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-2023-47102 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2023-47102/ (Markdown: https://insights.sbomify.com/CVE-2023-47102/index.md)","id":"CVE-2023-47102","markdown":"https://insights.sbomify.com/CVE-2023-47102/index.md","name":"CVE-2023-47102","record":{"aliases":["GHSA-q8x9-r7fc-qfjv"],"analysis":{"component_type":"server_software","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"UrBackup Server","requires_auth":"none","summary":"UrBackup Server allows attackers to enumerate valid user accounts by distinguishing between invalid and valid usernames via error messages.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"urbackup_server","vendor":"urbackup"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-203","name":"Observable Discrepancy"}],"description":"UrBackup Server 2.5.31 allows brute-force enumeration of user accounts because a failure message confirms that a username is not valid.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-10-31","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-10-31T04:03:02Z","kind":"github_poc","ref":"https://github.com/quantiano/cve-2023-47102","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":null,"headline":"Information disclosure in n/a","id":"CVE-2023-47102","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Command injection in n/a","id":"CVE-2023-47104"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2023-47101"},"products":["n/a"],"published":"2023-11-07","related":[{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2017-16950","kev_date_added":null,"published":"2017-12-17"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-09-29","vendors":["n/a"]},"summary":"UrBackup Server allows attackers to enumerate valid user accounts by distinguishing between invalid and valid usernames via error messages.","url":"https://insights.sbomify.com/CVE-2023-47102/"}
