CWE-306: Missing Authentication for Critical Function - CVE-2018-5393

EAP Controller for Linux utilizes a Java remote method invocation (RMI) service for remote control. The RMI interface does not require any authentication before use. Remote attackers can implement deserialization attacks through the RMI protocol. Successful attacks may allow a remote attacker to remotely control the target server and execute Java functions or bytecode.

CWE-502: Deserialization of Untrusted Data - CVE-2015-6420

EAP Controller for Linux bundles a vulnerable version of Apache commons-collections v3.2.1 with the software, which appears to be the root cause of the vulnerability. Therefore, EAP Controller v2.5.3 and earlier are vulnerable to CVE-2015-6420 as documented in VU#576313.

EAP Controller v2.5.3 and earlier for Linux are affected by both vulnerabilities.

A Java application or library with the Apache Commons Collections library in its classpath may be coerced into executing arbitrary Java functions or bytecode.

The Omada Controller software v3.0.2 and later are not affected by this issue. Software download is available on the TP-Link support website. If older software must be used, users can help mitigate and reduce risk by updating the vulnerable libraries does not necessarily eliminate the vulnerability in all scenarios, as described in As described in VU#576313.

Update Apache commons-collections

Affected users should update the system Apache commons-collections library to at least version 3.2.2 or 4.1. For details, please see VU#576313.

Update the JRE version of EAP

Affected users should also update the Java Runtime Environment (JRE) used by EAP to the latest available version. Recent versions of JRE have improved deserialization protection features.
