Attackers can exploit the temporary-download endpoint's insufficient Content-Security-Policy sandbox to execute scripts when the attachment is opened, enabling theft of the victim's credentials and mailbox contents. Proofpoint Threat Research has observed exploitation in the wild as a credential and mailbox stealer.","cvssScore":8.2,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N","cwes":["CWE-79","CWE-83"],"vendors":[],"products":[],"references":[{"url":"https://gfi.ai/resource/kerioconnect-product-releases/","tags":[]},{"url":"https://www.vulncheck.com/advisories/gfi-kerioconnect-8p2-stored-xss-via-svg-attachment","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
