Name of the Vulnerable Software and Affected Versions Divisa Proxia Suite versions prior to 9.12.16 Divisa Proxia Suite version 9.11.19 Divisa Proxia Suite version 9.10.26 Divisa Proxia Suite version 9.9.8 Divisa Proxia Suite version 9.8.43 Divisa Proxia Suite version 9.7.10 Divisa Proxia Suite versions 10.0 prior to 10.0.32 Divisa Proxia Suite versions 10.1 prior to 10.1.5 SparkSpace versions 1.0 prior to 1.0.30 SparkSpace versions 1.1 prior to 1.1.2 SparkSpace versions 1.2 prior to 1.2.4 Proxia PHR versions 1.0 prior to 1.0.30 Proxia PHR versions 1.1 prior to 1.1.2

Description The issue allows remote code execution via untrusted Java deserialization. The proxia-error cookie is insecurely deserialized in every request, enabling an unauthenticated attacker to craft a serialized payload and execute arbitrary code via the prepareError function in the com.divisait.dv2ee.controller.MVCControllerServlet class of the dv2eemvc.jar component.
