(more…)WebLogic Remote Code Execution Vulnerabilities (CVE-2020-2883 and CVE-2020-2884) Protection Solution
May 19, 2020
Overview
Oracle released Critical Patch Update (CPU) for April 2020 that fixes multiple vulnerabilities of different risk levels, including two critical ones (CVE-2020-2883 and CVE-2020-2884) with a CVSS score of 9.8 that allow unauthenticated attackers with network access via T3 to compromise vulnerable Oracle WebLogic Server. Successful exploitation could result in takeover of Oracle WebLogic Server, hence remote code execution.
The two vulnerabilities that exist in the Core component of WebLogic Server could be exploited without authentication or additional interaction. Since the T3 protocol is enabled by default on the WebLogic console, the two vulnerabilities can cause an extensive impact. Affected users are strongly advised to apply protection measures as soon as possible for risk aversion.

(more…)Firmware Analysis: Extraction of ASP Files in the GoAhead Architecture
May 15, 2020
GoAhead is an open-source web architecture that is widely used in embedded systems thanks to its high performance and high availability. Traditional servers built on the GoAhead architecture usually see a large number of dynamic pages written in the Active Server Pages (ASP) scripting language and functions written in C/C++ that are registered to the scripting layer for ASP scripts’ invocation. For the purpose of more thorough security audits, we should not only understand how these functions are implemented but also analyze how ASP scripts are handled. This article uses the firmware of a certain switch as an example to illustrate how to extract ASP files when GoAhead is involved.
