CVE-2024-7398

Status: ModifiedMedium (4.6)—

Concrete CMS versions 9 through 9.3.3 and versions below 8.5.19 are vulnerable to stored XSS in the calendar event addition feature because the calendar event name was not sanitized on output. Users or groups with permission to create event calendars can embed scripts, and users or groups with permission to modify event calendars can execute scripts. The Concrete CMS Security Team gave this vulnerability a CVSS v4 score of 4.6 with vector CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:A/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N Thank you, Yusuke Uchida for reporting. CNA updated this risk rank on 20 Jan 2025 by lowering the AC based on CVSS 4.0 documentation that access privileges should not be considered for AC)
