It has been a quite while since I haven’t released a new part of unexpected journey article serie. Particularly this small 0-day research project has been certainly didactic to me. Thus, I’ve decided to write down the process of achieving remote code execution on MicroFocus Secure Messaging Gateway product. Read More
It is an interesting coincidence that almost 1 year ago we identified a critical security issue in a different product (Eventlog Analyzer) of this company. Now, this time we’ve came across with another product of this company during penetration test. To be honest I’ve seen more than 20 different high/critical vulnerability during the analysis of the product but I will only share two of them now, as a full disclosure. Read More
The goal of Xplico is extract from an internet traffic capture the applications data contained. For example, from a pcap file Xplico extracts each email (POP, IMAP, and SMTP protocols), all HTTP contents, each VoIP call (SIP), FTP, TFTP, and so on. Xplico isn’t a network protocol analyzer. Xplico is an open source Network Forensic Analysis Tool (NFAT).
Because of the increasing security standards inside operating systems and rapid improvements on malware detection technologies today’s malware authors takes advantage of the transparency offered by in-memory execution methods. In-memory execution or fileless execution of a PE file can be defined as executing a compiled PE file inside the memory with manually performing the operations that OS loader supposed to do when executing the PE file normally. In-memory execution of a malware facilitates the obfuscation and anti-emulation techniques. Additionally the malware that is using such methods leaves less footprints on the system since it does not have to possess a file inside the hard drive. Combining in-memory execution methods and multi stage infection models allows malware to infect systems with very small sized loader programs; only purpose of a loader is loading and executing the actual malware code via connecting to a remote system. Using small loader codes are hard to detect by security products because of the purpose and the code fragments of loaders are very common among legitimate applications. Malware that are using this approach can still be detected with scanning the memory and inspecting the behaviors of processes but in terms of security products these operation are harder to implement and costly because of the higher resource usage (Ramilli, 2010).

Framework’s security has been a known topic for security folks. In fact, we already seen a real impact of single vulnerability within a framework on Apache Struts case. If we consider this risk from the point of products vendor, we could see very similar case. In this article, I will show you how we get RCE on different Trend Micro products because of same codebase used by across the different products. Read More
