are no known exploits in the wild at the time of publication. HP has addressed this issue in the latest software update (version 10.12.1 and later), recommending users upgrade to mitigate the risk. The vulnerability could allow an attacker with some level of access to extract the hard-coded cryptographic keys, potentially enabling decryption of sensitive communications or data managed by the Poly Clariti Manager, which is used for managing unified communications and collaboration devices and services.

For European organizations using HP Poly Clariti Manager, this vulnerability poses a moderate risk to the confidentiality of communications and data managed by the platform. Since the cryptographic keys are hard-coded, an attacker who gains local or adjacent network access with limited privileges could extract these keys and decrypt sensitive information or impersonate devices or services within the managed environment. This could lead to unauthorized disclosure of corporate communications, intellectual property, or personal data, potentially violating GDPR requirements. The impact is particularly significant for sectors relying heavily on secure unified communications, such as finance, healthcare, government, and critical infrastructure. Although the vulnerability does not directly affect integrity or availability, the confidentiality breach alone can have severe reputational and regulatory consequences. The absence of known exploits reduces immediate risk, but the medium CVSS score and ease of key extraction warrant prompt remediation. Organizations with remote or hybrid workforces using Poly Clariti Manager should be especially vigilant, as attackers could leverage network adjacency to exploit this flaw.

European organizations should immediately verify their Poly Clariti Manager version and upgrade to version 10.12.1 or later where HP has patched the hard-coded key vulnerability. Beyond patching, organizations should conduct a thorough audit of their unified communications environment to detect any unauthorized access or suspicious activity that might indicate key extraction attempts. Implement network segmentation to limit access to the Poly Clariti Manager systems, restricting local and adjacent network access to trusted administrators only. Employ strong access controls and multi-factor authentication for all administrative accounts to reduce the risk of privilege escalation. Additionally, consider deploying endpoint detection and response (EDR) solutions to monitor for attempts to extract or misuse cryptographic keys. Regularly review and update cryptographic key management policies to avoid hard-coded keys in any custom or third-party integrations. Finally, ensure that incident response plans include scenarios for cryptographic key compromise to enable rapid containment and recovery.
