An attacker with network access to the SSL-VPN, without needing credentials, can potentially bypass MFA by logging in with the alternative account name, provided MFA is not enforced consistently across both forms.","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-31T13:00:00Z"},"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":"CISA ADP Vulnrichment"},"epss":{"score":0.00487,"percentile":0.41908,"date":"2026-10-30","provenance":"source"},"kev":null,"vulncheckKev":{"dateAdded":"2026-05-19","exploitedFirstSeen":"2026-05-19","ransomware":true,"evidence":[{"url":"https://reliaquest.com/blog/threat-spotlight-vpn-exploitation-when-patched-doesnt-mean-protected/","date":"2026-05-19"},{"url":"https://www.cyfirma.com/research/tracking-ransomware-may-2026/","date":"2026-06-08"}],"evidenceTotal":2,"provenance":"source"},"exploited":true,"otx":{"pulseCount":2,"pulses":[{"name":"EbeeMay2026 Pt5","url":"https://otx.alienvault.com/pulse/6a1814b55e1559397600e7f7","created":"2026-05-28"},{"name":"VPN Exploitation When Patched Doesn't Mean Protected","url":"https://otx.alienvault.com/pulse/6a1450e73297d6df2985c994","created":"2026-05-25"}],"provenance":"machine"},"cwes":[{"id":"CWE-305","name":"Authentication Bypass by Primary Weakness"}],"references":[{"url":"https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2025-0001","tags":["vendor-advisory"]}],"techniques":[],"reports":[],"affected":[],"advisories":[],"euvd":{"id":"EUVD-2024-51116","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2024-51116","exploited":false,"exploitedSince":null,"provenance":"source"},"exploits":[],"exploitSources":null,"exploitRefs":[],"flow":[],"timeline":[{"date":"2025-01-09","kind":"published","label":"Published (CVE.org)","url":"https://www.cve.org/CVERecord?id=CVE-2024-12802","provenance":"source"},{"date":"2026-05-19","kind":"exploited-reported","label":"Exploitation first reported (VulnCheck KEV evidence)","url":"https://reliaquest.com/blog/threat-spotlight-vpn-exploitation-when-patched-doesnt-mean-protected/","provenance":"source"}],"speed":{"daysToPublicExploit":null,"firstExploitFrom":null,"daysToKev":null},"priority":{"score":65.8,"factors":[{"name":"In a KEV catalog","points":35.0,"detail":"listed in VulnCheck KEV"},{"name":"Recent KEV listing","points":5.0,"detail":"added 165 days ago"},{"name":"Known ransomware use","points":10.0,"detail":"VulnCheck KEV: Known"},{"name":"EPSS percentile","points":8.38,"detail":"percentile 0.4191"},{"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":1.08,"detail":"2 pulses"},{"name":"CVSS severity","points":6.37,"detail":"base score 9.1"},{"name":"End-of-life product","points":0.0,"detail":"supported or unknown"}]}}
