TIBCO would like to extend its appreciation to Andres Tarasce Acura of the SIA Group for discovery of this vulnerability, which has been addressed in the 7.5.1 release.
TIBCO Rendezvous daemon components listed below contain a buffer overflow vulnerability in the HTTP administrative interface. The impact of this vulnerability may include remote execution of arbitrary code, information disclosure, and denial of service.
TIBCO has released updates which address critical vulnerabilities in daemon components of TIBCO Rendezvous and TIBCO Runtime Agent. TIBCO strongly recommends sites running the affected components to install the update or take mitigating action as appropriate.
TIBCO Rendezvous versions below 7.5.1
TIBCO Runtime Agent (TRA) versions below 5.4
TIBCO Hawk versions below 4.6.1
The following components are affected:
The impact of this vulnerability varies depending on the operating system, configuration options of the daemon, and the privilege levels of the user that invokes the daemon.
On Unix based systems, the successful exploit will allow arbitrary code execution with the privileges of the user that invoked that daemon, with the exception of user id 0 ("root"). If the daemon component was invoked by user id 0, a successful exploit will result in access to privileges of user id 65534 ("nobody").
On Windows based systems, the successful exploit will allow arbitrary code execution with the privileges of the user that invoked that daemon. If the daemon component is installed as a system service, this will result in access to system privileges.
Upgrade TIBCO Rendezvous to version 7.5.1 or above. This is strongly recommended.
If an upgrade is not possible, the following actions can mitigate the vulnerability:
