{"cve":"CVE-2020-10713","nvd":{"published":"2020-07-30T13:15:10.940","modified":"2026-06-17T02:48:18.150","status":"Modified","description":"A flaw was found in grub2, prior to version 2.06. An attacker may use the GRUB 2 flaw to hijack and tamper the GRUB verification process. This flaw also allows the bypass of Secure Boot protections. In order to load an untrusted or modified kernel, an attacker would first need to establish access to the system such as gaining physical access, obtain the ability to alter a pxe-boot network, or have remote access to a networked system with root access. With this access, an attacker could then craft a string to cause a buffer overflow by injecting a malicious payload that leads to arbitrary code execution within GRUB. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","score":8.2},"cwes":["CWE-120"],"references":["http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00016.html","http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00017.html","http://www.openwall.com/lists/oss-security/2020/07/29/3","https://bugzilla.redhat.com/show_bug.cgi?id=1825243","https://cve.openeuler.org/#/CVEInfo/CVE-2020-10713"],"products":["debian:debian_linux","gnu:grub2","opensuse:leap","vmware:photon_os"],"source":"nvd","synced_at":"2026-10-19T21:06:22.076270124+00:00"},"epss":{"cve":"CVE-2020-10713","score":0.01711,"percentile":0.77361,"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).
