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-2017-11103 in the wild and no public exploit code.\n\nAffected product: Apple Iphone Os. 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-2017-11103/ (Markdown: https://insights.sbomify.com/CVE-2017-11103/index.md)","id":"CVE-2017-11103","markdown":"https://insights.sbomify.com/CVE-2017-11103/index.md","name":"CVE-2017-11103","record":{"aliases":["ALPINE-CVE-2017-11103","CLEANSTART-2024-WM93067","DEBIAN-CVE-2017-11103","DLA-1027-1","DSA-3909-1","DSA-3912-1","ECHO-5fb5-4f74-b231","GHSA-7cm4-q9wm-9w5g","MGASA-2017-0265","MGASA-2017-0326","SUSE-SU-2017:2237-1","UBUNTU-CVE-2017-11103","USN-3353-1","USN-3353-2"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Kerberos authentication library","requires_auth":"none","summary":"Remote attackers can impersonate services by exploiting a Kerberos protocol violation in Heimdal, allowing unauthorized access and potential account takeover.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"iphone_os","vendor":"apple"},{"product":"mac_os_x","vendor":"apple"},{"product":"debian_linux","vendor":"debian"},{"product":"freebsd","vendor":"freebsd"},{"product":"heimdal","vendor":"heimdal_project"},{"product":"samba","vendor":"samba"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"Heimdal before 7.4 allows remote attackers to impersonate services with Orpheus' Lyre attacks because it obtains service-principal names in a way that violates the Kerberos 5 protocol specification. In _krb5_extract_ticket() the KDC-REP service name must be obtained from the encrypted version stored in 'enc_part' instead of the unencrypted version stored in 'ticket'. Use of the unencrypted version provides an opportunity for successful server impersonation and other attacks.
