{"cve":"CVE-2026-35903","nvd":{"published":"2026-04-27T19:16:52.817","modified":"2026-06-17T10:41:02.117","status":"Analyzed","description":"MERCURY MIPC252W IP camera 1.0.5 Build 230306 Rel.79931n contains an improper authentication vulnerability in the RTSP service. After successful Digest authentication in an initial DESCRIBE request, the device does not verify the Digest response parameter in subsequent RTSP requests within the same session. As a result, RTSP methods such as SETUP, PLAY, and TEARDOWN can be processed even when the Authorization header contains an empty or invalid response value, as long as the nonce and session identifier correspond to a previously authenticated session. This allows an attacker with network access to reuse session parameters and issue unauthorized RTSP control commands without computing a valid Digest response.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-287"],"references":["https://github.com/izxnfirh8148/CVE_REQUESTS_references/blob/main/MERCURY_MIPC252W/MERCURY_MIPC252W_4th/README.md","https://github.com/izxnfirh8148/CVE_REQUESTS_references/blob/main/MERCURY_MIPC252W/MERCURY_MIPC252W_4th/README.md"],"products":["mercurycom:mipc252w_firmware"],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-35903","score":0.00487,"percentile":0.41953,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
