Attackers can guess default account names such as Admin or sftp_user and submit a forged username cookie to satisfy the login check in checkLogin (libwebcmn.so) and networkDiag.cgi, chaining into root command execution.","provenance":"source","from":"NVD"},"summary":{"text":"Sunhillo SureLine versions before 9.1.5 contain an authentication bypass in its web session handling, specifically in the checkLogin function of libwebcmn.so and the networkDiag.cgi component, where session cookies are trusted without random identifiers or integrity protection. An unauthenticated remote attacker can exploit this by guessing default account names such as Admin or sftp_user and submitting a forged username-only cookie to impersonate that user, which can chain into root command execution.","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-29T07:22:48Z"},"cvss":{"score":9.1,"severity":"CRITICAL","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","provenance":"source","from":"NVD"},"epss":{"score":0.01319,"percentile":0.70836,"date":"2026-10-31","provenance":"source"},"kev":null,"vulncheckKev":null,"exploited":false,"otx":null,"cwes":[{"id":"CWE-565","name":"Reliance on Cookies without Validation and Integrity Checking"}],"references":[{"url":"https://www.sunhillo.com/product/sureline/","tags":[]},{"url":"https://www.vulncheck.com/advisories/sunhillo-sureline-authentication-bypass-via-session-cookie","tags":[]}],"techniques":[],"reports":[],"affected":[],"advisories":[],"euvd":{"id":"EUVD-2026-111360","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-111360","exploited":false,"exploitedSince":null,"provenance":"source"},"exploits":[],"exploitSources":null,"exploitRefs":[],"flow":[],"timeline":[{"date":"2026-10-27","kind":"published","label":"Published (NVD)","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-112352","provenance":"source"}],"speed":{"daysToPublicExploit":null,"firstExploitFrom":null,"daysToKev":null},"priority":{"score":20.5,"factors":[{"name":"In a KEV catalog","points":0.0,"detail":"not listed"},{"name":"Recent KEV listing","points":0.0,"detail":"not listed"},{"name":"Known ransomware use","points":0.0,"detail":"not known"},{"name":"EPSS percentile","points":14.17,"detail":"percentile 0.7084"},{"name":"Named in threat reports","points":0.0,"detail":"0 reports"},{"name":"Public exploit code","points":0.0,"detail":"none found"},{"name":"Mentioned in OTX pulses","points":0.0,"detail":"0 pulses"},{"name":"CVSS severity","points":6.37,"detail":"base score 9.1"},{"name":"End-of-life product","points":0.0,"detail":"supported or unknown"}]}}
