A vulnerability was found in Juniper Junos on SRX (Router Operating System) (the affected version is unknown). It has been rated as critical. Affected by this issue is an unknown code of the component VPN Handler. The manipulation with an unknown input leads to a improper authentication vulnerability. Using CWE to declare the problem leads to CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. Impacted is confidentiality, integrity, and availability. CVE summarizes:

A vulnerability in the SRX Series Service Gateway allows deleted dynamic VPN users to establish dynamic VPN connections until the device is rebooted. A deleted dynamic VPN connection should be immediately disallowed from establishing new VPN connections. Due to an error in token caching, deleted users are allowed to connect once a previously successful dynamic VPN connection has been established. A reboot is required to clear the cached authentication token. Affected releases are Junos OS on SRX Series: 12.3X48 versions prior to 12.3X48-D75; 15.1X49 versions prior to 15.1X49-D150; 17.3 versions prior to 17.3R3; 17.4 versions prior to 17.4R2; 18.1 versions prior to 18.1R3; 18.2 versions prior to 18.2R2.
