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-2016-0756 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-2016-0756/ (Markdown: https://insights.sbomify.com/CVE-2016-0756/index.md)","id":"CVE-2016-0756","markdown":"https://insights.sbomify.com/CVE-2016-0756/index.md","name":"CVE-2016-0756","record":{"aliases":["DEBIAN-CVE-2016-0756","DLA-407-1","DSA-3463-1","GHSA-xf9v-h9f2-2phh","UBUNTU-CVE-2016-0756"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"XMPP server","requires_auth":"none","summary":"Remote attackers can spoof XMPP network domains by exploiting improper field separation in dialback key generation, bypassing domain verification.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"prosody","vendor":"prosody"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The generate_dialback function in the mod_dialback module in Prosody before 0.9.10 does not properly separate fields when generating dialback keys, which allows remote attackers to spoof XMPP network domains via a crafted stream id and domain name that is included in the target domain as a suffix.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Other in n/a","id":"CVE-2016-0756","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2016"},"n_packages":0,"n_references":8,"next":{"headline":"OpenStack Image Service (Glance) vulnerable to Improper Access Control","id":"CVE-2016-0757"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2016-0755"},"products":["n/a"],"published":"2016-01-29","related":[{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2014-2745","kev_date_added":null,"published":"2014-04-11"},{"cvss_score":7.5,"headline":"XML external entity in prosody","id":"CVE-2022-0217","kev_date_added":null,"published":"2022-08-26"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2021-37601","kev_date_added":null,"published":"2021-07-28"},{"cvss_score":6.5,"headline":"Missing authorization in Prosody","id":"CVE-2026-43504","kev_date_added":null,"published":"2026-05-01"},{"cvss_score":6.5,"headline":"Missing authorization in Prosody","id":"CVE-2026-43505","kev_date_added":null,"published":"2026-05-01"},{"cvss_score":5.3,"headline":"Denial of service in Prosody","id":"CVE-2026-43506","kev_date_added":null,"published":"2026-05-01"},{"cvss_score":5.3,"headline":"Denial of service in Prosody","id":"CVE-2026-43507","kev_date_added":null,"published":"2026-05-01"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can spoof XMPP network domains by exploiting improper field separation in dialback key generation, bypassing domain verification.","url":"https://insights.sbomify.com/CVE-2016-0756/"}
