CVE-2021-29505 Scanner Detail

XStream is a popular Java library used for serializing and deserializing objects. It transforms Java objects into XML and back again, allowing for easy storage and transmission of complex data structures. Widely used across various Java applications and platforms, XStream simplifies data manipulation and persistence, making it a critical component in many software development projects. Its flexibility and ease of use have made it a standard choice for developers needing to process XML content or manage application settings and data exchange.

The vulnerability stems from XStream's handling of XML content, where certain XML structures can trigger the deserialization of objects in a manner that executes Java code. This particular flaw exploits the library's extended capabilities to interpret XML data, leading to an uncontrolled execution environment. Attackers can leverage this by sending crafted XML payloads that exploit the deserialization process, allowing them to run malicious code remotely on the victim's machine.

Exploiting this vulnerability could have drastic effects on the confidentiality, integrity, and availability of the systems running vulnerable versions of XStream. Attackers could gain unauthorized access, extract sensitive information, manipulate or delete data, install malware, and even leverage the compromised system to launch further attacks. The impact of this vulnerability underscores the importance of secure coding practices and keeping third-party libraries up to date.
