Critical Vulnerabilities Discovered

Recent discoveries have highlighted significant vulnerabilities in these products, prompting immediate action to safeguard networks.

1. OS Command Injection in FortiManager (CVE-2024-48889)

Overview: A critical OS Command Injection vulnerability (CVE-2024-48889) exists in FortiManager, potentially allowing an authenticated attacker to execute unauthorized code. The vulnerability is exploited via carefully crafted FGFM (Fortinet’s secure communication protocol) requests. Affected Products and Versions: The vulnerability impacts the following versions of FortiManager:

  • FortiManager 7.6: Prior to version 7.6.1
  • FortiManager 7.4: Prior to version 7.4.5
  • FortiManager 7.2: Prior to version 7.2.8
  • FortiManager 7.0: Prior to version 7.0.13
  • FortiManager 6.4: Prior to version 6.4.15

Additionally, certain legacy FortiAnalyzer models, including 1000E, 3000F, and 3700G, are at risk if configured with specific global settings:

Severity: This vulnerability has been assigned a CVSSv3 score of 9.6, classifying it as “Critical.” Successful exploitation could result in full system compromise. Mitigation Steps: Fortinet recommends upgrading to the latest versions to mitigate the risk:

  • FortiManager 7.6.1 or newer
  • FortiManager 7.4.5 or newer
  • FortiManager 7.2.8 or newer
  • FortiManager 7.0.13 or newer
  • FortiManager 6.4.15 or newer

2. Path Traversal Vulnerability in FortiWLM (CVE-2023-34990)

Overview: FortiWLM has a path traversal vulnerability (CVE-2023-34990) that allows unauthenticated attackers to access sensitive files via relative path traversal. Exploitation of this vulnerability could lead to data leakage and compromise network security. Affected Products and Versions:

  • FortiWLM 8.6.0 through 8.6.5
  • FortiWLM 8.5.0 through 8.5.4

Severity: This issue has a CVSSv3 score of 9.6, making it highly critical due to its potential for widespread exploitation. Mitigation Steps: Fortinet has released patches to address this flaw. Users are urged to update to the following versions:

  • FortiWLM 8.6.6 or newer
  • FortiWLM 8.5.5 or newer

Actionable Recommendations

To address the vulnerabilities and secure your systems, Fortinet has provided actionable guidance:

  1. Patch Systems Immediately:
    • Upgrade FortiManager and FortiWLM devices to the patched versions outlined above.
  2. Audit Device Configurations:
    • Examine system configurations to identify legacy settings that could increase exposure to threats.
  3. Monitor Network Activity:
    • Implement monitoring tools to detect unusual behavior, such as anomalous FGFM requests or suspicious file access attempts.
  4. Adopt Robust Security Protocols:
    • Use multi-factor authentication (MFA) and enforce least-privilege access policies across systems to limit potential attack vectors.
