Horizon Alert
Summary of the vulnerability and why it matters
The JBoss Application Server component within Red Hat Enterprise Application Platform is vulnerable. The flaw allows for the execution of arbitrary code by processing specially crafted serialized data. This could lead to significant business risk, including unauthorized system access and data compromise.
- Vulnerable component: JBoss Application Server
- Core weakness: Unrestricted deserialization of data
- Main business impact: Arbitrary code execution
Attack Path
How an attacker could exploit the issue
The JBoss Application Server, when configured with the HTTP Invoker, can be exploited by an attacker to execute arbitrary code. This is achieved by sending specially crafted serialized data to the server, which bypasses security checks in the ReadOnlyAccessFilter's doFilter method. Successful exploitation allows an attacker to gain control over the affected system.
- Exposure occurs through the HTTP Invoker.
- Attacker sends crafted serialized data.
- Arbitrary code execution results.
