TeamPlus Messenger: Code injection via crafted link
Summary
TeamPlus Messenger, a messaging client from Teamplus Technology, contains a code injection flaw (CWE-94). An unauthenticated attacker can send a crafted link that makes the client inject and run arbitrary JavaScript. After the user confirms a Windows security warning, the attacker can execute arbitrary code with the privileges of the logged-in user.
Affected
- TeamPlus Messenger 16.8.0 to 17.0.6 (according to TWCERT/CC and the CVE record)
Fixed in
- TeamPlus Messenger 17.0.7 and later (named as the solution by TWCERT/CC)
- Vendor-specific security advisory or changelog entry for this CVE: Unknown.
Workaround
- No vendor-published workaround found: Unknown.
- Until patched: block or warn on links from external senders, and do not allow users to click through Windows security warnings for links in messenger chats.
Exploitation
- No confirmed exploitation in the wild found.
- CISA SSVC assessment: Exploitation none, Automatable no, Technical Impact total.
- No public proof of concept found; this does not prove that none exists.
- EPSS 0.00584 (Vulners).
Our recommendation
- Check whether TeamPlus Messenger is in use and on which systems, especially Windows clients.
- Upgrade affected clients to 17.0.7 or later. Confirm the upgrade procedure with Teamplus first, because the vendor notes significant changes and that old versions must be removed before installing the new one.
- Until the upgrade is complete, apply the workarounds above and brief staff on not trusting links in messenger chats.
- Monitor for unusual script or process activity started from the messenger client.
