MZK-DP300N, published on 8 Jan 2025. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-21603 in the wild and no public exploit code.\n\nAffected product: PLANEX COMMUNICATIONS INC. MZK-DP300N. 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-2025-21603/ (Markdown: https://insights.sbomify.com/CVE-2025-21603/index.md)","id":"CVE-2025-21603","markdown":"https://insights.sbomify.com/CVE-2025-21603/index.md","name":"CVE-2025-21603","record":{"aliases":["GHSA-34w5-cvqh-fxgw"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"MZK-DP300N firmware","requires_auth":"high_privilege","summary":"An authenticated attacker can execute arbitrary scripts in a victim's browser via crafted URLs in the MZK-DP300N firmware.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross-site scripting vulnerability exists in MZK-DP300N firmware versions 1.05 and earlier.
