In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, GTM, Link Controller, PEM, WebAccelerator software version 12.0.0 - 12.1.2, 11.6.0 - 11.6.1, 11.4.0 - 11.5.4, 11.2.1, when ConfigSync is configured, attackers on adjacent networks may be able to bypass the TLS protections usually used to encrypted and authenticate connections to mcpd. This vulnerability may allow remote attackers to cause a denial-of-service (DoS) attack via resource exhaustion.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 5.3, indicating it requires adjacent network access but requires specific conditions to be met without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts and availability (service disruption) for affected systems. Impacting 11 products from f5, from f5, from f5 and 8 others, organizations running these solutions should prioritize assessment and patching.
First disclosed in 2017, this vulnerability was reported during a period defined by widespread IoT adoption challenges, mobile security concerns, and the emergence of advanced persistent threat (APT) techniques. Contemporary mitigation strategies focused on secure development practices and third-party component vetting.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For f5's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
