Security readout for executives and security teams
Plain-English summary
AudioCodes 405HD VoIP phones running firmware 2.2.12 had cross-site scripting weaknesses in the web interface. An attacker could inject JavaScript through phone book entries or domain-name data sent to the device, potentially affecting users who manage or view the device interface.
Executive priority
Treat this as a targeted device-management risk, not a confirmed widespread emergency. Prioritize inventory and vendor guidance because the affected firmware is specific and the source bundle lacks patch, CVSS, and exploitation evidence.
Technical view
The CVE describes XSS in multiple input fields of AudioCodes 405HD firmware 2.2.12, including the domain field and personal settings. The reported injection vectors are manipulated phone book entries and domain names supplied through the domain controller. No CVSS, CWE, patch status, or broader version range is provided in the bundle.
Likely exposure
Exposure is most likely where AudioCodes 405HD phones on firmware 2.2.12 are deployed and their web interface, phone book, or domain-controller-fed configuration paths are reachable by local users or remote systems.
Exploitation context
The source says local or remote attackers can inject JavaScript into the device web interface through specific input sources. CISA KEV is false in the bundle, and no cited source here confirms active exploitation.
Researcher notes
Evidence is limited to the CVE description and Fraunhofer advisory reference. The affected product is AudioCodes 405HD firmware 2.2.12 only as stated. Do not assume other AudioCodes models, versions, exploit availability, or remediation specifics without vendor confirmation.
Mitigation direction
- Identify whether AudioCodes 405HD firmware 2.2.12 exists in the environment.
- Check AudioCodes support or advisory guidance for fixed firmware or vendor mitigations.
- Restrict device web management access to trusted administrative networks.
- Limit untrusted changes to phone book and domain-controller-provided values.
- Monitor device administration sessions for unexpected script behavior or UI tampering.
Validation and detection
- Inventory 405HD phones and record firmware versions.
- Confirm whether device web interfaces are reachable from user or remote networks.
- Review phone book and domain-controller integration paths for untrusted input sources.
- Check vendor documentation for updated firmware or configuration hardening.
- Document any compensating controls when firmware status cannot be confirmed.
