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-2023-28507 in the wild and no public exploit code.\n\nAffected product: Rocket Software UniData. 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-2023-28507/ (Markdown: https://insights.sbomify.com/CVE-2023-28507/index.md)","id":"CVE-2023-28507","markdown":"https://insights.sbomify.com/CVE-2023-28507/index.md","name":"CVE-2023-28507","record":{"aliases":["GHSA-pvmm-fgf7-r833"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Rocket UniData/UniVerse","requires_auth":"none","summary":"Attackers can cause denial of service in Rocket UniData and UniVerse by triggering memory exhaustion during LZ4 decompression.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"rapid7","cpe":[{"product":"unidata","vendor":"rocketsoftware"},{"product":"universe","vendor":"rocketsoftware"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Rocket Software UniData versions prior to 8.2.4 build 3003 and UniVerse versions prior to 11.3.5 build 1001 or 12.2.1 build 2002 suffer from a memory-exhaustion issue, where a decompression routine will allocate increasing amounts of memory until all system memory is exhausted and the forked process crashes.","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":"Memory exhaustion in LZ4 decompression in UniRPC daemon","id":"CVE-2023-28507","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Heap corruption in UniRPC service","id":"CVE-2023-28508"},"packages":[],"prev":{"headline":"Stack buffer overflow in UniRPC service","id":"CVE-2023-28506"},"products":["UniData","UniVerse"],"published":"2023-03-29","related":[{"cvss_score":9.8,"headline":"Heap buffer overflow in unirpcd","id":"CVE-2023-28501","kev_date_added":null,"published":"2023-03-29"},{"cvss_score":9.8,"headline":"Stack buffer overflow in UniRPC's udadmin_server service","id":"CVE-2023-28502","kev_date_added":null,"published":"2023-03-29"},{"cvss_score":9.8,"headline":"Authentication bypass in UniRPC's udadmin service","id":"CVE-2023-28503","kev_date_added":null,"published":"2023-03-29"},{"cvss_score":9.8,"headline":"Stack buffer overflow in UniRPC library function","id":"CVE-2023-28504","kev_date_added":null,"published":"2023-03-29"},{"cvss_score":8.8,"headline":"Stack buffer overflow in UniRPC service","id":"CVE-2023-28506","kev_date_added":null,"published":"2023-03-29"},{"cvss_score":8.8,"headline":"Heap corruption in UniRPC service","id":"CVE-2023-28508","kev_date_added":null,"published":"2023-03-29"}],"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":"total"},"state":"PUBLISHED","updated":"2025-02-18","vendors":["Rocket Software"]},"summary":"Attackers can cause denial of service in Rocket UniData and UniVerse by triggering memory exhaustion during LZ4 decompression.","url":"https://insights.sbomify.com/CVE-2023-28507/"}
