Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-3715 exists.\n\nAffected product: Wavlink WL-WN579X3-C. 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-2026-3715/ (Markdown: https://insights.sbomify.com/CVE-2026-3715/index.md)","id":"CVE-2026-3715","markdown":"https://insights.sbomify.com/CVE-2026-3715/index.md","name":"CVE-2026-3715","record":{"aliases":["GHSA-7hf8-hqfw-77qp"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Wavlink router","requires_auth":"low_privilege","summary":"Remote attackers can trigger a stack-based buffer overflow in the firewall CGI script to execute arbitrary code on Wavlink routers.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"wl-wn579x3-c_firmware","vendor":"wavlink"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability was found in Wavlink WL-WN579X3-C 231124. This affects the function sub_40139C of the file /cgi-bin/firewall.cgi. Performing a manipulation of the argument del_flag results in stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been made public and could be used. Upgrading to version 20260226 is able to mitigate this issue. You should upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Wavlink WL-WN579X3-C firewall.cgi sub_40139C stack-based overflow","id":"CVE-2026-3715","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"Wavlink WL-WN579X3-C adm.cgi sub_401AD4 cross site scripting","id":"CVE-2026-3716"},"packages":[],"prev":{"headline":"OpenCart Incomplete Fix CVE-2024-36694 template.php save special elements used in a template engine","id":"CVE-2026-3714"},"products":["WL-WN579X3-C"],"published":"2026-03-08","related":[{"cvss_score":8.7,"headline":"Wavlink WL-WN579X3-C UPNP firewall.cgi sub_4019FC stack-based overflow","id":"CVE-2026-5004","kev_date_added":null,"published":"2026-03-28"},{"cvss_score":4.8,"headline":"Wavlink WL-WN579X3-C adm.cgi sub_401AD4 cross site scripting","id":"CVE-2026-3716","kev_date_added":null,"published":"2026-03-08"}],"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":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-11","vendors":["Wavlink"]},"summary":"Remote attackers can trigger a stack-based buffer overflow in the firewall CGI script to execute arbitrary code on Wavlink routers.","url":"https://insights.sbomify.com/CVE-2026-3715/"}
