CVE-2022-43695: Concretecms Concrete CMS

Medium severity, CVSS 4.8. EPSS: 0.6% chance of exploitation in the next 30 days.

Concrete CMS (formerly concrete5) below 8.5.10 and between 9.0.0 and 9.1.2 is vulnerable to Stored Cross-Site Scripting (XSS) in dashboard/system/express/entities/associations because Concrete CMS allows association with an entity name that doesn’t exist or, if it does exist, contains XSS since it was not properly sanitized. Remediate by updating to Concrete CMS 9.1.3+ or 8.5.10+.

Affected products

• Concretecms Concrete CMS: before 8.5.10 (fixed in 8.5.10); from 9.0.0, up to and including 9.1.2
