Element Android is an Android Matrix Client. Element Android version 1.4.3 through 1.6.10 is vulnerable to intent redirection, allowing a third-party malicious application to start any internal activity by passing some extra parameters. Possible impact includes making Element Android display an arbitrary web page, executing arbitrary JavaScript; bypassing PIN code protection; and account takeover by spawning a login screen to send credentials to an arbitrary home server. This issue is fixed in Element Android 1.6.12. There is no known workaround to mitigate the issue.
The product establishes a communication channel to (or from) an endpoint for privileged or protected operations, but it does not properly ensure that it is communicating with the correct endpoint.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Element | Element | 1.4.3 (including) | 1.6.12 (excluding) |
Attackers might be able to spoof the intended endpoint from a different system or process, thus gaining the same level of access as the intended endpoint. While this issue frequently involves authentication between network-based clients and servers, other types of communication channels and endpoints can have this weakness.
