Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-17477 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-2020-17477/ (Markdown: https://insights.sbomify.com/CVE-2020-17477/index.md)","id":"CVE-2020-17477","markdown":"https://insights.sbomify.com/CVE-2020-17477/index.md","name":"CVE-2020-17477","record":{"aliases":["GHSA-39vr-m637-4v3h"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"UCS@school LDAP plugin","requires_auth":"low_privilege","summary":"Remote users can read LDAP password hashes due to incorrect ACLs, potentially leading to privilege escalation via NTLM hash reuse.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ucs\\@school","vendor":"univention"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-522","name":"Insufficiently Protected Credentials"}],"description":"Incorrect LDAP ACLs in ucs-school-ldap-acls-master in UCS@school before 4.4v5-errata allow remote teachers, staff, and school administrators to read LDAP password hashes (sambaNTPassword, krb5Key, sambaPasswordHistory, and pwhistory) via LDAP search requests.
