One Voice Operations Center: Use of Hard-coded Cryptographic Key
CVE-2024-52881 is a high-severity use of hard-coded cryptographic key vulnerability in One Voice Operations Center from AudioCodes, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 8.4.582 as the first without the flaw, so updating One Voice Operations Center to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.36% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update One Voice Operations Center to 8.4.582 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
