Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2019-12991 in the wild since at least 25 Mar 2022.\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-2019-12991/ (Markdown: https://insights.sbomify.com/CVE-2019-12991/index.md)","id":"CVE-2019-12991","markdown":"https://insights.sbomify.com/CVE-2019-12991/index.md","name":"CVE-2019-12991","record":{"aliases":["GHSA-462p-6gjx-6wj6"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Citrix SD-WAN","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary commands on Citrix SD-WAN devices due to improper input validation, requiring an upgrade to secure versions.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"netscaler_sd-wan","vendor":"citrix"},{"product":"sd-wan","vendor":"citrix"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Citrix SD-WAN 10.2.x before 10.2.3 and NetScaler SD-WAN 10.0.x before 10.0.8 have Improper Input Validation (issue 5 of 6).","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2019-07-12","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2019-07-12","kind":"exploitdb","ref":"47112","stars":null,"title":"Citrix SD-WAN Appliance 10.2.2 - Authentication Bypass / Remote Command Execution"}],"tier":"exploited"},"has_fix":null,"headline":"Citrix SD-WAN and NetScaler Command Injection","id":"CVE-2019-12991","indexable":true,"kev":{"dateAdded":"2022-03-25","dueDate":"2022-04-15","knownRansomwareCampaignUse":"Unknown","product":"SD-WAN and NetScaler","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Citrix","vulnerabilityName":"Citrix SD-WAN and NetScaler Command Injection Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2019"},"n_packages":0,"n_references":4,"next":{"headline":"Command injection in n/a","id":"CVE-2019-12992"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2019-12990"},"products":["n/a"],"published":"2019-07-16","related":[{"cvss_score":9.8,"headline":"Citrix SD-WAN and NetScaler SQL Injection","id":"CVE-2019-12989","kev_date_added":"2022-03-25","published":"2019-07-16"},{"cvss_score":9.8,"headline":"Citrix Multiple Products Remote Code Execution","id":"CVE-2017-6316","kev_date_added":"2022-03-25","published":"2017-07-20"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2019-12985","kev_date_added":null,"published":"2019-07-16"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2019-12986","kev_date_added":null,"published":"2019-07-16"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2019-12987","kev_date_added":null,"published":"2019-07-16"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2019-12988","kev_date_added":null,"published":"2019-07-16"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["n/a"]},"summary":"Attackers can execute arbitrary commands on Citrix SD-WAN devices due to improper input validation, requiring an upgrade to secure versions.","url":"https://insights.sbomify.com/CVE-2019-12991/"}
