Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-30550 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-2022-30550/ (Markdown: https://insights.sbomify.com/CVE-2022-30550/index.md)","id":"CVE-2022-30550","markdown":"https://insights.sbomify.com/CVE-2022-30550/index.md","name":"CVE-2022-30550","record":{"aliases":["ALPINE-CVE-2022-30550","ALSA-2022:7623","ALSA-2022:8208","AZL-10311","AZL-44649","CLSA-2022-1659635856","CLSA-2022-1659635964","DEBIAN-CVE-2022-30550","GHSA-cch8-vp96-g53m","MGASA-2022-0296","OESA-2022-1994","RHSA-2022:7623","RHSA-2022:8208","RLSA-2022:7623","RLSA-2022:8208","SUSE-SU-2022:2431-1","SUSE-SU-2022:2432-1","SUSE-SU-2022:2448-1","SUSE-SU-2022:2618-1","UBUNTU-CVE-2022-30550","USN-5509-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"Dovecot mail server","requires_auth":"low_privilege","summary":"Incorrect application of username_filter settings in Dovecot passdb configurations can allow privilege escalation when duplicate driver entries exist.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"dovecot","vendor":"dovecot"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"An issue was discovered in the auth component in Dovecot 2.2 and 2.3 before 2.3.20. When two passdb configuration entries exist with the same driver and args settings, incorrect username_filter and mechanism settings can be applied to passdb definitions. These incorrectly applied settings can lead to an unintended security configuration and can permit privilege escalation in certain configurations. The documentation does not advise against the use of passdb definitions that have the same driver and args settings. One such configuration would be where an administrator wishes to use the same PAM configuration or passwd file for both normal and master users but use the username_filter setting to restrict which of the users is able to be a master user.","ecosystems":["AlmaLinux:8","AlmaLinux:9","Red Hat:enterprise_linux:8::appstream","Red Hat:enterprise_linux:8::crb","Red Hat:enterprise_linux:9::appstream","Red
