Suggestion Details:


(1) Vendor & Product Description

Vendor: 
OptimalSite

Product & Version: 
OptimalSite Content Management System (CMS) 
V.1 
V2.4

Product Description Overview: 
"Content management system OptimalSite is an online software package that enables the management of information published on a website. OptimalSite consists of the system core and integrated modules, which allow expanding website possibilities and functionality. You may select a set of modules that suits your needs best. 

Website page structure
Website page structure is presented in a tree structure similar to Windows Explorer, so that several page levels can be created for each item on the menu.  The website's structure itself can be easily edited: you can create new website pages, delete unnecessary ones, and temporarily disable individual pages.

Website languages
OptimalSite may be used to create a website in different languages, the number of which is not limited. Different information may be presented in each separate language and the structure of pages in each language may also differ. 

WYSIWYG (What You See Is What You Get) text editor
Using this universal text editor makes posting and replacing information on the website effortless.   Even a minimum knowledge of MS Word and MS Excel will make it easy to use the tools of WYSIWYG text editor and implement your ideas. 

Search function in the system
By using search function system’s administrator is able to find any information that is published in administrative environment. It is possible to execute a search in the whole system and in separate its’ modules as well.

Recycle bin function
System administrator is able to delete useless data.  All deleted data is stored in recycle bin, so administrator can restore information anytime. "






(2) Vulnerability Details:
OptimalSite web application has a computer security bug problem. It can be exploited by stored XSS attacks. This may allow a remote attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.

Several other the similar product 0-day vulnerabilities have been found by some other bug hunter researchers before. OptinalSite has patched some of them. "Openwall software releases and other related files are also available from the Openwall file archive and its mirrors. You are encouraged to use the mirrors, but be sure to verify the signatures on software you download. The more experienced users and software developers may use our CVSweb server to browse through the source code for most pieces of Openwall software along with revision history information for each source file. We publish articles, make presentations, and offer professional services." Openwall has published suggestions, advisories, solutions details related to XSS vulnerabilities.

ESPN Are Suffering Serious XSS and Dest Redirect Privilege Escalation Security Vulnerabilities










ESPN Are Suffering Serious XSS and Dest Redirect Privilege Escalation Security Vulnerabilities

Popular ESPN website (espn.go.com) has been found to be vulnerable to multiple serious XSS and Dest Redirect Privilege Escalation security vulnerabilities according to Wang Jing, a mathematics student from the School of Physical and Mathematical Sciences at Nanyang Technological University in Singapore.

Wang found a large number of ESPN’s credible links were vulnerable to XSS and Dest Redirect Privilege Escalation attacks. These vulnerabilities occur at ESPN’s “login” & “register” pages.

ESPN is one of the most common U.S.-based cable and satellite TV channel with close to 100 million subscribers. Its Alexa global rank is 63 and US rank is 14. Based on eBizMBA, “As of December 1, 2014, ESPN has an estimated 80,000,000 unique monthly visitors.” At the same time, ESPN broadcasts in more than 200 countries.

Wang posted his findings on the Full Disclosure forum. He wrote that he had reported the issues to ESPN in early May 2014 but the vulnerabilities are still unpatched. According to Wang, “Those vulnerabilities are very dangerous. Since they happen at ESPN’s “login” & “register” pages that are credible. Attackers can abuse those links to mislead ESPN’s users. The success rate of attacks may be high.“


Proof of concept videos have also been released on YouTube to illustrate an attack.
(2)Dest Redirect Privilege Escalation DEMO 

According to OWASP, “XSS allows attackers to execute scripts in the victims browser which can hijack user sessions, deface websites or redirect the user to malicious sites.” While Dest Redirect Privilege Escalation “is used in phishing attacks to get users to visit malicious sites without realizing it.”
If ESPN’s users were exploited, attackers can get their identity. Those attacks can also be used to steal password, perform denial of service attacks, spy users’ habits, alter browser functionality, access sensitive information and so on.

Wang wrote his tests were using Firefox (33.0) in Ubuntu (14.04) and IE (8.0. 7601) in Windows 8. And the attack could work without a user being logged in.

Maxwell’s Formulation – Differential Forms on Euclidean Space

Maxwell’s Formulation – Differential Forms on Euclidean Space
Author: Jing Wang
Institute: School of Physical and Mathematical Sciences, Nanyang Technological University, Singapore

One of the greatest advances in theoretical physics of the nineteenth century was Maxwell’s formulation of the the equations of electromagnetism. This article uses differential forms to solve a problem related to Maxwell’s formulation. The notion of differential form encompasses such ideas as elements of surface area and volume elements, the work exerted by a force, the flow of a fluid, and the curvature of a surface, space or hyperspace. An important operation on differential forms is exterior differentiation, which generalizes the operators div, grad, curl of vector calculus. the study of differential forms, which was initiated by E.Cartan in the years around 1900, is often termed the exterior differential calculus.However, Maxwell’s equations have many very important implications in the life of a modern person, so much so that people use devices that function off the principles in Maxwell’s equations every day without even knowing it.

Delaunay Triangulation - From 2-D Delaunay to 3-D Delaunay

Delaunay Triangulation - From 2-D Delaunay to 3-D Delaunay
Author: Jing Wang
Institute: School of Physical and Mathematical Sciences, Nanyang Technological University, Singapore





























Delaunay triangulation are widely used in scientific computing in many diverse applications. While there are numerous algorithms for computing triangulations, it is the favorable geometric properties of the Delaunay triangulation that make it so useful.


The fundamental property is the Delaunay criterion. In the case of 2-D triangulations, this is often called the empty circumcircle criterion. For a set of points in 2-D, a Delaunay triangulation of these points ensures the circumcircle associated with each triangle contains no other point in its interior. This property is important. In the illustration below, the circumcircle associated with T1 is empty. It does not contain a point in its interior. The circumcircle associated with T2 is empty. It does not contain a point in its interior. This triangulation is a Delaunay triangulation. This presentation discusses how to extend 2-D Delaunay to 3-D Delaynay.

水 - 生命、纯洁、宁静 - 美文诗歌
















水~~它意味着生命、纯洁、宁静……

水是最普通的东西。
风霜雨雪,都是水,不同状态的水。在我们的生活中它处处皆是,我们是如此的忽视它,竟忘记了它是如此的重要……

水是生命之源。
人自呱呱坠地,直至生命的终结,没有一刻可以离开它。当你远离水的时候,就像在沙漠之中,就会对它产生渴望与幻想。
地球上有75%被水所覆盖,要在浩瀚的宇宙中找寻一个地球的扩展空间,其中的一个决定因素就是那个星球上有没有液态水!

水是污浊的荡涤。
人们起床的第一项工作往往就是清洁一下自己,刷牙、洗脸,让我们每天以清新爽朗面对生活,这是水的功劳!
墨池,王羲之练字,久而久之,一池清水竟呈墨色。一池清水奉贤了自己的洁净,成就了一位况绝古今的大书法家。

山水近高天,水也为蒙尘的心洗礼!
青山绿水,高山流水,小桥流水,清江泛舟,只有在这种远离尘嚣的清新、宁静之中,人们才会忘记尘俗的勾心斗角,揭去负累的面具,素面朝天,才有了心灵的升华。

溶霜化雪渗入泥,
清净怀远呈智霖。
花红柳绿源头是,
荡尽尘嚣有冰心。

蜀繡 – 李宇春 – 唯美中文音樂風 – 好聽的音樂




















非常喜歡唯美的歌詞。“蜀繡” 曲調旋律悠揚清爽,歌者的聲音也溫暖悠揚,有著濃郁的中國情。大氣又感人至深。開始的­呢噥輕吟淺唱到慢慢綻放,如壹朵花壹洋的慢慢開放。總之,好聽。因為以前經常聽,特制作這個視頻來回憶­大學生活,逝去的青春 。


歌曲 & 歌詞
演唱:李宇春
作詞: 郭敬明
芙蓉城三月雨紛紛 四月繡花針
羽毛扇遙指千軍陣 錦緞裁幾寸
看鐵馬踏冰河 絲線縫韶華 紅塵千帳燈
山水壹程風雪再壹程
紅燭枕五月花葉深 六月杏花村
紅酥手青絲萬千根 姻緣多壹分
等殘陽照孤影 牡丹染銅樽 滿城牧笛聲
伊人倚門望君踏歸程
君可見刺繡每壹針 有人為妳疼
君可見牡丹開壹生 有人為妳等
江河入海奔 萬物為誰春
明月照不盡離別人
君可見刺繡又壹針 有人為妳疼
君可見夏雨秋風 有人為妳等
翠竹泣墨痕 錦書畫不成
情針意線繡不盡 鴛鴦枕
此生笑傲風月瘦如刀 催人老
來世與君暮暮又朝朝 多逍遙
芙蓉城三月雨紛紛 四月繡花針
羽毛扇遙指千軍陣 錦緞裁幾寸
看鐵馬踏冰河 絲線縫韶華 紅塵千帳燈
山水壹程風雪再壹程
紅燭枕五月花葉深 六月杏花村
紅酥手青絲萬千根 姻緣多壹分
等殘陽照孤影 牡丹染銅樽 滿城牧笛聲
伊人倚門望君踏歸程
君可見刺繡每壹針 有人為妳疼
君可見牡丹開壹生 有人為妳等
江河入海奔 萬物為誰春
明月照不盡離別人

情針意線繡不盡 鴛鴦枕
繞指柔破錦千萬針 杜鵑啼血聲
芙蓉花蜀國盡繽紛 轉眼塵歸塵
戰歌送離人 行人欲斷魂
濃情蜜意此話當真
君可見刺繡每壹針 有人為妳疼
君可見牡丹開壹生 有人為妳等
江河入海奔 萬物為誰春
明月照不盡離別人
君可見刺繡又壹針 有人為妳疼
君可見夏雨秋風有人 為妳等
翠竹泣墨痕 錦書畫不成
情針意線繡不盡 鴛鴦枕
翠竹泣墨痕 錦書畫不成
情針意線繡不盡 鴛鴦枕
