Descriptions

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.
