{"id":"CVE-2025-52982","state":"PUBLISHED","title":"Junos OS: MX Series: When specific SIP packets are processed the MS-MPC will crash","description":"An Improper Resource Shutdown or Release vulnerability in the SIP ALG of Juniper Networks Junos OS on MX Series with MS-MPC allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).\n\nWhen an MX Series device with an MS-MPC is configured with two or more service sets which are both processing SIP calls, a specific sequence of call events will lead to a crash and restart of the MS-MPC.\nThis issue affects Junos OS:\n\n\n\n  *  all versions before 21.2R3-S9,\n  *  21.4 versions from 21.4R1,\n  *  22.2 versions before 22.2R3-S6,\n  *  22.4 versions before 22.4R3-S6.\n\n\n\n\nAs the MS-MPC is EoL after Junos OS 22.4, later versions are not affected.\n\nThis issue does not affect MX-SPC3 or SRX Series devices.","publishedAt":"2025-07-11T15:08:53.931Z","updatedAt":"2025-07-15T19:55:34.678Z","severity":{"score":8.2,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L/AU:Y/R:A/RE:M","source":"juniper"},"assigner":"juniper","products":["Juniper
