An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2019-19781 in the wild since at least 3 Nov 2021, including in ransomware campaigns.\n\nAffected product: n/a. 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-2019-19781/ (Markdown: https://insights.sbomify.com/CVE-2019-19781/index.md)","id":"CVE-2019-19781","markdown":"https://insights.sbomify.com/CVE-2019-19781/index.md","name":"CVE-2019-19781","record":{"aliases":["GHSA-jjcm-f6q3-w5xj"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Citrix ADC Gateway","requires_auth":"none","summary":"Attackers can exploit directory traversal in Citrix ADC and Gateway to execute arbitrary code or read sensitive data.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"application_delivery_controller_firmware","vendor":"citrix"},{"product":"gateway_firmware","vendor":"citrix"},{"product":"netscaler_gateway_firmware","vendor":"citrix"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"An issue was discovered in Citrix Application Delivery Controller (ADC) and Gateway 10.5, 11.1, 12.0, 12.1, and 13.0.
