Smack allows the bypass of TLS protections
CVE-2016-10027 · GHSA-66pq-hqv5-228g
- Affected
- Maven org.igniterealtime.smack:smack-core < 4.1.9
- Fixed in
- 4.1.9· Vendor fix available
- Issue
- Race condition in the XMPP library in Smack before 4.1.9, when the SecurityMode.required TLS setting has been set, allows man-in-the-middle attackers to bypass TLS protections and trigger use of cleartext for client authentication by stripping the "starttls" feature from a server response.
Recommended action: Upgrade to 4.1.9 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
