An issue was discovered in VxWorks 6.9 through 7. In the IKE component, a specifically crafted packet may lead to reading beyond the end of a buffer, or a double free. CVSS score: https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator?vector=AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L&version=3.1 Metric Value Comments Attack Vector Network The vulnerable component is IKE which bound to the network stack, The attacker can exploit crafted IKE packet to trigger the vulnerability across a wide area network Attack Complexity Low The attacker just needs construct specialized IKE packet Privileges Required None The attacker can exploit the vulnerability as long as he is able to send packet to the IKE service. User Interaction None No user interaction needed from any user Scope Unchanged Only IKE itself would be affected. Confidentiality None No information would be returned to attached after a successful exploited vulnerability Integrity Low In most of scenario, the specifically crafted packet lead to reading beyond the end of a buffer, there is no change of anything. while in a specific scenario, it may lead double-free which will modify data in theory. this is limited in IKE component, no impact to whole system Availability Low The impact is only limited to IKE component while VxWorks is still in service when attack happened
