CVE-2018-5757: An issue was discovered on AudioCodes 450HD IP Phone devices with firmware 3.0.0.535.106.

An issue was discovered on AudioCodes 450HD IP Phone devices with firmware 3.0.0.535.106. The traceroute and ping functionality, which uses a parameter in a request to command.cgi from the Monitoring page in the web UI, unsafely puts user-alterable data directly into an OS command, leading to Remote Code Execution via shell metacharacters in the query string.

Security readout for executives and security teams

Plain-English summary

CVE-2018-5757 is a command injection issue in the web interface of AudioCodes 450HD IP phones. The phone’s ping and traceroute tools can pass user-controlled input into operating system commands, allowing remote code execution if the vulnerable interface is reachable. Sources identify firmware 3.0.0.535.106; broader impact and official fix details are not provided.

Executive priority

Treat this as a high-priority network device exposure review, especially for voice networks reachable from user segments. Remote code execution on phones can support persistence, monitoring disruption, or internal pivoting. Urgency depends on whether vulnerable firmware and reachable web management interfaces exist in your environment.

Technical view

The web UI Monitoring page exposes traceroute and ping through command.cgi. A user-controlled request parameter is inserted directly into an OS command. Shell metacharacters in the query string can alter command execution, resulting in remote code execution on the phone. The source identifies AudioCodes 450HD firmware 3.0.0.535.106 only; broader version impact is not established.

Likely exposure

Exposure is most likely where AudioCodes 450HD phones running firmware 3.0.0.535.106 have their management web UI reachable from untrusted networks or users. The bundle does not confirm whether authentication is required, whether other models are affected, or whether later firmware versions are fixed.

Exploitation context

The CVE describes remote code execution through web UI parameters and cites a public Rhino Security Labs CVE page. The source bundle does not show CISA KEV listing, active exploitation, exploit prevalence, CVSS scoring, or vendor remediation details.

Researcher notes

Evidence is narrow but clear for AudioCodes 450HD firmware 3.0.0.535.106. The affected-product metadata in the bundle is incomplete, and no CWE, CVSS, patch, or authentication context is supplied. Validate model, firmware, and management-plane reachability before assigning enterprise risk.

Mitigation direction

  • Inventory AudioCodes 450HD phones and record firmware versions.
  • Check AudioCodes guidance for fixed firmware or replacement direction.
  • Restrict phone web management access to trusted admin networks or VPN.
  • Block untrusted access to command.cgi and Monitoring functions where feasible.
  • Monitor for suspicious command.cgi requests using ping or traceroute parameters.

Validation and detection

  • Confirm whether any 450HD devices run firmware 3.0.0.535.106.
  • Review network paths to the phone web UI from user and external segments.
  • Check web or proxy logs for unusual command.cgi Monitoring requests.
  • Verify updated firmware status against official AudioCodes guidance.
  • Confirm management interfaces are not reachable from untrusted networks.
