An Incorrect Authorization vulnerability in the web server of Juniper Networks Junos OS on SRX Series allows an unauthen

An Incorrect Authorization vulnerability in the web server of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to reach the Juniper Web Device Manager (J-Web). When Juniper Secure connect (JSC) is enabled on specific interfaces, or multiple interfaces are configured for J-Web, the J-Web UI is reachable over more than the intended interfaces. This issue affects Junos OS: all versions before 21.4R3-S9, 22.2 versions before 22.2R3-S5, 22.4 versions before 22.4R3-S5, 23.2 versions before 23.2R2-S3, 23.4 versions before 23.4R2-S5, 24.2 versions before 24.2R2.
