[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-2423) checkEntityPermission only checks one method
checkEntityPermission only checks one method
--------------------------------------------
Key: JBSEAM-2423
URL: http://jira.jboss.com/jira/browse/JBSEAM-2423
Project: JBoss Seam
Issue Type: Bug
Components: Security
Affects Versions: 2.0.1.CR1
Environment: JPA on tomcat6
Reporter: Andrew
Priority: Critical
If an entity has more than one method marked as @PrePersist, only one method is used to
check for security. All methods should be considered and the result "anded"
together.
Code in the Identity bean only checks for a @Restrict on the first method found. In my
case, I extend an object with a @PrePersist with no @Restrict. My entity has a method:
@PrePersist @PreUpdate @PreRemove @Restrict
public void beforeChange() {}
(everything is restricted except for read access)
According to the PrePersist documentation, multiple PrePersist methods are valid. There
are workarounds, but this is dangerous code. If it were not for my unit tests it could
have slipped through. The seam documentation does not mention this limitation
I marked this as critical as it creates security holes in the application.
Here is the relevant code:
public void checkEntityPermission(Object entity, EntityAction action)
{
isLoggedIn(true);
PersistenceProvider provider = PersistenceProvider.instance();
Class beanClass = provider.getBeanClass(entity);
if (beanClass != null)
{
String name = Seam.getComponentName(entity.getClass());
if (name == null) name = beanClass.getName();
Method m = null;
switch (action)
{
case READ:
m = provider.getPostLoadMethod(beanClass);
break;
case INSERT:
m = provider.getPrePersistMethod(beanClass);
break;
case UPDATE:
m = provider.getPreUpdateMethod(beanClass);
break;
case DELETE:
m = provider.getPreRemoveMethod(beanClass);
}
Restrict restrict = null;
if (m != null && m.isAnnotationPresent(Restrict.class))
{
restrict = m.getAnnotation(Restrict.class);
}
else if (entity.getClass().isAnnotationPresent(Restrict.class))
{
restrict = entity.getClass().getAnnotation(Restrict.class);
}
if (restrict != null)
{
if (Strings.isEmpty(restrict.value()))
{
checkPermission(name, action.toString(), entity);
}
else
{
checkRestriction(restrict.value());
}
}
}
