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-2023-3326 in the wild and no public exploit code.\n\nAffected product: Freebsd Freebsd. 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-2023-3326/ (Markdown: https://insights.sbomify.com/CVE-2023-3326/index.md)","id":"CVE-2023-3326","markdown":"https://insights.sbomify.com/CVE-2023-3326/index.md","name":"CVE-2023-3326","record":{"aliases":["DEBIAN-CVE-2023-3326","GHSA-vjhp-527w-c5vj","UBUNTU-CVE-2023-3326"],"analysis":{"component_type":"operating_system","fix_type":"configuration_change","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"FreeBSD Kerberos PAM","requires_auth":"none","summary":"Attackers can bypass authentication in FreeBSD using pam_krb5 without a keytab by controlling KDC responses, allowing unauthorized access to any user account.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"freebsd","cpe":[{"product":"freebsd","vendor":"freebsd"}],"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"},{"id":"CWE-303","name":"Incorrect Implementation of Authentication Algorithm"}],"description":"pam_krb5 authenticates a user by essentially running kinit with the password, getting a ticket-granting ticket (tgt) from the Kerberos KDC (Key Distribution Center) over the network, as a way to verify the password.
