A content spoofing vulnerability exists in multiple WSO2 products due to improper error message handling. Under certain conditions, error messages are passed through URL parameters without validation, allowing malicious actors to inject arbitrary content into the UI.
By exploiting this vulnerability, attackers can manipulate browser-displayed error messages, enabling social engineering attacks through deceptive or misleading content.
The user interface (UI) does not properly represent critical information to the user, allowing the information - or its source - to be obscured or spoofed. This is often a component in phishing attacks.
If an attacker can cause the UI to display erroneous data, or to otherwise convince the user to display information that appears to come from a trusted source, then the attacker could trick the user into performing the wrong action. This is often a component in phishing attacks, but other kinds of problems exist. For example, if the UI is used to monitor the security state of a system or network, then omitting or obscuring an important indicator could prevent the user from detecting and reacting to a security-critical event. UI misrepresentation can take many forms:
