CVE-2019-0188
Description
Apache Camel prior to 2.24.0 contains an XML external entity injection (XXE) vulnerability (CWE-611) due to using an outdated vulnerable JSON-lib library. This affects only the camel-xmljson component, which was removed.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Apache Camel prior to 2.24.0 uses an outdated JSON-lib library allowing XXE to read arbitrary files via crafted requests.
Vulnerability
CVE-2019-0188 is an XML external entity injection (XXE) vulnerability in Apache Camel before version 2.24.0, present only in the camel-xmljson component. The root cause is the use of an outdated, vulnerable JSON-lib library that fails to disable external entity processing when converting XML to JSON [1][2]. This issue is classified as CWE-611.
Exploitation
An attacker can trigger the vulnerability by sending a specially crafted XML request to an application that uses the camel-xmljson component. No authentication is required, the attack can be launched over the network, and the complexity is low [2]. The only prerequisite is that the component is enabled and processing attacker-controlled XML.
Impact
Successful exploitation allows an attacker to read arbitrary files from the server's file system, potentially exposing sensitive configuration data, secrets, or other confidential information [2]. The confidentiality impact is limited to file read; integrity and availability are not affected.
Mitigation
The vulnerable JSON-lib library and camel-xmljson component were removed in Apache Camel version 2.24.0 [1][2][4]. Users should update to 2.24.0 or later. No workaround is mentioned; the component has been fully removed from the distribution.
