CVE-2026-20916
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk28th percentile - higher than 28% of all known CVEs
Summary
An authenticated iControl REST user with low privileges can create or modify arbitrary files through an undisclosed iControl REST endpoint on the BIG-IQ system. The vulnerability affects software versions that have not reached End of Technical Support.
Risk Assessment
The risk includes unauthorized modification of configuration or system files, potentially leading to privilege escalation, system integrity compromise, or full control over the BIG-IQ device.
Recommendation
It is recommended to immediately apply vendor-provided patches and restrict access to the iControl REST interface to trusted users and networks only.
