{"id":"CVE-2026-49322","state":"PUBLISHED","title":"Indian Scout Bobber 2025 Infotainment-to-WCM weak authentication allows recovery of user PIN from observed exchange","description":"Weak authentication in the Wireless Control Module (WCM) of the Indian Motorcycle Scout Bobber + Tech 2025 model year allows an adjacent-network attacker with read access to the in-vehicle network to recover the user-set unlock PIN by passively observing a single PIN authentication exchange. The Infotainment Digital Round display computes its response using a non-cryptographic operation rather than a cryptographic challenge-response, so the PIN is mathematically derivable from one captured exchange, defeating the motorcycle's primary user-authentication control. Specific protocol details have been withheld pending vendor remediation.","publishedAt":"2026-05-29T07:29:55.546Z","updatedAt":"2026-06-27T08:46:27.117Z","severity":{"score":4.1,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:P/AC:L/AT:P/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","source":"ASRG"},"assigner":"ASRG","products":["Indian Motorcycle Scout Bobber + Tech"],"affected":[{"vendor":"Indian Motorcycle","product":"Scout Bobber + Tech","defaultStatus":"unknown","versions":[{"version":"2025","status":"affected","versionType":"model-year"}],"platforms":["OEM Motorcycle"],"modules":["Wireless Control Module (WCM)","Infotainment / Digital Round"]}],"references":["https://www.asrg.io/security-advisories/cve-2026-49322-indian-scout-infotainment-wcm-weak-authentication"],"weaknesses":["CWE-1390","CWE-327","CWE-294"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/49xxx/CVE-2026-49322.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-49322","state":"PUBLISHED","datePublished":"2026-05-29T07:29:55.546Z","dateUpdated":"2026-06-27T08:46:27.117Z","assignerShortName":"ASRG","assignerOrgId":"c15abc07-96a9-4d11-a503-5d621bfe42ba","dateReserved":"2026-05-29T07:26:43.199Z"},"containers":{"cna":{"title":"Indian Scout Bobber 2025 Infotainment-to-WCM weak authentication allows recovery of user PIN from observed exchange","descriptions":[{"lang":"en","value":"Weak authentication in the Wireless Control Module (WCM) of the Indian Motorcycle Scout Bobber + Tech 2025 model year allows an adjacent-network attacker with read access to the in-vehicle network to recover the user-set unlock PIN by passively observing a single PIN authentication exchange.
