      "summary": "A Use of Incorrectly-Resolved Name or Reference vulnerability in the URL filtering plugin of Juniper Networks Junos OS on MX Series allows an unauthenticated, network-based attacker to bypass web filtering and access downstream resources that should be unreachable.\n\n\n\nIf an MX Series device is configured with web filtering, and an attacker sends a request with a specifically formatted URL, this request will get forwarded despite the system being configured to block it. In turn, an attacker can access downstream resources that are expected to be unreachable.\n\nThis issue affects Junos OS on MX Series:\n\n\n  *  all versions before 23.2R2-S7,\n  *  23.4 versions before 23.4R2-S8,\n  *  24.2 versions before 24.2R2-S5,\n  *  24.4 versions before 24.4R2-S4,\n  *  25.2 versions before 25.2R2-S1,\n  *  25.4 versions before 25.4R1-S2, 25.4R2.",
