An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-1756 in the wild and no public exploit code.\n\nAffected product: Cisco Ios. 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-2019-1756/ (Markdown: https://insights.sbomify.com/CVE-2019-1756/index.md)","id":"CVE-2019-1756","markdown":"https://insights.sbomify.com/CVE-2019-1756/index.md","name":"CVE-2019-1756","record":{"aliases":["GHSA-c5vj-536j-jp5v"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco IOS XE","requires_auth":"high_privilege","summary":"Authenticated attackers can execute arbitrary root commands on Cisco IOS XE devices via malicious input in the web UI, leading to full system compromise.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios","vendor":"cisco"},{"product":"ios_xe","vendor":"cisco"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability in Cisco IOS XE Software could allow an authenticated, remote attacker to execute commands on the underlying Linux shell of an affected device with root privileges. The vulnerability occurs because the affected software improperly sanitizes user-supplied input. An attacker who has valid administrator access to an affected device could exploit this vulnerability by supplying a username with a malicious payload in the web UI and subsequently making a request to a specific endpoint in the web UI.
