CVE-2016-1000027 - Pivotal Spring Framework Vulnerability

Severity: Medium2020-11-05


Pivotal Spring Framework 4.1.4 suffers from a potential remote code execution (RCE) issue if used for Java deserialization of untrusted data. Depending on how the library is implemented within a product, this issue may or not occur, and authentication may be required.

The org.springframework:spring-web package is vulnerable to deserialization of untrusted data leading to Remote Code Execution (RCE). The readRemoteInvocation method in HttpInvokerServiceExporter.class does not properly verify or restrict untrusted objects prior to deserializing them. An attacker can exploit this vulnerability by sending malicious requests containing crafted objects, which when deserialized, execute arbitrary code on the vulnerable system.

The Oxygen Feedback product incorporates the Spring Framework as a third-party library. This advisory was opened to address the potential impact of this third-party library vulnerability.
