Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-27978 in the wild and no public exploit code.\n\nAffected product: Ivanti Avalanche. 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-2024-27978/ (Markdown: https://insights.sbomify.com/CVE-2024-27978/index.md)","id":"CVE-2024-27978","markdown":"https://insights.sbomify.com/CVE-2024-27978/index.md","name":"CVE-2024-27978","record":{"aliases":["GHSA-g23v-56px-8cqm"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Ivanti Avalanche","requires_auth":"low_privilege","summary":"An authenticated remote attacker can cause a denial of service in Ivanti Avalanche via a null pointer dereference in the WLAvalancheService component.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"avalanche","vendor":"ivanti"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"A Null Pointer Dereference vulnerability in WLAvalancheService component of Ivanti Avalanche before 6.4.3 allows an authenticated remote attacker to perform denial of service attacks.","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":"Null dereference in Avalanche","id":"CVE-2024-27978","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ivanti:avalanche","products":["ivanti:avalanche"],"type":"null_dereference","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in Node","id":"CVE-2024-27980"},"packages":[],"prev":{"headline":"Path traversal in Avalanche","id":"CVE-2024-27977"},"products":["Avalanche"],"published":"2024-04-19","related":[{"cvss_score":9.8,"headline":"Memory corruption in Avalanche","id":"CVE-2023-38036","kev_date_added":null,"published":"2025-07-12"},{"cvss_score":9.8,"headline":"Memory corruption in Avalanche","id":"CVE-2024-24996","kev_date_added":null,"published":"2024-04-19"},{"cvss_score":9.8,"headline":"Memory corruption in Avalanche","id":"CVE-2024-29204","kev_date_added":null,"published":"2024-04-19"},{"cvss_score":9.8,"headline":"Memory corruption in Wavelink","id":"CVE-2023-41727","kev_date_added":null,"published":"2023-12-19"},{"cvss_score":9.8,"headline":"Memory corruption in Wavelink","id":"CVE-2023-46216","kev_date_added":null,"published":"2023-12-19"},{"cvss_score":9.8,"headline":"Memory corruption in Wavelink","id":"CVE-2023-46217","kev_date_added":null,"published":"2023-12-19"},{"cvss_score":9.8,"headline":"Memory corruption in Avalanche","id":"CVE-2023-46220","kev_date_added":null,"published":"2023-12-19"}],"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":["Ivanti"]},"summary":"An authenticated remote attacker can cause a denial of service in Ivanti Avalanche via a null pointer dereference in the WLAvalancheService component.","url":"https://insights.sbomify.com/CVE-2024-27978/"}
