NOTE: the Supplier's position is that the instance of CWE-1394 is not a vulnerability because customers \"are supposed to enable\" a non-default option that eliminates the weakness. However, that non-default option can disrupt functionality as shown in the \"Managing FortiGates with private data encryption\" document, and is therefore intentionally not a default option.","provenance":"source","from":"CVE.org"},"summary":null,"cvss":{"score":3.2,"severity":"LOW","version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N","provenance":"source","from":"CVE.org CNA"},"epss":{"score":0.00113,"percentile":0.01431,"date":"2026-10-30","provenance":"source"},"kev":null,"vulncheckKev":{"dateAdded":"2026-02-05","exploitedFirstSeen":"2026-02-05","ransomware":false,"evidence":[{"url":"https://www.cve.org/CVERecord?id=CVE-2026-25815","date":"2026-02-05"}],"evidenceTotal":1,"provenance":"source"},"exploited":true,"otx":{"pulseCount":0,"pulses":[],"provenance":"machine"},"cwes":[{"id":"CWE-1394","name":"Use of Default Cryptographic Key"}],"references":[{"url":"https://www.cert.at/en/blog/2026/1/threat-actors-use-forticloud-to-collect-ldap-connection-passwords","tags":[]},{"url":"https://docs.fortinet.com/document/fortimanager/7.6.6/administration-guide/30332/managing-fortigates-with-private-data-encryption","tags":[]}],"techniques":[],"reports":[],"affected":[],"advisories":[],"euvd":{"id":"EUVD-2026-5525","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-5525","exploited":false,"exploitedSince":null,"provenance":"source"},"exploits":[],"exploitSources":null,"exploitRefs":[],"flow":[],"timeline":[{"date":"2026-02-05","kind":"published","label":"Published (CVE.org)","url":"https://www.cve.org/CVERecord?id=CVE-2026-25815","provenance":"source"},{"date":"2026-02-05","kind":"exploited-reported","label":"Exploitation first reported (VulnCheck KEV evidence)","url":"https://www.cve.org/CVERecord?id=CVE-2026-25815","provenance":"source"}],"speed":{"daysToPublicExploit":null,"firstExploitFrom":null,"daysToKev":null},"priority":{"score":42.5,"factors":[{"name":"In a KEV catalog","points":35.0,"detail":"listed in VulnCheck KEV"},{"name":"Recent KEV listing","points":5.0,"detail":"added 268 days ago"},{"name":"Known ransomware use","points":0.0,"detail":"not known"},{"name":"EPSS percentile","points":0.29,"detail":"percentile 0.0143"},{"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":2.24,"detail":"base score 3.2"},{"name":"End-of-life product","points":0.0,"detail":"supported or unknown"}]}}
