Vulnerability in Oracle Business Intelligence Enterprise Edition (OBIEE) within Oracle Fusion Middleware, component "Analytics Web General", affecting supported versions 5.5.0.0.0, 11.1.1.9.0, 12.2.1.3.0, and 12.2.1.4.0. The issue is described as easily exploitable by an unauthenticated attacker with network access over HTTP, enabling compromise/takeover of the OBIEE instance (CVSS v3.0 9.8: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

This repository provides a proof-of-concept (PoC) exploit for CVE-2020-2950, a critical deserialization vulnerability in Oracle Business Intelligence (BI) products. The exploit targets the AMF (Action Message Format) endpoint at '/analytics/jbips/messagebroker/cs/' and leverages a Java deserialization chain to achieve remote code execution. The main exploit logic is implemented in 'src/main/java/AMF.java', which constructs a malicious Java object chain using classes such as LimitFilter, ChainedExtractor, and ReflectionExtractor. The payload is serialized into an AMF message and written to 'C:\Users\Public\amf.bin'. This file can then be sent to the vulnerable Oracle BI endpoint, where deserialization triggers execution of arbitrary system commands supplied via a base64-encoded HTTP header ('cmd'). The repository includes supporting files for Java project configuration and a detailed README.md explaining the vulnerability, affected versions, and exploitation process. The exploit is a PoC and requires specific target conditions (Java 8u76 or earlier, no security manager, and a vulnerable Oracle BI version).
