Impact

An authenticated remote code execution vulnerability exists in the BIG‑IP and BIG‑IQ Configuration utility, allowing an attacker who can authenticate to the system to execute arbitrary code, potentially compromising confidentiality, integrity, and availability of the device. This weakness is classified as CWE‑502, indicating a flaw in binary input handling that can be abused to inject malicious code. The description explicitly states the vulnerability is exploitable through undisclosed vectors, implying the exact attack path is not publicly known but is available to those with valid credentials.

Affected Systems

This vulnerability impact F5 BIG‑IP and BIG‑IQ devices. No specific software versions are listed, and any versions that have reached End of Technical Support are not evaluated. Administrators should verify the current firmware or software revision on their managed devices to determine applicability.

Risk and Exploitability

The CVSS score of 8.7 classifies this issue as high severity. Although the EPSS score is not available, the lack of listing in the CISA KEV catalog does not diminish the threat of an authenticated attacker obtaining remote code execution via the configuration utility. The exploit would require valid credentials and access to the configuration interface, suggesting that strong authentication controls, network segmentation, and timely patching are critical to mitigate this risk.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the latest F5 patches or upgrade to a supported BIG‑IP or BIG‑IQ version that removes the binary input handling flaw.
  • Limit access to the Configuration utility to trusted management networks and enforce multi‑factor authentication for all users who can log in.
  • Implement network segmentation and strict firewall rules so that only authorized management hosts can reach the BIG‑IP or BIG‑IQ devices, and regularly monitor logs for unusual configuration changes.
