CVE-2026-28758
Full vulnerability record from the local CVENow database.
Description
When BIG-IP DNS is provisioned, a vulnerability exists in the gtm_add and bigip_add iControl REST commands that return the ssh-password parameter in cleartext in the iControl REST response and is also logged in the audit log. This may allow a highly privileged, authenticated attacker with access to the audit log to view sensitive information. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated
