An attacker with physical access to the vehicle can bypass the encryption of log dumps on the In-Vehicle Infotainment (IVI) unit's storage. This allows the attacker to access and read system logs containing sensitive data, including personally identifiable information (PII) and location data.\n\nThis vulnerability was introduced in a patch intended to fix CVE-2024-54728.","published_at":"2025-08-09T12:42:29.150000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":5.1,"cvss_v4_vector":"CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:L/SI:N/SA:N/AU:Y/V:D/RE:H","cvss_v4_severity":"MEDIUM","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-656"],"nvd_references":["https://asrg.io/security-advisories/cve-2025-7020/"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:28:27.573294Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"P","value_label":"Physical"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"N","value_label":"None"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"N","value_label":"None"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"L","value_label":"Low"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"},{"metric":"AU","name":"AU","value":"Y","value_label":"Y"},{"metric":"V","name":"V","value":"D","value_label":"D"},{"metric":"RE","name":"RE","value":"H","value_label":"High"}]},"affected":[{"vendor_slug":"byd","vendor_name":"BYD","product_slug":"dilink-os","product_name":"DiLink OS","version_start":"13.1.32.2307211.1","version_start_inclusive":true,"version_end":"13.1.32.2307211.1","version_end_inclusive":true,"cpe23_uri":"cve5:byd:dilink-os:13.1.32.2307211.1:13.1.32.2307211.1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://asrg.io/security-advisories/cve-2025-7020/","source_type":"VENDOR_ADVISORY","tags":["advisory"]}],"timeline":[{"type":"published","at":"2025-08-09T12:42:29.150000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:49:45.838521Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:49:45.838521Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:49:45.838521Z","label":"CVSS score revised","source":"cvelistv5"}]}
