An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-23903 in the wild and no public exploit code.\n\nAffected product: Nozomi Networks CMC. 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-2023-23903/ (Markdown: https://insights.sbomify.com/CVE-2023-23903/index.md)","id":"CVE-2023-23903","markdown":"https://insights.sbomify.com/CVE-2023-23903/index.md","name":"CVE-2023-23903","record":{"aliases":["GHSA-fp89-4294-45q3"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Nozomi Networks CMC","requires_auth":"high_privilege","summary":"An authenticated administrator can cause a denial of service by uploading a malformed SAML configuration file, rendering the application unusable.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Nozomi","cpe":[{"product":"cmc","vendor":"nozominetworks"},{"product":"guardian","vendor":"nozominetworks"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1286","name":"Improper Validation of Syntactic Correctness of Input"}],"description":"An authenticated administrator can upload a SAML configuration file with the wrong format, with the application not checking the correct file format.
