The vulnerability, CVE-2025-49784, is an improper neutralization of special elements used in an SQL command, commonly known as SQL injection, affecting Fortinet FortiAnalyzer and FortiAnalyzer-BigData . This flaw resides in how the application handles specific user-controlled inputs. An authenticated attacker can exploit this by sending specially crafted requests to the affected device . Because the software fails to properly sanitize the input before incorporating it into an SQL query, the attacker can inject malicious SQL code. This injected code can manipulate the original query’s intent, potentially allowing the attacker to read, modify, or delete arbitrary data from the database, or in more severe scenarios, execute unauthorized code or commands on the underlying system .
Platform: Fortinet FortiAnalyzer
Version: 7.6.0-7.6.4, 7.4.0-7.4.7, 7.2 all, others
Vulnerability : SQL Injection
Severity: Medium (CVSS 5.6)
date: 2026-03-10
Prediction: Patch available (e.g., 7.6.5)
What Undercode Say:
Analytics:
The vulnerability CVE-2025-49784 is a classic SQL injection (CWE-89) requiring authentication, which lowers its exploitability score . The CVSS vector (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:L) confirms an attacker needs high privileges, but once exploited, it can lead to a total compromise of data confidentiality and some integrity and availability impacts . Given that Fortinet has already released patches for many branches (e.g., 7.6.5, 7.4.8, 7.6.1 for BigData), organizations still running unsupported or end-of-life versions (like 7.2 all versions) are at the highest risk and must upgrade or implement strict access controls immediately .
How Exploit:
A successful exploit would involve an authenticated user manipulating an input parameter that is later used in a database query. The following is a conceptual example of how the request might look, assuming the vulnerable parameter is `id` in a script named reports.
Conceptual Bash command using curl to exploit the SQL injection This attempts to retrieve all usernames and passwords from a 'users' table curl -X POST -k -H "Content-Type: application/x-www-form-urlencoded" \ -u "your_username:your_password" \ "https://<FortiAnalyzer-IP>/reports.php" \ -d "id=1 UNION SELECT username, password FROM users -- &report_type=summary"
A more direct approach if the vulnerability lies in a web interface:
-- Malicious SQL payload injected via a web form field
' OR '1'='1'; EXEC xp_cmdshell('whoami'); --
This payload attempts to log in as the first user (' OR '1'='1') and then execute a system command (whoami) if the database has high privileges.
Protection from this CVE:
- Immediate Patching: Upgrade to a fixed version as per Fortinet’s advisory. For FortiAnalyzer, upgrade to 7.6.5, 7.4.8, or later. For FortiAnalyzer-BigData, upgrade to 7.6.1 or 7.4.5 .
- Input Validation: As a defense-in-depth measure, ensure all user inputs are strictly validated and sanitized against an allowlist.
- Principle of Least Privilege: Ensure that database accounts used by the application have the minimum necessary permissions to reduce the impact of a successful SQL injection.
- Web Application Firewall (WAF): Deploy a WAF to help detect and block SQL injection attempts.
Impact:
Successful exploitation of this SQL injection vulnerability could allow an authenticated attacker to execute unauthorized code or commands . This could lead to a full system compromise, where the attacker gains control over the FortiAnalyzer appliance. Given FortiAnalyzer’s role in centralized logging and reporting, a breach could expose sensitive network logs, configurations, and credentials from multiple managed Fortinet devices, leading to a wider network intrusion.
