2019-01 Security Bulletin: Junos OS: SRX Series: Deleted dynamic VPN users are allowed to establish VPN connections until reboot (CVE-2019-0015)

  [JSA10915] Show Article Properties

Product Affected:
This issue affects Junos OS 12.3X48, 15.1X49, 17.3, 17.4, 18.1, 18.2. Affected platforms: SRX Series.

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.

Sample configuration:

user@host# show security dynamic-vpn
access-profile dyn-vpn-access-profile;
clients {
  grp {
      user {
