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-2020-15892 in the wild and no public exploit code.\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-2020-15892/ (Markdown: https://insights.sbomify.com/CVE-2020-15892/index.md)","id":"CVE-2020-15892","markdown":"https://insights.sbomify.com/CVE-2020-15892/index.md","name":"CVE-2020-15892","record":{"aliases":["GHSA-mh3c-hpgm-9fqj"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"D-Link wireless access point","requires_auth":"none","summary":"A stack-based buffer overflow in the login handler allows remote attackers to execute arbitrary code by sending oversized login parameters.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dap-1520_firmware","vendor":"dlink"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","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-787","name":"Out-of-bounds Write"},{"id":"CWE-669","name":"Incorrect Resource Transfer Between Spheres"}],"description":"An issue was discovered in apply.cgi on D-Link DAP-1520 devices before 1.10b04Beta02. Whenever a user performs a login action from the web interface, the request values are being forwarded to the ssi binary. On the login page, the web interface restricts the password input field to a fixed length of 15 characters. The problem is that validation is being done on the client side, hence it can be bypassed. When an attacker manages to intercept the login request (POST based) and tampers with the vulnerable parameter (log_pass), to a larger length, the request will be forwarded to the webserver. This results in a stack-based buffer overflow. A few other POST variables, (transferred as part of the login request) are also vulnerable: html_response_page and log_user.","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 n/a","id":"CVE-2020-15892","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Command injection in n/a","id":"CVE-2020-15893"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2020-15890"},"products":["n/a"],"published":"2020-07-22","related":[{"cvss_score":8.7,"headline":"Tenda DAP-1520 storage check_dws_cookie stack-based overflow","id":"CVE-2025-4354","kev_date_added":null,"published":"2025-05-06"},{"cvss_score":8.7,"headline":"Tenda DAP-1520 api set_ws_action heap-based overflow","id":"CVE-2025-4355","kev_date_added":null,"published":"2025-05-06"},{"cvss_score":8.7,"headline":"Tenda DAP-1520 Authentication storage mod_graph_auth_uri_handler stack-based overflow","id":"CVE-2025-4356","kev_date_added":null,"published":"2025-05-06"},{"cvss_score":5.3,"headline":"Null dereference in n/a","id":"CVE-2024-36831","kev_date_added":null,"published":"2024-12-17"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"A stack-based buffer overflow in the login handler allows remote attackers to execute arbitrary code by sending oversized login parameters.","url":"https://insights.sbomify.com/CVE-2020-15892/"}
