An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-52981 in the wild and no public exploit code.\n\nAffected product: Juniper Junos. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-52981/ (Markdown: https://insights.sbomify.com/CVE-2025-52981/index.md)","id":"CVE-2025-52981","markdown":"https://insights.sbomify.com/CVE-2025-52981/index.md","name":"CVE-2025-52981","record":{"aliases":["GHSA-j2f6-v4vj-2456"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Juniper SRX firewall","requires_auth":"none","summary":"An unauthenticated attacker can cause a denial of service on Juniper SRX firewalls by sending specific PIM packets that crash the flow processing daemon.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[{"product":"junos","vendor":"juniper"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L/AU:Y/R:A/RE:M","version":"4.0"},"cwes":[{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"}],"description":"An Improper Check for Unusual or Exceptional Conditions vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on \n\nSRX1600, SRX2300, SRX 4000 Series, and SRX5000 Series with SPC3\n\nallows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).\n\nIf a sequence of specific PIM packets is received, this will cause a flowd crash and restart.\n\nThis issue affects Junos OS:\n\n  *  all versions before 21.2R3-S9,\n  *  21.4 versions before 21.4R3-S11,\n  *  22.2 versions before 22.2R3-S7,\n  *  22.4 versions before 22.4R3-S6,\n  *  23.2 versions before 23.2R2-S4,\n  *  23.4 versions before 23.4R2-S4,\n  *  24.2 versions before 24.2R2.\n\nThis is a similar, but different vulnerability than the issue reported as\n\nCVE-2024-47503, published in JSA88133.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Junos OS: SRX Series: Sequence of specific PIM packets causes a flowd crash","id":"CVE-2025-52981","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"juniper:junos","products":["juniper:junos"],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Junos OS: MX Series: When specific SIP packets are processed the MS-MPC will crash","id":"CVE-2025-52982"},"packages":[],"prev":{"headline":"Junos OS: SRX300 Series: rpd will crash upon receiving a specific, valid BGP UPDATE message","id":"CVE-2025-52980"},"products":["Junos OS"],"published":"2025-07-11","related":[{"cvss_score":9.8,"headline":"Juniper Junos OS EX Series and SRX Series PHP External Variable Modification","id":"CVE-2023-36845","kev_date_added":"2023-11-13","published":"2023-08-17"},{"cvss_score":8.8,"headline":"Juniper Junos OS Path Traversal","id":"CVE-2020-1631","kev_date_added":"2022-03-25","published":"2020-05-04"},{"cvss_score":6.7,"headline":"Juniper Junos OS Improper Isolation or Compartmentalization","id":"CVE-2025-21590","kev_date_added":"2025-03-13","published":"2025-03-12"},{"cvss_score":5.3,"headline":"Juniper Junos OS SRX Series Missing Authentication for Critical Function","id":"CVE-2023-36851","kev_date_added":"2023-11-13","published":"2023-09-26"},{"cvss_score":5.3,"headline":"Juniper Junos OS EX Series PHP External Variable Modification","id":"CVE-2023-36844","kev_date_added":"2023-11-13","published":"2023-08-17"},{"cvss_score":5.3,"headline":"Juniper Junos OS SRX Series Missing Authentication for Critical Function","id":"CVE-2023-36846","kev_date_added":"2023-11-13","published":"2023-08-17"},{"cvss_score":5.3,"headline":"Juniper Junos OS EX Series Missing Authentication for Critical Function","id":"CVE-2023-36847","kev_date_added":"2023-11-13","published":"2023-08-17"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-07-15","vendors":["Juniper Networks"]},"summary":"An unauthenticated attacker can cause a denial of service on Juniper SRX firewalls by sending specific PIM packets that crash the flow processing daemon.","url":"https://insights.sbomify.com/CVE-2025-52981/"}
