CVE-2025-58692: Fortinet FortiVoice SQLi Vulnerability

CVE-2025-58692 Overview

CVE-2025-58692 is an SQL Injection vulnerability [CWE-89] affecting Fortinet FortiVoice. The flaw stems from improper neutralization of special elements used in SQL commands within the FortiVoice web management interface. An authenticated attacker can send specifically crafted HTTP or HTTPS requests to execute unauthorized code or commands on the underlying system.

The vulnerability impacts FortiVoice versions 7.2.0 through 7.2.2 and 7.0.0 through 7.0.7. Fortinet published the advisory FG-IR-25-666 documenting the issue and providing patched versions.

Critical Impact
Authenticated attackers can execute unauthorized code or commands on FortiVoice systems through crafted HTTP/HTTPS requests, compromising confidentiality, integrity, and availability of voice communication infrastructure.

Affected Products

Fortinet FortiVoice 7.2.0 through 7.2.2
Fortinet FortiVoice 7.0.0 through 7.0.7
FortiVoice web management interface (HTTP/HTTPS request handlers)

Technical Details for CVE-2025-58692

Vulnerability Analysis

The vulnerability is classified as SQL Injection under [CWE-89]. FortiVoice fails to properly neutralize special characters in user-supplied input before incorporating that input into SQL statements. The result is that an attacker can break out of the intended query context and inject arbitrary SQL syntax.

FortiVoice is a unified communications platform handling voice, conferencing, and messaging services. Successful exploitation gives the attacker the ability to execute unauthorized code or commands, which extends the impact beyond simple data disclosure into full system compromise.

The attack is network-accessible and requires low privileges. An attacker needs valid authentication to the FortiVoice management interface but does not require administrator-level access or user interaction.

Root Cause

The root cause is the absence of parameterized queries or proper input sanitization in HTTP and HTTPS request handlers within the FortiVoice management interface. User-controlled parameters are concatenated directly into SQL statements, allowing attacker-supplied syntax to be interpreted by the database engine.

Attack Vector

The attack vector is network-based and requires authentication. An attacker authenticates to the FortiVoice web management interface, then submits crafted HTTP or HTTPS requests containing malicious SQL payloads in vulnerable parameters. The injected SQL leverages stored procedures or database functionality to escalate from query execution to command execution on the host. No verified public exploit code is available at this time. Refer to the Fortinet Security Advisory FG-IR-25-666 for technical details.

Detection Methods for CVE-2025-58692

Indicators of Compromise

Unexpected authenticated sessions to the FortiVoice management interface from unusual source IPs or geolocations.
HTTP/HTTPS requests containing SQL metacharacters such as single quotes, UNION SELECT, --, or stacked queries against FortiVoice endpoints.
Unexplained database errors, slow query responses, or new administrative accounts on the FortiVoice appliance.
Outbound connections from FortiVoice to unknown external hosts following authenticated sessions.

Detection Strategies

Inspect web server and application logs on FortiVoice for parameter values containing SQL syntax patterns.
Deploy WAF or IPS signatures that identify SQL injection payloads targeting FortiVoice management URIs.
Correlate authentication events with subsequent administrative configuration changes or command execution artifacts.

Monitoring Recommendations

Forward FortiVoice authentication, configuration, and HTTP access logs to a centralized SIEM for correlation.
Alert on any successful authentication followed by anomalous database query patterns or shell command execution.
Monitor for the creation of new local accounts, SSH keys, or scheduled tasks on FortiVoice appliances.

How to Mitigate CVE-2025-58692

Immediate Actions Required

Upgrade FortiVoice to a fixed release as specified in the Fortinet Security Advisory FG-IR-25-666.
Restrict access to the FortiVoice management interface to trusted administrative networks only.
Audit existing FortiVoice user accounts and rotate credentials for any account with management access.
Review logs from before the patch date for evidence of exploitation attempts.

Patch Information

Fortinet released fixed versions of FortiVoice addressing CVE-2025-58692. Administrators running FortiVoice 7.2.0 through 7.2.2 or 7.0.0 through 7.0.7 must upgrade to a remediated build per the vendor advisory FG-IR-25-666. Consult the Fortinet PSIRT advisory for specific target versions and upgrade paths.

Workarounds

Limit network exposure of the FortiVoice management interface using firewall ACLs and management VLAN segregation.
Enforce multi-factor authentication for all FortiVoice administrative accounts to raise the bar for credential abuse.
Disable or restrict accounts that do not require web management access until patches are applied.

bash

# Configuration example - restrict management access on upstream firewall
# Allow only the trusted admin subnet to reach FortiVoice management ports
iptables -A FORWARD -s 10.10.50.0/24 -d <fortivoice_ip> -p tcp --dport 443 -j ACCEPT
iptables -A FORWARD -d <fortivoice_ip> -p tcp --dport 443 -j DROP
iptables -A FORWARD -d <fortivoice_ip> -p tcp --dport 80 -j DROP
