Description

Concrete CMS version 9 prior to 9.2.8 and previous versions prior to 8.5.16 are vulnerable to Stored XSS in the Search Field. Prior to the fix, stored XSS could be executed by an administrator changing a filter to which a rogue administrator had previously added malicious code. The Concrete CMS security team gave this vulnerability a CVSS v3.1 score of 3.1 with a vector of AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:L/A:L https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator . Thanks Alexey Solovyev for reporting
