{"cve":"CVE-2014-125122","nvd":{"published":"2025-07-31T15:15:34.620","modified":"2026-06-17T00:04:30.327","status":"Deferred","description":"A stack-based buffer overflow vulnerability exists in the tmUnblock.cgi endpoint of the Linksys WRT120N wireless router. The vulnerability is triggered by sending a specially crafted HTTP POST request with an overly long TM_Block_URL parameter to the endpoint. By exploiting this flaw, an unauthenticated remote attacker can overwrite memory in a controlled manner, enabling them to temporarily reset the administrator password of the device to a blank value. This grants unauthorized access to the router’s web management interface without requiring valid credentials.","cvss_v4":{"vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","score":5.3},"cvss_v3":null,"cwes":["CWE-121"],"references":["https://raw.githubusercontent.com/rapid7/metasploit-framework/master/modules/auxiliary/admin/http/linksys_tmunblock_admin_reset_bof.rb","https://web.archive.org/web/20210424073058/http://www.devttys0.com/2014/02/wrt120n-fprintf-stack-overflow/","https://www.exploit-db.com/exploits/31758","https://www.vulncheck.com/advisories/linksys-wrt120n-stack-based-buffer-overflow-admin-password-reset"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:05:46.678065081+00:00"},"epss":{"cve":"CVE-2014-125122","score":0.01158,"percentile":0.67089,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
