Summary

HCLSoftware Connections versions from 7.0, 8.0 are affected by a cross-site scripting flaw (CWE-79). Input is not neutralized before it is placed in web pages, so injected script runs in the browser of a user. An attacker with low privileges needs a victim to interact with malicious content, which can expose cookie-based authentication credentials and compromise the user's account.
