CVE-2023-39913 : Security Advisory and Response
Untrusted code execution risk in Apache UIMA Java SDK core components. Upgrade to version 3.5.0 to prevent unverified deserialization of Java objects.
This CVE-2023-39913 affects Apache UIMA Java SDK Core, CPE, Vinci adapter, and tools, potentially leading to untrusted code execution when deserializing certain binary CAS formats.
Understanding CVE-2023-39913
Apache UIMA Java SDK versions before 3.5.0 are vulnerable to a Deserialization of Untrusted Data and Improper Input Validation issue, affecting multiple components of the SDK.
What is CVE-2023-39913?
The vulnerability stems from deserializing Java objects without proper validation, leaving the system open to arbitrary code execution.
The Impact of CVE-2023-39913
This vulnerability can allow attackers to execute remote code by exploiting the deserialization of certain binary CAS formats.
Technical Details of CVE-2023-39913
The issue affects various components of the Apache UIMA Java SDK before version 3.5.0 due to improper handling of serialized Java objects during deserialization.
Vulnerability Description
Multiple parts of the code base deserialize Java objects without verifying the data, making it susceptible to untrusted code execution.
Affected Systems and Versions
Apache UIMA Java SDK versions prior to 3.5.0 are impacted by this vulnerability.
Exploitation Mechanism
Attackers can exploit this vulnerability by leveraging the deserialization of certain binary CAS formats, allowing them to execute arbitrary code remotely.
Mitigation and Prevention
It is crucial to take immediate steps to address this vulnerability and prevent potential exploitation.
Immediate Steps to Take
Users are strongly advised to upgrade to Apache UIMA Java SDK version 3.5.0 to mitigate the issue and enhance security.
Long-Term Security Practices
To enhance security in the long term, users should ensure that serialized Java objects are validated before deserialization to prevent untrusted code execution.
Patching and Updates
For Java 9+ platforms, configuring a specific filter pattern using the "jdk.serialFilter" system property can help prevent potential exploits. Additionally, upgrading to the latest Java version is recommended for platforms running Java 1.8.
