This flaw allows an attacker who can send a specially crafted request to the router\u2019s configuration interface to overwrite memory on the device. If exploited, the attacker could gain arbitrary code execution, compromising the integrity and confidentiality of the router and potentially the devices connected to it.", "risk_and_exploitability": "The CVSS score of 9.8 indicates critical severity, while the EPSS score of less than 1% suggests low available exploitation probability at the time of analysis. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog, so no confirmed exploits are publicly known. Nonetheless, the attack vector is inferred to be remote via the router\u2019s HTTP management interface; an attacker could construct a request without authentication if the interface is exposed to the public network or accessed by an untrusted internal user. Given its high impact, the potential for remote code execution remains a top concern for any organization still running the affected firmware."}}}}, "created": "2026-03-04T21:04:33.353541+00:00", "title": "Buffer Overflow in Tenda AC15 Configuration API Enabling Potential Remote Code Execution", "updated": "2026-04-16T14:15:28.817382+00:00", "vendors": ["tenda", "tenda$PRODUCT$ac15"]}
