{"id":"CVE-2026-63587","state":"PUBLISHED","title":"SMS Password Authorization Bypass via Failed Attempt Counter","description":"The SMS control function of IE-SR-2TX-WL-4G devices can require a password for SMS commands via the 'Enable Password Authorization' setting. The device increments a retry counter on each failed SMS password attempt; after 5 consecutive failed attempts, SMS password authorization is automatically disabled. An unauthenticated remote attacker who is able to send SMS messages to the device can deliberately trigger this by submitting 5 or more invalid passwords, after which subsequent SMS commands are executed without requiring a password, resulting in potential limited configuration tampering, limited information leakage and potentially full loss of availability.","publishedAt":"2026-08-25T08:55:12.442Z","updatedAt":"2026-08-27T15:04:29.396Z","severity":{"score":8.8,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N","source":"CERTVDE"},"assigner":"CERTVDE","products":["Weidmueller Interface IE-SR-2TX-WL-4G-EU","Weidmueller Interface IE-SR-2TX-WL-4G-US-V"],"affected":[{"vendor":"Weidmueller Interface","product":"IE-SR-2TX-WL-4G-EU","defaultStatus":"unaffected","versions":[{"version":"1.67","status":"affected","lessThan":"1.74","versionType":"semver"}]},{"vendor":"Weidmueller Interface","product":"IE-SR-2TX-WL-4G-US-V","defaultStatus":"unaffected","versions":[{"version":"1.67","status":"affected","lessThan":"1.74","versionType":"semver"}]}],"references":["https://www.certvde.com/en/advisories/VDE-2026-083/"],"weaknesses":["CWE-288"],"ingestedAt":"2026-10-29T20:12:41.951Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/63xxx/CVE-2026-63587.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-63587","state":"PUBLISHED","datePublished":"2026-08-25T08:55:12.442Z","dateUpdated":"2026-08-27T15:04:29.396Z","assignerShortName":"CERTVDE","assignerOrgId":"270ccfa6-a436-4e77-922e-914ec3a9685c","dateReserved":"2026-07-17T06:47:50.712Z"},"containers":{"cna":{"title":"SMS Password Authorization Bypass via Failed Attempt Counter","descriptions":[{"lang":"en","value":"The SMS control function of IE-SR-2TX-WL-4G devices can require a password for SMS commands via the 'Enable Password Authorization' setting.
