Synopsis

The remote host is missing one or more security updates.

Description

The version of JetBrains TeamCity installed on the remote host is prior to 2025.11.0. It is, therefore, affected by multiple vulnerabilities as referenced in the advisory.

- In JetBrains TeamCity before 2025.11.0 Stored XSS was possible via session attribute (CVE-2025-67741)

- In JetBrains TeamCity before 2025.11.0 Reflected XSS was possible on VCS Root setup (CVE-2025-68165)
