Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-39528 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-2024-39528/ (Markdown: https://insights.sbomify.com/CVE-2024-39528/index.md)","id":"CVE-2024-39528","markdown":"https://insights.sbomify.com/CVE-2024-39528/index.md","name":"CVE-2024-39528","record":{"aliases":["GHSA-2pf5-j72f-jhxp"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Juniper Junos OS","requires_auth":"low_privilege","summary":"An authenticated attacker can crash the routing daemon by triggering a race condition between instance deletion and SNMP requests, causing denial of service.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[{"product":"junos","vendor":"juniper"},{"product":"junos_os_evolved","vendor":"juniper"}],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L","version":"4.0"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"A Use After Free vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an authenticated, network-based attacker to cause a Denial of Service (DoS).On all Junos OS and Junos Evolved platforms, if a routing-instance deactivation is triggered, and at the same time a specific SNMP request is received, a segmentation fault occurs which causes rpd to crash and restart.\n\nThis issue affects:\n\n   Junos OS:\n\n  *  All versions before 21.2R3-S8, \n  *  21.4 versions before 21.4R3-S5,\n  *  22.2 versions before 22.2R3-S3,\n  *  22.3 versions before 22.3R3-S2,\n  *  22.4 versions before 22.4R3,\n  *  23.2 versions before 23.2R2.\n\n   Junos OS Evolved:\n\n  *  All versions before 21.2R3-S8-EVO,\n  *  21.4-EVO versions before 21.4R3-S5-EVO,\n  *  22.2-EVO versions before 22.2R3-S3-EVO, \n  *  22.3-EVO versions before 22.3R3-S2-EVO,\n  *  22.4-EVO versions before 22.4R3-EVO,\n  *  23.2-EVO versions before 23.2R2-EVO.","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":"Use after free in Junos OS","id":"CVE-2024-39528","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"juniper:junos","products":["juniper:junos","juniper:junos_os_evolved"],"type":"use_after_free","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in Junos OS","id":"CVE-2024-39529"},"packages":[],"prev":{"headline":"Junos OS: SRX Series: Low privileged user able to access sensitive information on file system","id":"CVE-2024-39527"},"products":["Junos OS","Junos OS Evolved"],"published":"2024-07-11","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-02","vendors":["Juniper Networks"]},"summary":"An authenticated attacker can crash the routing daemon by triggering a race condition between instance deletion and SNMP requests, causing denial of service.","url":"https://insights.sbomify.com/CVE-2024-39528/"}
