CVE-2025-58692 is an SQL Injection vulnerability identified in Fortinet's FortiVoice telephony product, specifically affecting versions 7.2.0 through 7.2.2 and 7.0.0 through 7.0.7. The flaw arises from improper neutralization of special elements in SQL commands, allowing an authenticated attacker to inject malicious SQL code via crafted HTTP or HTTPS requests. This injection can lead to unauthorized execution of code or commands on the underlying system, potentially enabling full control over the affected FortiVoice device. The vulnerability requires the attacker to have valid authentication credentials but does not require user interaction, and the attack complexity is low. The CVSS 3.1 base score is 7.7, indicating high severity with impacts on confidentiality, integrity, and availability. The vulnerability is exploitable remotely over the network, and the scope is unchanged, meaning the impact is confined to the vulnerable component. No public exploits or active exploitation have been reported yet, but the potential for damage is significant given FortiVoice's role in enterprise telephony infrastructure. FortiVoice devices often manage call routing, voicemail, and other critical communications functions, so compromise could disrupt business operations and expose sensitive communications data. The vulnerability was reserved in early September 2025 and published in November 2025, with no patch links currently available, indicating that organizations should prioritize monitoring and access controls until updates are released.

For European organizations, the impact of CVE-2025-58692 could be severe, particularly for enterprises and public sector entities relying on FortiVoice for telephony services. Successful exploitation could lead to unauthorized disclosure of sensitive communications, disruption of voice services, and potential lateral movement within networks. This could affect confidentiality by exposing call data and voicemail contents, integrity by allowing attackers to alter call routing or configurations, and availability by causing denial of service or system crashes. Critical infrastructure sectors such as government, finance, healthcare, and telecommunications that depend on FortiVoice for secure communications may face operational disruptions and data breaches. The attack requires authentication, so insider threats or compromised credentials increase risk. Given the remote network attack vector, exposed management interfaces accessible from the internet or poorly segmented internal networks elevate the threat. The absence of known exploits in the wild currently reduces immediate risk but does not diminish the urgency for mitigation, as attackers often develop exploits rapidly after vulnerability disclosure.

Organizations should immediately audit their FortiVoice deployments to identify affected versions (7.2.0 through 7.2.2 and 7.0.0 through 7.0.7). Until official patches are released by Fortinet, implement strict network segmentation and firewall rules to restrict access to FortiVoice management interfaces, allowing only trusted administrative IP addresses. Enforce strong authentication mechanisms, including multi-factor authentication (MFA), to reduce risk from compromised credentials. Monitor FortiVoice logs and network traffic for unusual or unauthorized SQL queries or command execution attempts. Disable any unnecessary services or interfaces on FortiVoice devices to minimize attack surface. Prepare to apply vendor patches promptly once available and test updates in a controlled environment before deployment. Conduct user training to prevent credential compromise and review incident response plans to address potential exploitation scenarios. Additionally, consider deploying web application firewalls (WAF) or intrusion prevention systems (IPS) capable of detecting and blocking SQL injection attempts targeting FortiVoice HTTP/HTTPS endpoints.
