Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-22913 in the wild and no public exploit code.\n\nAffected product: Zyxel USG FLEX series firmware. 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-2023-22913/ (Markdown: https://insights.sbomify.com/CVE-2023-22913/index.md)","id":"CVE-2023-22913","markdown":"https://insights.sbomify.com/CVE-2023-22913/index.md","name":"CVE-2023-22913","record":{"aliases":["GHSA-g276-jg34-q58g"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Zyxel USG FLEX firmware","requires_auth":"low_privilege","summary":"Authenticated attackers can inject commands via a CGI script to modify configuration and cause denial of service on Zyxel USG FLEX and VPN devices.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"usg_flex_100_firmware","vendor":"zyxel"},{"product":"usg_flex_100w_firmware","vendor":"zyxel"},{"product":"usg_flex_200_firmware","vendor":"zyxel"},{"product":"usg_flex_500_firmware","vendor":"zyxel"},{"product":"usg_flex_50_firmware","vendor":"zyxel"},{"product":"usg_flex_50w_firmware","vendor":"zyxel"},{"product":"usg_flex_700_firmware","vendor":"zyxel"},{"product":"vpn1000_firmware","vendor":"zyxel"},{"product":"vpn100_firmware","vendor":"zyxel"},{"product":"vpn300_firmware","vendor":"zyxel"},{"product":"vpn50_firmware","vendor":"zyxel"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"A post-authentication command injection vulnerability in the “account_operator.cgi” CGI program of Zyxel USG FLEX series firmware versions 4.50 through 5.35, and VPN series firmware versions 4.30 through 5.35, which could allow a remote authenticated attacker to modify device configuration data, resulting in denial-of-service (DoS) conditions on an affected device.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Command injection in USG FLEX series firmware","id":"CVE-2023-22913","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in USG FLEX series firmware","id":"CVE-2023-22914"},"packages":[],"prev":{"headline":"Weak cryptography in n/a","id":"CVE-2023-22912"},"products":["USG FLEX series firmware","VPN series firmware"],"published":"2023-04-24","related":[{"cvss_score":7.2,"headline":"Path traversal in USG FLEX series firmware","id":"CVE-2023-22914","kev_date_added":null,"published":"2023-04-24"}],"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":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-12","vendors":["Zyxel"]},"summary":"Authenticated attackers can inject commands via a CGI script to modify configuration and cause denial of service on Zyxel USG FLEX and VPN devices.","url":"https://insights.sbomify.com/CVE-2023-22913/"}
