{"id":"CVE-2025-34433","state":"PUBLISHED","title":"AVideo < 20.1 Unauthenticated RCE via Predictable Installation Salt","description":"AVideo versions 14.3.1 prior to 20.1 contain an unauthenticated remote code execution vulnerability caused by predictable generation of an installation salt using PHP uniqid(). The installation timestamp is exposed via a public endpoint, and a derived hash identifier is accessible through unauthenticated API responses, allowing attackers to brute-force the remaining entropy. The recovered salt can then be used to encrypt a malicious payload supplied to a notification API endpoint that evaluates attacker-controlled input, resulting in arbitrary code execution as the web server user.","publishedAt":"2025-12-19T15:37:39.775Z","updatedAt":"2026-06-23T16:13:27.861Z","severity":{"score":9.3,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["World Wide Broadcast Network AVideo"],"affected":[{"vendor":"World Wide Broadcast Network","product":"AVideo","defaultStatus":"unaffected","versions":[{"version":"14.3.1","status":"affected","lessThan":"20.1","versionType":"custom"}]}],"references":["https://github.com/WWBN/AVideo/commit/4a53ab2","https://github.com/WWBN/AVideo/commit/a2bdbff","https://www.vulncheck.com/advisories/avideo-unauthenticated-rce-via-predictable-installation-salt","https://chocapikk.com/posts/2025/avideo-security-vulnerabilities/"],"weaknesses":["CWE-94"],"ingestedAt":"2026-10-29T20:09:03.054Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/34xxx/CVE-2025-34433.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-34433","state":"PUBLISHED","datePublished":"2025-12-19T15:37:39.775Z","dateUpdated":"2026-06-23T16:13:27.861Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2025-04-15T19:15:22.601Z"},"containers":{"cna":{"title":"AVideo < 20.1 Unauthenticated RCE via Predictable Installation Salt","descriptions":[{"lang":"en","value":"AVideo versions 14.3.1 prior to 20.1 contain an unauthenticated remote code execution vulnerability caused by predictable generation of an installation salt using PHP uniqid().
