An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-22915 and fix it if it is affected.\n\nWhat it is: CVE-2023-22915 is a high-severity memory corruption vulnerability in Zyxel USG FLEX 50(W) firmware, published on 24 Apr 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-22915 in the wild and no public exploit code.\n\nAffected product: Zyxel USG FLEX 50(W) 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-2023-22915/ (Markdown: https://insights.sbomify.com/CVE-2023-22915/index.md)","id":"CVE-2023-22915","markdown":"https://insights.sbomify.com/CVE-2023-22915/index.md","name":"CVE-2023-22915","record":{"aliases":["GHSA-qm4q-mvq2-gj2r"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Zyxel USG/VPN firmware","requires_auth":"none","summary":"Remote unauthenticated attackers can cause denial of service via crafted HTTP requests if Facebook WiFi is enabled on affected Zyxel USG and VPN devices.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"usg_20w-vpn_firmware","vendor":"zyxel"},{"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":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A buffer overflow vulnerability in the “fbwifi_forward.cgi” CGI program of Zyxel USG FLEX series firmware versions 4.50 through 5.35, USG FLEX 50(W) firmware versions 4.30 through 5.35, USG20(W)-VPN firmware versions 4.30 through 5.35, and VPN series firmware versions 4.30 through 5.35, which could allow a remote unauthenticated attacker to cause DoS conditions by sending a crafted HTTP request if the Facebook WiFi function were enabled 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":"Memory corruption in USG FLEX 50(W) firmware","id":"CVE-2023-22915","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Other in ATP series firmware","id":"CVE-2023-22916"},"packages":[],"prev":{"headline":"Path traversal in USG FLEX series firmware","id":"CVE-2023-22914"},"products":["USG FLEX 50(W) firmware","USG FLEX series firmware","USG20(W)-VPN firmware","VPN series firmware"],"published":"2023-04-24","related":[{"cvss_score":8.8,"headline":"Command injection in ATP series firmware","id":"CVE-2023-28767","kev_date_added":null,"published":"2023-07-17"},{"cvss_score":8.8,"headline":"Command injection in ATP series firmware","id":"CVE-2023-33011","kev_date_added":null,"published":"2023-07-17"},{"cvss_score":8.8,"headline":"Command injection in ATP series firmware","id":"CVE-2023-33012","kev_date_added":null,"published":"2023-07-17"},{"cvss_score":8,"headline":"Command injection in ATP series firmware","id":"CVE-2023-34138","kev_date_added":null,"published":"2023-07-17"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-12","vendors":["Zyxel"]},"summary":"Remote unauthenticated attackers can cause denial of service via crafted HTTP requests if Facebook WiFi is enabled on affected Zyxel USG and VPN devices.","url":"https://insights.sbomify.com/CVE-2023-22915/"}
