Potential Risk of CVE

30th Jun, 2018 – VMware releases security updates

VMware Releases Security Updates – June 30, 2018 VMware ESXi, Workstation, and Fusion contain multiple out-of-bounds read vulnerabilities in the shader translator. A local user can trigger an out-of-bounds memory read error in the shader translator to obtain potentially sensitive information or cause their virtual machine to crash. The browser’s built-in shader translation facilities, it is a underlying platform’s graphics driver. So, VMware user must staying alert!

Public safety, Under our observation, Virus & Malware

The world cup 2018 – malicious game website and phishing email also involved in this competition. This like malware transformation of football shooting.

THE 2018 WORLD CUP lure hacker interest, a breeding ground for hackers. The phishing campaign linked to the start of the FIFA World Cup where cyber-criminals attempt to lure would-be victims into downloading. For instance, Games, email and related information. Such download contain malware and let the downloader become cyber attack victim.

How do you defend against this football (malware)? 1. Use and maintain antivirus software. 2. Keep software and operating systems up-to-date. 3. Be wary of downloading files from websites. 4. Think before you Click!

Data privacy, Under our observation

Sometimes RESTful API jeopardize your personal data privacy

Ticketmaster Hacked! The company sold 500 million tickets to 86 million people last year. It is important for you to select the best API to create chatbot. Common way call a RESTful API from your Chatbot. What makes RESTful APIs even more attractive is that the same REST API could potentially be used both by a web application, as well as other clients such as a mobile application. But RESTful API require hardening. Otherwise it is not in secure way.

Common REST API security risk (see below):

  • unencrypted payload
  • Lack of input  sanitisaton

And therefore payments or approvals process must put into a secure place which is usually not the client app.

See whether does it a defect on GNU Binutils (status update on 25th June 2018)

 

Bug (CVE-2018-7642) found GNU Binutils 2.30 on 24th Feb 2018. GNU Binary Utilities, or binutils, are a set of programming tools for creating and managing binary programs, object files, libraries, profile data, and assembly source code. The GNU compiler Collection (gcc) play a important role of software development. If a bug will be happened in compiler. We might imagine that it will effect the software development life cycle (SDLC). A bug found earlier this year on GNU Binutils hits system crash. But bug found on April 2018 looks expanded and not only system crash. Should you have interest, please refer below url for reference.

Found buffer overflow, integrate overflow & memory corruption in redis – Jun 2018

If you have a database of geo-located data, what is the appropriate database setup? The geospatial require fastest database so Redis is one of the option.Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs and geospatial indexes with radius queries. Found buffer overflow, integrate overflow & memory corruption in redis. Technical details shown as below:

Will satellites be affected by a buffer overflow vulnerability?

5 Comments

Will satellites be affected by a buffer overflow vulnerability? Heard that hacker interested of the satellite device. This news let you imagine that it is a APT attack, right? It looks that political issues run around the world. Who’s right? Who’s wrong? Perhaps god also doesn’t know. On 16th Jan 2018, the confirmation of Solaris and SPARC Spectre vulnerabilities comes as Oracle delivers its Meltdown/Spectre patches for its x86 servers. Meldown and Spectre look like a AIDS or ebola disease.

The CDMU (Command and Data Management Unit) is used for spacecraft control especially satellities. It is composed of the following functional element. The LEON-3 CPU, developed by Gaisler Research, is a 32 bit synthesisable processor core based on the SPARC V8 architecture. Oh! As far as I know, hacker can be exploiting SPARC Buffer Overflow vulnerabilities. Perhaps it is not easy to do the patch management on the sky?

“With great power comes great responsibility” (CVE-2018-6961)

Sometimes we review the vulnerability check list. We are aim to address high severity of vulnerabilities items in first piority. From technical point of view it looks correct. Since some medium vulnerabilities especially cookie or cross site scripting issue may spend more time to do the remediation. A security advisories announced by VMware on 15th May 2018 bring to my attentions. That is CVE-2018-6961 (see attached diagram). It looks that the orginal Web UI function is a dilemma! Web UI in frequent have design weakness thus let attacker do the code injection. Since there is no prefect item in the world. The attacker might relies on CVE-2018-6961 execute Use-After-Free vulnerability. As a result it affected drag-and-drop functionality and triggered through the Backdoor RPC interface.

Remark:  Staying alert of this directory (lib/include/backdoor_def.h)

Potential Risk of CVE, Under our observation

Not seen attack related to CVE-2018-7559, but require considerations and stay alert.

US Homeland security has announcement three times within this year ( April 16, 2018,May 29, 2018 and June 14, 2018) thus to urge the world staying alert malicious attack.Perhaps the industrial sector especailly oil and gas, power supplier facilities has detective and preventive control in placed. Hacker will be facing difficulties for attack. As far as we know, OPC source code on GitHub contains a flaw let remote attacker use the Server’s private key to decrypt and sign messages by using information obtained by sending invalid UserIdentityTokens encrypted with the Basic128Rsa15 security policy. The successful result could allow an attacker to decrypt passwords even if they are encrypted with another security policy such as Basic256Sha256. This flaw found on April this year and remediation has been announced. However, I believe that cyber security attacks exploit of this vulnerability will be happened soon.
