Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2016-4923 in the wild and no public exploit code.\n\nAffected product: Juniper Junos. 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-2016-4923/ (Markdown: https://insights.sbomify.com/CVE-2016-4923/index.md)","id":"CVE-2016-4923","markdown":"https://insights.sbomify.com/CVE-2016-4923/index.md","name":"CVE-2016-4923","record":{"aliases":["GHSA-8p6g-483j-rff7"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Junos OS J-Web","requires_auth":"low_privilege","summary":"Remote unauthenticated attackers can inject scripts into Junos J-Web to steal credentials and perform administrative actions on the device.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[{"product":"junos","vendor":"juniper"}],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Insufficient cross site scripting protection in J-Web component in Juniper Networks Junos OS may potentially allow a remote unauthenticated user to inject web script or HTML and steal sensitive data and credentials from a J-Web session and to perform administrative actions on the Junos device.
