{"id":"CVE-2025-15683","state":"PUBLISHED","title":"Multiple Unauthenticated Denial-of-Service Conditions","description":"TBEA TLogger V2.1.0.0B0.0.0.0 contains multiple unauthenticated denial-of-service vulnerabilities in its web server. An unauthenticated remote attacker can invoke specific HTTP endpoints to reboot or reset the device, clear application data, or terminate the web server through a segmentation fault. In addition, multiple action endpoints process attacker-controlled parameters using unsafe string operations such as sprintf() and strcat() without adequate bounds checking, allowing crafted input to trigger buffer overflows and crash the web server. The affected endpoints include onRestart, onReset, ClearData, uploadInvFile, getIndiaRPData, YearCaparity, TotalfaultData, recordData, InvHistoryData, CollectHistoryData, InvFaultData, GetPortTableByParm, and UpdatePortConfig.","publishedAt":"2026-08-10T19:38:57.641Z","updatedAt":"2026-08-12T18:17:21.333Z","severity":{"score":8.8,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N","source":"CyberDanube"},"assigner":"CyberDanube","products":["TBEA TBEA TLogger (TBEA Communication Box 3rd Generation)"],"affected":[{"vendor":"TBEA","product":"TBEA TLogger (TBEA Communication Box 3rd Generation)","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"V2.1.0.0B0.0.0.0","versionType":"custom"}]}],"references":["https://en.tbea.com/about.html"],"weaknesses":["CWE-306","CWE-121"],"ingestedAt":"2026-10-29T20:08:31.050Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/15xxx/CVE-2025-15683.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-15683","state":"PUBLISHED","datePublished":"2026-08-10T19:38:57.641Z","dateUpdated":"2026-08-12T18:17:21.333Z","assignerShortName":"CyberDanube","assignerOrgId":"7d092a75-6bbd-48c6-a15a-0297458009bc","dateReserved":"2026-08-04T11:34:49.423Z"},"containers":{"cna":{"title":"Multiple Unauthenticated Denial-of-Service Conditions","descriptions":[{"lang":"en","value":"TBEA TLogger V2.1.0.0B0.0.0.0 contains multiple unauthenticated denial-of-service vulnerabilities in its web server.
