Detailsinfo

A vulnerability was found in IBM WebSphere MQ up to 7.5.0.3 (Application Server Software). It has been rated as critical. This issue affects an unknown functionality of the component TCP Listener inetd. The manipulation with an unknown input leads to a denial of service vulnerability. Using CWE to declare the problem leads to CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. Impacted is availability. The summary by CVE is:

inetd in IBM WebSphere MQ 7.1.x before 7.1.0.5 and 7.5.x before 7.5.0.4 allows remote attackers to cause a denial of service (disk or CPU consumption) via unspecified vectors.
The advisory summarizes:
The TCP/IP listener (inetd) can be used with WebSphere MQ on UNIX and IBM i systems.

The weakness was published 05/01/2014 as swg21670374 as confirmed advisory (Website). It is possible to read the advisory at www-01.ibm.com. The identification of this vulnerability is CVE-2014-0911 since 01/06/2014. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. The technical details are unknown and an exploit is not publicly available. The advisory points out:

A denial of service vulnerability exists and could be exploited by a remotely connected user to either create FDCs which could fill the file system, or cause the inetd process to enter an infinite loop consuming all CPU resources. This vulnerability does not affect customers using the MQ listener (runmqlsr).

Upgrading to version 7.1.0.4 or 7.5.0.3 eliminates this vulnerability. The upgrade is hosted for download at 7.5.0.3. A possible mitigation has been published immediately after the disclosure of the vulnerability. The advisory contains the following remark:

Change to using the MQ listener (runmqlsr) instead of the TCP listener (inetd).

The vulnerability is also documented in the databases at X-Force (91876), SecurityFocus (BID 67207†), SecurityTracker (ID 1030212†) and Vulnerability Center (SBV-45017†). Be aware that VulDB is the high quality source for vulnerability data.
