Overview

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due several issues in the loading of untrusted configurations. An attacker can cause excessive resource consumption by manipulating the configuration data or introducing unexpected usage patterns. Users affected by this issue are recommended to upgrade to the 2.x version line org.apache.commons:commons-configuration2, which fixes these issues.

Note: This is only exploitable if the application is configured to load untrusted configurations.

Remediation

There is no fixed version for commons-configuration:commons-configuration.

Overview

org.eclipse.jetty:jetty-server is a lightweight highly scalable java based web server and servlet engine.

Affected versions of this package are vulnerable to Improper Validation of Consistency within Input through ComplianceUtils.verify(HttpURI, HttpFields, HttpCompliance, ComplianceViolation.Listener) in jetty-core/jetty-http/src/main/java/org/eclipse/jetty/http/ComplianceUtils.java. An attacker can bypass host consistency checks by sending a request whose :authority pseudo-header and Host header name different hosts, causing Jetty to accept the request and expose conflicting host identities to different code paths. This lets attacker-controlled host information survive inside the request, so logic that relies on Request.getServerName() or the URI authority can see one host while code reading the raw Host header sees another. In deployments that use host-based routing, ACLs, redirects, or tenant isolation, this can lead to incorrect request handling, host-based access control bypass, and attacker-influenced URL generation or logging.

Notes

• HTTP/1.1 already had its own authority/Host consistency path in HttpConnection/HttpChannelState; the gap was in the HTTP/2 and HTTP/3 server entry flow where the shared compliance check was invoked before that comparison happened.
• The mismatch check only rejects when both values are present and differ after normalizing case and default ports, so requests with only one of :authority or Host present are not part of this issue.

Remediation

Upgrade org.eclipse.jetty:jetty-server to version 9.4.61, 10.0.29, 11.0.29, 12.0.35, 12.1.9 or higher.

Overview

org.eclipse.jetty:jetty-http is an is a http module for jetty server.

Affected versions of this package are vulnerable to Improper Validation of Syntactic Correctness of Input via the HttpURI class due to insufficient validation on the authority segment of a URI. An attacker can manipulate the URI parsing to redirect requests or initiate server-side requests to unintended destinations by supplying malformed URIs that bypass validation checks.

Notes:

1. This is only exploitable if the application uses decoded user data as encoded URIs in conjunction with the HttpURI class used directly;

2. The Jetty usage of the HttpURI class is not vulnerable.

Workaround

This vulnerability can be mitigated by not passing decoded user data as encoded URIs to any URI class/method, including HttpURI.

Remediation

Overview

org.eclipse.jetty:jetty-server is a lightweight highly scalable java based web server and servlet engine.

Affected versions of this package are vulnerable to Interpretation Conflict due to inconsistent handling of invalid or unusual URIs in the parse() function on HttpURI.java‎. An attacker can bypass security controls or access restricted resources by crafting specially formatted URIs that are interpreted differently by various system components.

Remediation

Upgrade org.eclipse.jetty:jetty-server to version 12.0.31, 12.1.5 or higher.
