TITLE

TP-Link EAP Controller lacks RMI authentication and is vulnerable to deserialization attacks

DESCRIPTION

The AdminUI in HPE Operations Manager (OM) before 9.21.130 on Linux, Unix, and Solaris allows remote attackers to execute arbitrary commands via a crafted serialized Java object, related to the Apache Commons Collections (ACC) library. The TP-LINK EAP Controller is TP-LINK's software for remotely controlling wireless access point devices. EAP Controller for Linux lacks user authentication for RMI service commands, as well as utilizes an outdated vulnerable version of Apache commons-collections, which may allow an attacker to implement deserialization attacks and control the EAP Controller server. Supplementary information : CWE Vulnerability type by CWE-284: Improper Access Control ( Inappropriate access control ) Has been identified. http://cwe.mitre.org/data/definitions/284.htmlSkillfully crafted serialized by a third party Java An arbitrary command may be executed through the object.

Here you can find advice on countermeasures and links to related information. In addition, entries related to this vulnerability (COLLECTIONS-580) Is built on a bug management system. Official view https://blogs.apache.org/foundation/entry/apache_commons_statement_to_widespread Entries related to this vulnerability (COLLECTIONS-580) https://issues.apache.org/jira/browse/COLLECTIONS-580 ACC other than, Groovy And Spring The same problem is being investigated for these issues. Lawrence Mr. and Frohoff In his presentation material, Java not only Python And Ruby It is stated that the same problem exists in applications and libraries written in the above. Regardless of the programming language or library used, it is important to fully consider the data serialization capabilities from the software design stage.Apache Commons Collections I'm using a library Java Application or Java Library is optional Java It may be possible to execute code. Also, ACC Even if the library is not used directly, it can be accessed by specifying the class path. ACC If the library exists, any Java It may be possible to execute code. It can extend or add Java collections framework. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Cisco Security Advisory: Vulnerability in Java Deserialization Affecting Cisco Products Advisory ID: cisco-sa-20151209-java-deserialization Revision 1.0 For Public Release: 2015 December 9 16:00 GMT +--------------------------------------------------------------------- Summary ======= A vulnerability in the Java deserialization used by the Apache Commons Collections (ACC) library could allow an unauthenticated, remote attacker to execute arbitrary code. The vulnerability is due to insecure deserialization of user-supplied content by the affected software. The report contains detailed proof-of-concept code for a number of applications, including WebSphere Application Server, JBoss, Jenkins, OpenNMS, and WebLogic. A wide range of potential impacts includes allowing the attacker to obtain sensitive information. Object serialization is a technique that many programming languages use to convert an object into a sequence of bits for transfer purposes. Deserialization is a technique that reassembles those bits back to an object. Many applications accept serialized objects from the network without performing input validation checks before deserializing it.
