Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-52881 is a cryptographic failure vulnerability (CWE-321) in AudioCodes One Voice Operations Center (OVOC) versions before 8.4.582. The issue stems from the use of a hard-coded key, which enables decryption of sensitive data, such as passwords, extracted from the topology file. The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), highlighting high confidentiality impact with network accessibility and no requirements for privileges or user interaction.
An unauthenticated attacker with network access can exploit this vulnerability if they obtain the topology file. By leveraging the hard-coded key, the attacker can decrypt embedded sensitive information, including passwords, potentially leading to unauthorized access to managed voice systems or further compromise within the environment.
For mitigation details, refer to the SYSS advisory at https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2024-079.txt and the AudioCodes OVOC product page at https://www.audiocodes.com/solutions-products/products/management-products-solutions/one-voice-operations-center. Updating to OVOC version 8.4.582 or later addresses the hard-coded key issue.

Mitigating Controls (NIST 800-53 r5) AI
Requiring cryptographic keys to be established and managed according to defined requirements prevents developers from embedding static unchangeable keys.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure-SDLC activities such as code review and secret scanning directly prevent embedding static keys.
Data-at-rest protection policies require proper key management and therefore discourage hard-coded keys.
Data-in-transit protection similarly depends on non-hard-coded keys for encryption.
Configuration baselines and reviews can prohibit hard-coded keys in deployed artifacts.

Key-management controls that govern generation, rotation and protection of keys make the use of embedded hard-coded cryptographic keys less likely and easier to detect.
