Description
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.
