- Insufficient validation of outbound header values may lead to request splitting or response splitting attacks in scenarios where attackers have sufficient control over outbound headers. Details Outbound trilliumhttp::HeaderValue and trilliumhttp::HeaderName can be constructed infallibly and were not checked for illegal bytes when sending requests from the client or responses from the server. Thus, if an attacker has sufficient control over header values (or names) in a request or response that they could inject \r\n sequences, they could get the client and server out of sync, and then pivot to gain control over other parts of requests or responses. (i.e. exfiltrating data from other requests, SSRF, etc.) Patches trillium-http = 0.3.12: If a header name is invalid in server response headers, the specific header and any associated values are omitted from network transmission. If a header value is invalid in server response headers, the individual header value is omitted from…
Recommended action: Upgrade to 0.3.12 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
