BIG-IP scripted monitor vulnerability

Published May 13, 2026 CVSS 4.0 · 8.5 High EPSS < 1% KEV · Not listed
Description
A vulnerability exists in BIG-IP scripted monitors that may allow an authenticated attacker with the Resource Administrator or Administrator role to execute arbitrary system commands with higher privileges. In appliance mode deployments, a successful exploit can allow the attacker to cross a security boundary.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Analysis

AI-generated

Technical impact

A vulnerability in BIG‑IP scripted monitors allows an authenticated attacker who holds the Resource Administrator or Administrator role to execute arbitrary system commands with higher privileges. When deployed in appliance mode, a successful exploitation can cross a security boundary, allowing the attacker to affect parts of the system that would normally be protected.

Affected Systems

The affected product is F5 BIG‑IP. No specific version information is provided in the advisory. Software that has reached End of Technical Support is not evaluated.

Risk and Exploitability

The CVSS score of 8.5 indicates a high severity risk. EPSS data is unavailable and the vulnerability is not listed in the CISA KEV catalog. Exploitation requires valid authentication with one of the privileged roles and is therefore limited to users who have been granted access to the BIG‑IP management interface. Once authenticated, the attacker can execute commands that may compromise the host operating system and potentially breach internal security controls.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the latest F5 BIG‑IP patch or firmware release that addresses the scripted monitor flaw.
  • Restrict the Resource Administrator and Administrator roles so that only trusted users can edit or deploy scripted monitors, or remove those roles entirely if possible.
  • Disable scripted monitors in appliance mode or replace them with standard, non‑scripted monitoring mechanisms.
