A stored cross-site scripting (XSS) vulnerability exists in the Classic Web Client due to insufficient sanitization of HTML content in ICS files. When a user views an e-mail message containing a malicious ICS entry, its embedded JavaScript executes via an ontoggle event inside a <details> tag. This allows an attacker to run arbitrary JavaScript within the victim's session, potentially leading to unauthorized actions such as setting e-mail filters to redirect messages to an attacker-controlled address. As a result, an attacker can perform unauthorized actions on the victim's account, including e-mail redirection and data exfiltration."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://wiki.zimbra.com/wiki/Security_Center"},{"url":"https://wiki.zimbra.com/wiki/Zimbra_Releases/10.1.5#Security_Fixes"},{"url":"https://wiki.zimbra.com/wiki/Zimbra_Releases/10.0.13#Security_Fixes"},{"url":"https://wiki.zimbra.com/wiki/Zimbra_Releases/9.0.0/P44#Security_Fixes"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"metrics":[{"cvssV3_1":{"scope":"CHANGED","version":"3.1","baseScore":5.4,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","integrityImpact":"LOW","userInteraction":"REQUIRED","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"LOW","confidentialityImpact":"LOW"}},{"other":{"type":"ssvc","content":{"id":"CVE-2025-27915","role":"CISA Coordinator","options":[{"Exploitation":"active"},{"Automatable":"no"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2025-10-07T03:55:56.855156Z"}}},{"other":{"type":"kev","content":{"dateAdded":"2025-10-07","reference":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2025-27915"}}}],"references":[{"url":"https://strikeready.com/blog/0day-ics-attack-in-the-wild/"},{"url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2025-27915"}],"problemTypes":[{"descriptions":[{"lang":"en","type":"CWE","cweId":"CWE-79","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')"}]}],"timeline":[{"time":"2025-10-07T00:00:00.000Z","lang":"en","value":"CVE-2025-27915 added to CISA KEV"}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-02-26T19:09:35.780Z"}}]},"dataVersion":"5.2"}
