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-2023-43742 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-2023-43742/ (Markdown: https://insights.sbomify.com/CVE-2023-43742/index.md)","id":"CVE-2023-43742","markdown":"https://insights.sbomify.com/CVE-2023-43742/index.md","name":"CVE-2023-43742","record":{"aliases":["GHSA-fvq3-8fqq-2cvh"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Zultys MX PBX","requires_auth":"none","summary":"Unauthenticated attackers can gain administrative access by ignoring login failure messages, allowing full control of the Zultys MX PBX system.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mx-e_firmware","vendor":"zultys"},{"product":"mx-se_firmware","vendor":"zultys"},{"product":"mx-se_ii_firmware","vendor":"zultys"},{"product":"mx-virtual_firmware","vendor":"zultys"},{"product":"mx250_firmware","vendor":"zultys"},{"product":"mx30_firmware","vendor":"zultys"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","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"}],"description":"An authentication bypass in Zultys MX-SE, MX-SE II, MX-E, MX-Virtual, MX250, and MX30 with firmware versions prior to 17.0.10 patch 17161 and 16.04 patch 16109 allows an unauthenticated attacker to obtain an administrative session via a protection mechanism failure in the authentication function. In normal operation, the Zultys MX Administrator Windows client connects to port 7505 and attempts authentication, submitting the administrator username and password to the server. Upon authentication failure, the server sends a login failure message prompting the client to disconnect. However, if the client ignores the failure message instead and attempts to continue, the server does not forcibly close the connection and processes all subsequent requests from the client as if authentication had been successful.","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":"Auth bypass in n/a","id":"CVE-2023-43742","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"SQL injection in n/a","id":"CVE-2023-43743"},"packages":[],"prev":{"headline":"Buildkite Elastic CI for AWS time-of-check-time-of-use race condition vulnerability","id":"CVE-2023-43741"},"products":["n/a"],"published":"2023-12-08","related":[{"cvss_score":8.8,"headline":"SQL injection in n/a","id":"CVE-2023-43743","kev_date_added":null,"published":"2023-12-08"},{"cvss_score":7.2,"headline":"Command injection in n/a","id":"CVE-2023-43744","kev_date_added":null,"published":"2023-12-08"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-02","vendors":["n/a"]},"summary":"Unauthenticated attackers can gain administrative access by ignoring login failure messages, allowing full control of the Zultys MX PBX system.","url":"https://insights.sbomify.com/CVE-2023-43742/"}
