Summary
WIT SynApps Runtime through 1.4.11 contains a pre-authentication reflected cross-site scripting flaw (CWE-79). An unauthenticated attacker can inject and run arbitrary JavaScript by submitting a crafted LINK query parameter to the /System/Session-1 endpoint. Exploitation allows credential harvesting, manipulation of the login flow, access to browser-visible data, and same-origin requests to controller endpoints, including an origin-switch primitive against the internal controller in Cloud RIA scenarios. CVSS 4.0 scores it 5.1 (MEDIUM); CISA SSVC rates exploitation as PoC, not automatable, with partial technical impact, the flaw is not in KEV, and the references include an exploit link.
