The vulnerability is due to the presence of a hidden command in the affected software. An attacker could exploit this vulnerability by connecting to an affected device via the console, forcing the device into ROMMON mode, and writing a malicious pattern to a specific memory address on the device. A successful exploit could allow the attacker to bypass signature validation checks by Cisco Secure Boot technology and load a compromised software image on the affected device. A compromised software image is any software image that has not been digitally signed by Cisco.", "severity": [ { "type": "CVSS_V3", "score": "CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H" } ], "affected": [], "references": [ { "type": "ADVISORY", "url": "https://nvd.nist.gov/vuln/detail/CVE-2018-15370" }, { "type": "WEB", "url": "https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-catalyst6800" }, { "type": "WEB", "url": "http://www.securityfocus.com/bid/105412" } ], "database_specific": { "cwe_ids": [], "severity": "MODERATE", "github_reviewed": false, "github_reviewed_at": null, "nvd_published_at": "2018-10-05T14:29:00Z" } }
