[9.8] [CVE-2019-17571] [tika-app] [1.23]

Description :
Severity : Sonatype CVSS 3: 9.8CVE CVSS 2.0: 0.0

Weakness : Sonatype CWE: 502

Source : National Vulnerability Database

Categories : Data

Description from CVE : Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data. This affects Log4j versions up to 1.2 up to 1.2.17.

Explanation : The log4j:log4j package is vulnerable to Remote Code Execution [RCE] due to Deserialization of Untrusted Data. The configureHierarchy and genericHierarchy methods in SocketServer.class do not verify if the file at a given file path contains any untrusted objects prior to deserializing them. A remote attacker can exploit this vulnerability by providing a path to crafted files, which result in arbitrary code execution when deserialized.
NOTE: Starting with version[s] 2.x, log4j:log4j was relocated to org.apache.logging.log4j:log4j-core. A variation of this vulnerability exists in org.apache.logging.log4j:log4j-core as CVE-2017-5645, in versions up to but excluding 2.8.2.

Detection : The application is vulnerable by using this component.

Recommendation : Starting with version[s] 2.x, log4j:log4j was relocated to org.apache.logging.log4j:log4j-core. A variation of this vulnerability exists in org.apache.logging.log4j:log4j-core as CVE-2017-5645, in versions up to but excluding 2.8.2. Therefore,it is recommended to upgrade to org.apache.logging.log4j:log4j-core version[s] 2.8.2 and above. For log4j:log4j 1.x versions however, a fix does not exist.
