GHSA-vq4p-pchp-6g6v: Apache Camel Missing Header Out Filter Leads to Potential Bypass/Injection Vulnerability
Bypass/Injection vulnerability in Apache Camel in Camel-Undertow component under particular conditions.
This issue affects Apache Camel: from 4.10.0 before 4.10.3, from 4.8.0 before 4.8.6.
Users are recommended to upgrade to version 4.10.3 for 4.10.x LTS and 4.8.6 for 4.8.x LTS.
Camel undertow component is vulnerable to Camel message header injection, in particular the custom header filter strategy used by the component only filter the “out” direction, while it doesn’t filter the “in” direction.
This allows an attacker to include Camel specific headers that for some Camel components can alter the behaviour such as the camel-bean component, or the camel-exec component.
Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
