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-2020-8086 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2020-8086/ (Markdown: https://insights.sbomify.com/CVE-2020-8086/index.md)","id":"CVE-2020-8086","markdown":"https://insights.sbomify.com/CVE-2020-8086/index.md","name":"CVE-2020-8086","record":{"aliases":["DEBIAN-CVE-2020-8086","DSA-4612-1","GHSA-hq2x-6q7v-jx98","UBUNTU-CVE-2020-8086"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Prosody XMPP server","requires_auth":"none","summary":"Remote attackers can gain admin privileges by matching a local admin username due to incomplete verification in Prosody's LDAP authentication modules.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"mod_auth_ldap","vendor":"prosody"},{"product":"mod_auth_ldap2","vendor":"prosody"}],"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-863","name":"Incorrect Authorization"}],"description":"The mod_auth_ldap and mod_auth_ldap2 Community Modules through 2020-01-27 for Prosody incompletely verify the XMPP address passed to the is_admin() function.
