CVE-2020-26217 is a remote code execution (RCE) vulnerability in the XStream library, which is a popular XML serialization library for Java. The vulnerability is present in versions of XStream prior to 1.4.13.
The vulnerability is caused by a deserialization issue in the XStream library, which allows an attacker to execute arbitrary code on the server. The vulnerability is exploitable when the XStream library is used to deserialize user-supplied data, such as XML or JSON.
To exploit the vulnerability, an attacker would need to craft a malicious XML or JSON payload that, when deserialized by the XStream library, would execute arbitrary code on the server. This could potentially allow an attacker to gain access to sensitive data or take control of the server.
The vulnerability was discovered by a security researcher and reported to the XStream project maintainers. The maintainers quickly released a patch to fix the vulnerability, and users are advised to upgrade to the latest version of XStream (1.4.13 or later) to protect against this vulnerability.
In terms of the provided code, there is a Metasploit module available for exploiting this vulnerability. The module is designed to exploit the deserialization issue in the XStream library and execute arbitrary code on the server. The
