An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2025-7673 and fix it if it is affected.\n\nWhat it is: CVE-2025-7673 is a critical memory corruption vulnerability in Zyxel VMG8825-T50K firmware, published on 16 Jul 2025. 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-2025-7673 in the wild and no public exploit code.\n\nAffected product: Zyxel VMG8825-T50K 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-2025-7673/ (Markdown: https://insights.sbomify.com/CVE-2025-7673/index.md)","id":"CVE-2025-7673","markdown":"https://insights.sbomify.com/CVE-2025-7673/index.md","name":"CVE-2025-7673","record":{"aliases":["GHSA-r3pp-h225-m34v"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Zyxel router firmware","requires_auth":"none","summary":"Unauthenticated attackers can cause denial of service or execute arbitrary code via a buffer overflow in the Zyxel VMG8825-T50K web server URL parser.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"emg3525-t50b_firmware","vendor":"zyxel"},{"product":"emg5523-t50b_firmware","vendor":"zyxel"},{"product":"emg5723-t50k_firmware","vendor":"zyxel"},{"product":"emg6726-b10a_firmware","vendor":"zyxel"},{"product":"ex3510-b0_firmware","vendor":"zyxel"},{"product":"ex5510-b0_firmware","vendor":"zyxel"},{"product":"vmg1312-t20b_firmware","vendor":"zyxel"},{"product":"vmg3625-t50b_firmware","vendor":"zyxel"},{"product":"vmg3925-b10b_firmware","vendor":"zyxel"},{"product":"vmg3925-b10c_firmware","vendor":"zyxel"},{"product":"vmg3927-b50a_firmware","vendor":"zyxel"},{"product":"vmg3927-b50b_firmware","vendor":"zyxel"},{"product":"vmg3927-b60a_firmware","vendor":"zyxel"},{"product":"vmg3927-t50k_firmware","vendor":"zyxel"},{"product":"vmg4005-b50b_firmware","vendor":"zyxel"},{"product":"vmg4927-b50a_firmware","vendor":"zyxel"},{"product":"vmg8623-t50b_firmware","vendor":"zyxel"},{"product":"vmg8825-b50a_firmware","vendor":"zyxel"},{"product":"vmg8825-b60a_firmware","vendor":"zyxel"},{"product":"vmg8825-bx0b_firmware","vendor":"zyxel"},{"product":"vmg8825-t50k_firmware","vendor":"zyxel"},{"product":"vmg8924-b10d_firmware","vendor":"zyxel"},{"product":"xmg3927-b50a_firmware","vendor":"zyxel"},{"product":"xmg8825-b50a_firmware","vendor":"zyxel"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","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-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A buffer overflow vulnerability in the URL parser of the zhttpd web server in Zyxel VMG8825-T50K firmware versions prior to V5.50(ABOM.5)C0 could allow an unauthenticated attacker to cause denial-of-service (DoS) conditions and potentially execute arbitrary code by sending a specially crafted HTTP request.","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 VMG8825-T50K firmware","id":"CVE-2025-7673","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"navify Monitoring API input validation","id":"CVE-2025-7674"},"packages":[],"prev":{"headline":"Stored-XSS possibility in Namo CrossEditor4","id":"CVE-2025-7672"},"products":["VMG8825-T50K firmware"],"published":"2025-07-16","related":[],"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":"total"},"state":"PUBLISHED","updated":"2026-02-26","vendors":["Zyxel"]},"summary":"Unauthenticated attackers can cause denial of service or execute arbitrary code via a buffer overflow in the Zyxel VMG8825-T50K web server URL parser.","url":"https://insights.sbomify.com/CVE-2025-7673/"}
