Deserialization of Untrusted Data
A deserialization vulnerability was discovered in Apache Dubbo 2.7.0 before 2.7.5, 2.6.0 before 2.6.8, and 2.5.x versions, in the HTTP protocol. This issue exists due to the use of a remote deserialization service in Spring Framework, whose documentation explicitly recommends not to use with untrusted data, combined with an outdated dependency. This allows triggering remote code execution with no authentication.
CWE-502 - Deserialization of Untrusted Data
Deserialization of untrusted data vulnerabilities enable an attacker to replace or manipulate a serialized object, replacing it with malicious data. When the object is deserialized at the victim's end the malicious data is able to compromise the victim’s system. The exploit can be devastating, its impact may range from privilege escalation, broken access control, or denial of service attacks to allowing unauthorized access to the application's internal code and logic which can compromise the entire system.
