It is XML-based messaging thus run on top of HTTP/HTTPS.
That is the reason why firewall cannot significant block them.

Security Advisory – Six Vulnerabilities in Some Huawei Products


Attention: Stay Alert – Multiple Vulnerabilities in PHP Could Allow for Arbitrary Code Execution


PHP is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.

Security concern by security experts

The security issues are typically exposed when PHP code makes use of system-level calls.

Found critical security problem today! – Original release date: April 27, 2018

The Multi-State Information Sharing & Analysis Center (MS-ISAC) has released an advisory on multiple Hypertext Preprocessor (PHP) vulnerabilities. An attacker could exploit one of these vulnerabilities to take control of an affected system.

NCCIC encourages users and administrators to review MS-ISAC Advisory 2018-046 and the PHP Downloads page and apply the necessary updates.

See whether any short term remediation can take before upgrade?

1.Restrict PHP Information Leakage


2.Disable Remote Code Execution



3.Not show errors to the visitors

(/etc/php.d/security.ini file)



4.Disable Dangerous PHP Functions (php.ini)

disable_functions =exec,passthru,



5.Upload Files (/etc/php.d/ directory)


6.Control File System Access

always keep the open_basedir directive set to the /var/www/html directory.


7.Control the POST Size (/etc/php.d/security.ini)

CVE-2018-0229: See whether is there any attack make use of this vulnerability transform another type of attack in future?

Seems firewall administrator do not take the single sign-on authentication method in firewall. Perhaps it can’t fulfill audit requirement.  Cisco found SAML Authentication Session Fixation Vulnerability. The vulnerability exists because there is no mechanism for the ASA or FTD Software to detect that the authentication request originates from the AnyConnect client directly. An attacker could exploit this vulnerability by persuading a user to click a crafted link and authenticating using the company’s Identity Provider (IdP).  My concerns is that see whether is there any attack make use of this vulnerability transform another type of attack in future?

Cisco Official announcement is shown as below:


Be alert! Vulnerability in the Java SE, Java SE Embedded and JRockit component of Oracle Java SE (subcomponent: Serialization). 

The security concerns on CVE-2018-2815, please staying alert. For more details, please see below:

  1. The Java Security Architecture (JSA) defines ways for unprivileged code to perform privileged operations using


2. The method includes create a new PrivilegedIntrospectHelper.

3. The new PrivilegedIntrospectHelper will be executed on a privileged block. This block will all internalIntrospecthelper(bean,prop,value,request,param,ignoreMethodNF) which will allow to invoke encapsulation (setter).

4. Result:

With encapsulation we pretend that nothing is revealed about the internal representation of an object, and we interact with our components only through their public interfaces; a desirable attribute that we usually exploit later when we want to change the internal representation of data in a component without breaking any code from its users.

Hackers jailbreak MyEtherWallet Infrastructure (Apr 2018)

ISPs tend to restrict what an end customer can advertise. However, any ISP do not filter customer advertisements.
A possible factor let’s hacker compromise the customer router thus advertise errant information into the global routing table.

An attackers stolen at least $13,000 in Ethereum within two hours.

Security expert speculate that it is a DNS attack. But many attack method can be used. For example: BGP hijacking. The scenario displayed on above diagram.
