CVE-2025-24525 is a high-severity vulnerability affecting the Keysight Ixia Vision product family, specifically version 6.3.1. The core issue is the presence of hardcoded cryptographic material within the device's software, classified under CWE-321 (Use of Hard-coded Cryptographic Key). This vulnerability arises because the device ships with a default TLS certificate that is not unique per installation. If the end user does not replace this default certificate, an attacker can exploit the hardcoded cryptographic material to intercept or decrypt sensitive payloads transmitted to the device via API calls or during user authentication processes. The vulnerability allows a remote attacker to perform a man-in-the-middle (MitM) attack without requiring any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact is limited to confidentiality, with no direct effect on integrity or availability. The vendor has addressed this vulnerability in version 6.9.1, released on September 23, 2025, recommending users upgrade and replace the default TLS certificates to mitigate the risk. No known exploits are currently reported in the wild, but the ease of exploitation and the critical nature of the cryptographic flaw warrant immediate attention.

For European organizations using the Keysight Ixia Vision product family, this vulnerability poses a significant risk to the confidentiality of sensitive network monitoring and testing data. Ixia Vision devices are often deployed in network infrastructure environments for traffic analysis, security testing, and performance monitoring. An attacker exploiting this vulnerability could intercept API communications and authentication credentials, potentially gaining unauthorized access to network management functions or sensitive operational data. This could lead to broader network reconnaissance or facilitate subsequent attacks. Given the high reliance on secure network operations in critical sectors such as telecommunications, finance, and government within Europe, the exposure of cryptographic keys undermines trust in network security controls and could result in data breaches or compliance violations under regulations like GDPR. The lack of integrity or availability impact reduces the risk of direct service disruption but does not diminish the severity of confidential data exposure.

European organizations should immediately verify the version of their Keysight Ixia Vision devices and upgrade to version 6.9.1 or later where the vulnerability is patched. It is critical to replace the default TLS certificates shipped with the devices with unique, organization-specific certificates issued by a trusted certificate authority. Network administrators should audit existing deployments to ensure no devices are operating with default cryptographic material. Additionally, monitoring network traffic for unusual API call patterns or unexpected TLS certificate usage can help detect exploitation attempts. Implementing network segmentation to isolate management interfaces of Ixia Vision devices can limit exposure. Organizations should also review and tighten access controls around these devices and ensure that any API endpoints are protected by additional authentication layers where possible. Regular vulnerability scanning and penetration testing focused on cryptographic configurations can help identify residual risks.
