CVE-2024-43383: Critical Flaw in Apache Lucene.NET Exposes Users to Remote Code Execution
Developers using Apache Lucene.NET are urged to update their systems immediately following the discovery of a serious security flaw that could allow attackers to remotely execute malicious code.
The vulnerability, identified as CVE-2024-43383, affects the Replicator library in Lucene.NET versions 4.8.0-beta00005 through 4.8.0-beta00016. This flaw stems from the library’s improper handling of untrusted data during deserialization.
Attackers who can intercept traffic between a replication client and server, or manipulate the target replication node URL, can exploit this vulnerability. By injecting a specially crafted JSON response, they can trigger the deserialization of malicious code, potentially granting them full control over the affected system.
Successful exploitation of this vulnerability could have severe consequences, including:
- Remote Code Execution: Attackers could execute arbitrary code on the vulnerable system.
- Data Breaches: Sensitive information could be accessed and stolen.
- System Takeover: Attackers could gain complete control of the affected system.
The Apache Lucene.NET team has addressed this vulnerability in version 4.8.0-beta00017. All users of affected versions are strongly advised to upgrade to this latest release immediately.
Apache Lucene.NET is a widely used open-source search library, powering numerous applications and services. Developers should prioritize secure coding practices and implement robust input validation to prevent similar vulnerabilities in the future.
