An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-28503 exists.\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-2023-28503/ (Markdown: https://insights.sbomify.com/CVE-2023-28503/index.md)","id":"CVE-2023-28503","markdown":"https://insights.sbomify.com/CVE-2023-28503/index.md","name":"CVE-2023-28503","record":{"aliases":["GHSA-g594-6376-7c5r"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Rocket Software UniData","requires_auth":"none","summary":"Attackers can bypass authentication using a hardcoded credential to execute OS commands as root on Rocket Software UniData and UniVerse servers.","user_interaction":"not_required","vuln_class":"auth_bypass"},"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-287","name":"Improper Authentication"},{"id":"CWE-798","name":"Use of Hard-coded Credentials"}],"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 an authentication bypass vulnerability, where a special username with a deterministic password can be leveraged to bypass authentication checks and execute OS commands as the root user.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-03-30","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2023-03-30","kind":"metasploit","ref":"exploit/linux/misc/unidata_udadmin_auth_bypass","stars":null,"title":"Rocket Software Unidata udadmin_server Authentication Bypass"}],"tier":"weaponised"},"has_fix":null,"headline":"Authentication bypass in UniRPC's udadmin service","id":"CVE-2023-28503","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Stack buffer overflow in UniRPC library function","id":"CVE-2023-28504"},"packages":[],"prev":{"headline":"Stack buffer overflow in UniRPC's udadmin_server service","id":"CVE-2023-28502"},"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":"Stack buffer overflow in UniRPC library function","id":"CVE-2023-28504","kev_date_added":null,"published":"2023-03-29"},{"cvss_score":9.8,"headline":"Memory exhaustion in LZ4 decompression in UniRPC daemon","id":"CVE-2023-28507","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)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-18","vendors":["Rocket Software"]},"summary":"Attackers can bypass authentication using a hardcoded credential to execute OS commands as root on Rocket Software UniData and UniVerse servers.","url":"https://insights.sbomify.com/CVE-2023-28503/"}
