CVE-2024-48889
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability [CWE-78] in FortiManager version 7.6.0, version 7.4.4 and below, version 7.2.7 and below, version 7.0.12 and below, version 6.4.14 and below and FortiManager Cloud version 7.4.4 and below, version 7.2.7 to 7.2.1, version 7.0.12 to 7.0.1 may allow an authenticated remote attacker to execute unauthorized code via FGFM crafted requests.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceOS Command Injection vulnerability in FortiManager's FGFM (FortiGate Management) protocol handler allows an authenticated remote attacker to execute unauthorized operating system commands via specially crafted FGFM requests. The vulnerability stems from improper neutralization of special elements in user-supplied input that gets passed to system shell commands.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify FortiManager product typeDetermine if the system is FortiManager (on-premises) or FortiManager Cloud. This can be done via the web UI under System > Settings or via CLI command 'get system status' which shows the product name.Affected if The product is FortiManager or FortiManager Cloud
-
Check installed FortiManager versionRun 'get system status' in the FortiManager CLI or check the firmware version in the web UI under Dashboard > System Information widget. Note the exact version number.Affected if The version falls within any of these ranges: FortiManager >=6.4.10 and <6.4.15, >=7.0.5 and <7.0.13, >=7.2.3 and <7.2.8, >=7.4.0 and <7.4.5, or equals 7.6.0. FortiManager Cloud >=7.0.1 and <7.0.13, >=7.2.1 and <7.2.8, or >=7.4.1 and <7.4.5.
-
Verify FGFM protocol is enabledIn FortiManager CLI, run 'get system interface' to list interfaces and their settings. Check if the FGFM daemon is enabled by reviewing the management interface configuration. Alternatively, check if port 541 (FGFM default) is listening using 'diag netstat -an | grep 541'.Affected if FGFM protocol is enabled and port 541 is open/listening on the management interface
-
Assess FGFM network exposureReview firewall policies and interface access settings to determine if FGFM port 541 is accessible from untrusted networks. Check the 'set allowaccess' settings on management interfaces in the configuration. Use 'show system interface' to review all interface access permissions.Affected if FGFM (port 541) is accessible from interfaces or networks that are not limited to trusted management IPs
You are affected if you run FortiManager or FortiManager Cloud with a version in the affected ranges AND the FGFM protocol is enabled and accessible, particularly from networks outside your trusted management infrastructure.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped6.4.157.0.137.2.8
Upgrade FortiManager to vendor-specified patched versions. For systems that cannot be immediately upgraded, restrict FGFM access to trusted management networks and monitor for suspicious FGFM traffic patterns.
FortiManager: upgrade to 6.4.15, 7.0.13, 7.2.8, 7.4.5, or 7.6.0 | FortiManager Cloud: upgrade to 7.0.13, 7.2.8, or 7.4.5
- Identify your current FortiManager or FortiManager Cloud version using the Web UI (System > Settings > System Information) or CLI: `get system status`
- Review the FortiManager Upgrade Path matrix at docs.fortinet.com to ensure your current version can upgrade directly to a fixed version
- Plan maintenance window as upgrades require system downtime
- Backup current FortiManager configuration via: `execute backup full-config` to FTP/TFTP/SCP or use Web UI: System Settings > Maintenance > Backup & Restore
- For FortiManager on-premises: Download the firmware for your target version (6.4.15, 7.0.13, 7.2.8, 7.4.5, or 7.6.0) from support.fortinet.com
- For FortiManager Cloud: Use the Cloud portal or contact Fortinet support for upgrade to 7.0.13, 7.2.8, or 7.4.5
- Upload firmware via Web UI: System Settings > Firmware > Upload, or CLI: `execute restore firmware <protocol> <server> <file>`
- Reboot the system after firmware installation completes
