On F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.2, or 11.2.1-11.6.3.1, Enterprise Manager 3.1.1, BIG-IQ Centralized Management 5.0.0-5.4.0 or 4.6.0, BIG-IQ Cloud and Orchestration 1.0.0, or F5 iWorkflow 2.0.2-2.3.0, authenticated users granted TMOS Shell (tmsh) access can access objects on the file system which would normally be disallowed by tmsh restrictions. This allows for authenticated, low privileged attackers to exfiltrate objects on the file system which should not be allowed.

Security readout for executives and security teams

CVE-2018-5516 lets authenticated, low-privileged F5 users with TMOS Shell access read filesystem objects that tmsh restrictions should block. The main business risk is disclosure of sensitive appliance files or configuration data. The source bundle does not provide CVSS scoring or confirm public exploitation. Exposure is most likely where affected F5 versions remain deployed and non-administrator users have tmsh access. Internet exposure is not required by the description, but compromise or misuse of valid appliance credentials raises risk. Prioritize remediation on F5 systems with multiple operators, shared administration, or sensitive configuration data. This is not sourced as actively exploited, but it weakens privilege boundaries on critical network infrastructure. Mitigation focus: Check F5 advisory K37442533 for supported fixed versions and official remediation guidance.; Inventory affected F5 products and retire or upgrade versions in the listed ranges.; Restrict tmsh access to users with a clear operational need..
