Exploitation evidence

Disclosed: evidence found.
CVE published 24 Sep 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

The purpose of this text-only errata is to inform you about the enhancements that improve your developer experience and ensure the security and stability of your products: * CVE-2024-45294 ca.uhn.hapi.fhir/org.hl7.fhir.utilities: XXE vulnerability in XSLT transforms in * CVE-2024-45294 ca.uhn.hapi.fhir/org.hl7.fhir.r5: XXE vulnerability in XSLT transforms in * CVE-2024-45294 ca.uhn.hapi.fhir/org.hl7.fhir.r4: XXE vulnerability in XSLT transforms in * CVE-2024-45294 ca.uhn.hapi.fhir/org.hl7.fhir.dstu3: XXE vulnerability in XSLT transforms in * CVE-2024-45294 ca.uhn.hapi.fhir/org.hl7.fhir.dstu2016may: XXE vulnerability in XSLT transforms in * CVE-2024-8391 io.vertx/vertx-grpc-server: Vertx gRPC server does not limit the maximum message size * CVE-2024-8391 io.vertx/vertx-grpc-client: Vertx gRPC server does not limit the maximum message size * CVE-2024-32007 org.apache.cxf/cxf-rt-rs-security-jose: apache: cxf: org.apache.cxf:cxf-rt-rs-security-jose: Denial of Service vulnerability in JOSE * CVE-2024-41172 org.apache.cxf/cxf-rt-transports-http: unrestricted memory consumption in CXF HTTP clients * CVE-2024-35255 com.azure/azure-identity: Azure Identity Libraries Elevation of Privilege Vulnerability in github.com/Azure/azure-sdk-for-go/sdk/azidentity

Impact

The XXE vulnerability (CVE-2024-45294) can lead to unauthorized disclosure of sensitive data from the host system by processing malicious XML input. The Vert.x gRPC message size issue (CVE-2024-8391) can cause resource exhaustion, potentially leading to denial of service. The Apache CXF vulnerabilities may allow denial of service via resource consumption or memory exhaustion. The Azure Identity Libraries vulnerability could allow elevation of privilege. Collectively, these vulnerabilities pose risks to confidentiality, availability, and privilege integrity of affected systems if exploited.

Summary

This advisory covers multiple vulnerabilities fixed in Red Hat Build of Apache Camel 4.4 for Quarkus 3.8 (RHBQ 3.8.6.GA). CVE-2024-45294 is an XXE vulnerability in XSLT transforms within several HL7 FHIR components, allowing attackers to exploit XML external entity injection to read arbitrary files or cause denial of service. CVE-2024-8391 involves Vert.x gRPC server and client components that do not limit maximum message size, potentially leading to resource exhaustion. Other fixed issues include denial of service in Apache CXF JOSE security components (CVE-2024-32007), unrestricted memory consumption in CXF HTTP clients (CVE-2024-41172), and an elevation of privilege vulnerability in Azure Identity Libraries (CVE-2024-35255). The Red Hat advisory provides an official update (RHBQ 3.8.6.GA) to address these issues, improving security and stability.

CWE-770Allocation of Resources Without Limits or Throttling (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #25
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
Requirements
Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
Architecture and Design
Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended.

CWE-362Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') (opens in a new tab)
Class weaknessLikelihood of exploit: MediumOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
Architecture and Design
In languages that support it, use synchronization primitives. Only wrap these around critical code to minimize the impact on performance.
Architecture and Design
Use thread-safe capabilities such as the data access abstraction in Spring.
Architecture and Design
Minimize the usage of shared resources in order to remove as much complexity as possible from the control flow and to reduce the likelihood of unexpected conditions occurring.

CWE-401Missing Release of Memory after Effective Lifetime (opens in a new tab)
Variant weaknessLikelihood of exploit: Medium
The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.
Implementation · Libraries or Frameworks
Choose a language or tool that provides automatic memory management, or makes manual memory management less error-prone.
Architecture and Design
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Architecture and Design · Build and Compilation
Consider using the Boehm-Demers-Weiser garbage collector (bdwgc), which can help avoid leaks.

Base weaknessOWASP Top 10 A02:2025: Security Misconfiguration (opens in a new tab)
The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.
Implementation · System Configuration
Many XML parsers and validators can be configured to disable external entity expansion.
