|
Remote Code Execution in Apache Unomi.
|
|
|
|
|
Apache Unomi allows conditions to use OGNL and MVEL scripting which
|
|
|
|
|
offers the possibility to call static Java classes from the JDK
|
|
|
|
|
that could execute code with the permission level of the running Java process.
|
|
|
|
|
This vulnerability affects all versions of Apache Unomi prior to 1.5.2. Apache Unomi users should upgrade to 1.5.2 or later.
