Title
Apache Camel: Camel-Netty-HTTP Security Constraint Bypass via Case-Sensitive Context-Path Matching
Summary
Improper Handling of Case Sensitivity vulnerability in Apache Camel Netty HTTP component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The camel-netty-http security constraint compared the request path against the configured context path using a case-sensitive match, while the routing that dispatches the request to the endpoint did not apply the same rule. The two comparisons therefore disagreed for any path whose case differed from the configured value. An external caller could alter the case of a character in a path segment so that the security constraint no longer recognised the path as protected, while the request still dispatched to the same endpoint. The result is that the constraint is skipped and the protected route is reached without satisfying it. No credential, prior access or special configuration is required beyond being able to send a request to the consumer. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. The constraint now matches the request path with the same case rules the dispatch uses, so the two can no longer disagree. For deployments that cannot upgrade immediately, place the authorization decision in front of the Camel consumer, for example in a reverse proxy that normalises the request path before forwarding.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
