The issue stems from improper handling of executable trust and absence of integrity checks in the watchdog logic.","publishedAt":"2025-08-22T00:00:00.000Z","updatedAt":"2025-08-22T18:36:28.102Z","severity":{"score":7.3,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L","source":"CISA-ADP"},"assigner":"mitre","products":["n/a n/a"],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":["https://www.dlink.com/en/security-bulletin/","https://legacy.us.dlink.com/pages/product.aspx?id=f9c0458bfe7b4ff3bf7fad1cf6fcc9a1","https://cybermaya.in/posts/Post-42/"],"weaknesses":["CWE-494","CWE-306","CWE-269"],"ingestedAt":"2026-10-29T20:09:31.862Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/55xxx/CVE-2025-55581.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-55581","state":"PUBLISHED","datePublished":"2025-08-22T00:00:00.000Z","dateUpdated":"2025-08-22T18:36:28.102Z","assignerShortName":"mitre","assignerOrgId":"8254265b-2729-46b6-b9e3-3dfca2d5bfca","dateReserved":"2025-08-13T00:00:00.000Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"D-Link DCS-825L firmware version 1.08.01 and possibly prior versions contain an insecure implementation in the mydlink-watch-dog.sh script.
