IBM SDK Java Technology Edition Sandbox javax.rmi.CORBA.ValueHandler deserialization

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability classified as very critical was found in IBM SDK Java Technology Edition up to 6.0.16.24/6.1.8.24/7.0.9.39/7.1.3.39/8.0.2.x (Programming Language Software). This vulnerability affects the function javax.rmi.CORBA.ValueHandler of the component Sandbox. The manipulation with an unknown input leads to a deserialization vulnerability. The CWE definition for the vulnerability is CWE-502. The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The com.ibm.rmi.io.SunSerializableFactory class in IBM SDK, Java Technology Edition 6 before SR16 FP25 (6.0.16.25), 6 R1 before SR8 FP25 (6.1.8.25), 7 before SR9 FP40 (7.0.9.40), 7 R1 before SR3 FP40 (7.1.3.40), and 8 before SR3 (8.0.3.0) does not properly deserialize classes in an AccessController doPrivileged block, which allows remote attackers to bypass a sandbox protection mechanism and execute arbitrary code as demonstrated by the readValue method of the com.ibm.rmi.io.ValueHandlerPool.ValueHandlerSingleton class, which implements the javax.rmi.CORBA.ValueHandler interface. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-5456.

The weakness was shared 06/03/2016 by Adam Gowdiak with Security Explorations (Website). The advisory is shared for download at securityfocus.com. This vulnerability was named CVE-2016-0376 since 12/08/2015. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 08/22/2022). It is expected to see the exploit prices for this product increasing in the near future.

The vulnerability scanner Nessus provides a plugin with the ID 90819 (RHEL 5 : java-1.7.0-ibm (RHSA-2016:0702)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Red Hat Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 121766 (IBM Java SDK Multiple Vulnerabilities (Oracle April 19 2016 CPU, IBM Security Update April 2016)).

Upgrading to version 6.0.16.25, 6.1.8.25, 7.0.9.40, 7.1.3.40 or 8.0.3.0 eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the vulnerability database at Tenable (90819). The entries 82658, 82655, 82659 and 82653 are related to this item.
