{"identifier":"CVE-2026-102812","cve":{"id":"CVE-2026-102812","description":"A hard-coded\ncryptographic key vulnerability exists in the user-configuration backup\nmechanism of TP-Link RE305 V3 and Archer C7 V5. A fixed AES-128 key and\ninitialization vector are embedded in the firmware configuration-management\ncomponent. An attacker who obtains an affected configuration backup file may\nextract the cryptographic material from the firmware and use it to decrypt the\nbackup. \n\n\n\n\n\n\n\n\n\nSuccessful\nexploitation may disclose sensitive configuration information contained in a\nbackup file, including administrator passwords and Wi-Fi credentials.","published":"2026-10-27T18:17:29.517000+00:00","modified":"2026-10-28T14:47:54.847000+00:00","status":"Deferred","score":6.9,"severity":"MEDIUM","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","cvss_version":"4.0","affected":[],"weaknesses":["CWE-321"],"references":[{"url":"https://www.tp-link.com/en/support/download/archer-c7/v5/#Firmware","source":"f23511db-6c3e-4e32-a477-6aa17d310630"},{"url":"https://www.tp-link.com/en/support/download/re305/v3/#Firmware","source":"f23511db-6c3e-4e32-a477-6aa17d310630"},{"url":"https://www.tp-link.com/us/support/download/archer-c7/v5/#Firmware","source":"f23511db-6c3e-4e32-a477-6aa17d310630"},{"url":"https://www.tp-link.com/us/support/download/re305/v3/#Firmware","source":"f23511db-6c3e-4e32-a477-6aa17d310630"},{"url":"https://www.tp-link.com/us/support/faq/5362/","source":"f23511db-6c3e-4e32-a477-6aa17d310630"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV40":[{"source":"f23511db-6c3e-4e32-a477-6aa17d310630","type":"Secondary","cvssData":{"version":"4.0","vectorString":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","baseScore":6.9,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"NONE","userInteraction":"NONE","vulnConfidentialityImpact":"HIGH","vulnIntegrityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","exploitMaturity":"NOT_DEFINED","confidentialityRequirement":"NOT_DEFINED","integrityRequirement":"NOT_DEFINED","availabilityRequirement":"NOT_DEFINED","modifiedAttackVector":"NOT_DEFINED","modifiedAttackComplexity":"NOT_DEFINED","modifiedAttackRequirements":"NOT_DEFINED","modifiedPrivilegesRequired":"NOT_DEFINED","modifiedUserInteraction":"NOT_DEFINED","modifiedVulnConfidentialityImpact":"NOT_DEFINED","modifiedVulnIntegrityImpact":"NOT_DEFINED","modifiedVulnAvailabilityImpact":"NOT_DEFINED","modifiedSubConfidentialityImpact":"NOT_DEFINED","modifiedSubIntegrityImpact":"NOT_DEFINED","modifiedSubAvailabilityImpact":"NOT_DEFINED","Safety":"NOT_DEFINED","Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","valueDensity":"NOT_DEFINED","vulnerabilityResponseEffort":"NOT_DEFINED","providerUrgency":"NOT_DEFINED"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T17:25:47.583363+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.0012,"percentile":0.01829,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"www.tp-link.com","source_url":"https://www.tp-link.com/en/support/download/archer-c7/v5/#Firmware","investigate_url":"https://investigate.aeglixmind.com/#www.tp-link.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-102812","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-102812","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-102812","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
