When the F5 BIG-IP 12.1.0-12.1.1, 11.6.0-11.6.1, 11.5.1-11.5.5, or 11.2.1 system is configured with a wildcard IPSec tunnel endpoint, it may allow a remote attacker to disrupt or impersonate the tunnels that have completed phase 1 IPSec negotiations. The attacker must possess the necessary credentials to negotiate the phase 1 of the IPSec exchange to exploit this vulnerability; in many environment this limits the attack surface to other endpoints under the same administration.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.4, indicating it can be exploited remotely over the network but requires specific conditions to be met without requiring user interaction requiring only low-level privileges . The vulnerability impacts limited data confidentiality, limited integrity, and availability (service disruption) for affected systems. Impacting 13 products from f5, from f5, from f5 and 10 others, organizations running these solutions should prioritize assessment and patching.
First disclosed in 2018, 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.
