Potential File Overwrite Vulnerability in Apache Tika by The Apache Software Foundation

CVE-2018-11762

What is CVE-2018-11762?

Apache Tika versions 0.9 to 1.18 are susceptible to a vulnerability that can be exploited when the user fails to specify an extract directory on the command line. If the input file includes an embedded file with an absolute path (e.g., "C:/evil.bat"), the tika-app utility may overwrite the targeted file, leading to unintended consequences. This behavior poses a significant risk, particularly for users who may inadvertently allow attackers to replace critical files on their systems.
