  2. *NetCat CMS Multiple HTTP Response Splitting (CRLF) Security Vulnerabilities* Exploit Title: NetCat CMS Multiple CRLF Security Vulnerabilities Product: NetCat CMS (Content Management System) Vendor: NetCat Vulnerable Versions: 5.01 3.12 3.0 2.4 2.3 2.2 2.1 2.0 1.1 Tested Version: 3.12 Advisory Publication: Mar 07, 2015 Latest Update: Mar 07, 2015 Vulnerability Type: Improper Neutralization of CRLF Sequences ('CRLF Injection') [CWE-93] CVE Reference: * Credit: Wang Jing [Mathematics, Nanyang Technological University (NTU), Singapore] *Advisory Details:* *(1) Vendor & Product Description:* *Vendor:* NetCat *Product & Version:* NetCat 5.01 3.12 3.0 2.4 2.3 2.2 2.1 2.0 1.1 *Vendor URL & Download:* NetCat can be got from here, http://netcat.ru/ *Product Introduction:* NetCat.ru is russian local company. "NetCat designed to create an absolute majority of the types of sites: from simple "business card" with a minimum content to complex web-based systems, from corporate offices to online stores, libraries or media data - in other words, projects completely different directions and at any level of complexity. View examples of sites running on NetCat CMS can be in a special section." "Manage the site on the basis of NetCat can even inexperienced user, because it does not require knowledge of Internet technologies, programming and markup languages. NetCat constantly improving, adds new features. In the process of finalizing necessarily take into account the wishes of our partners and clients, as well as trends in Internet development. More than 2,000 studios and private web developers have chosen for their projects is NetCat, and in 2013 sites, successfully working on our CMS, created more than 18,000." *(2) Vulnerability Details:* NetCat web application has a security bug problem. It can be exploited by HTTP Response Splitting (CRLF) attacks. This could allow a remote attacker to insert arbitrary HTTP headers, which are included in a response sent to the server. If an application does not properly filter such a request, it could be used to inject additional headers that manipulate cookies, authentication status, or more. *(2.1)* The first code flaw occurs at "/post.php" page with "redirect_url" parameter by adding "%0d%0a%20". *(2.2)* The second code flaw occurs at "redirect.php?" page with "url" parameter by adding "%0d%0a%20". *References:* http://securityrelated.blogspot.com/2015/03/netcat-cms-multiple-http-response.html http://tetraph.com/security/http-response-splitting-vulnerability/netcat-cms-multiple-http-response-splitting-crlf-security-vulnerabilities/ http://www.inzeed.com/kaleidoscope/computer-web-security/netcat-cms-multiple-http-response-splitting-crlf-security-vulnerabilities/ http://diebiyi.com/articles/%E5%AE%89%E5%85%A8/netcat-cms-multiple-http-response-splitting-crlf-security-vulnerabilities/ https://itswift.wordpress.com/2015/03/07/netcat-cms-multiple-http-response-splitting-crlf-security-vulnerabilities/ http://seclists.org/fulldisclosure/2015/Mar/8 http://packetstormsecurity.com/files/130584/NetCat-CMS-5.01-Open-Redirect.html -- Wang Jing, Division of Mathematical Sciences (MAS), School of Physical and Mathematical Sciences (SPMS), Nanyang Technological University (NTU), Singapore. http://www.tetraph.com/wangjing/ https://plus.google.com/u/0/+JingWang-tetraph-justqdjing/posts Source
  3. Oren Hafif reported a new kind of attack called Reflected File Download (https://www.blackhat.com/eu-14/briefings.html#reflected-file-download-a-new-web-attack-vector) in Black Hat Europe 2014 conference. More details about the attack you can found in his public presentation: https://www.blackhat.com/docs/eu-14/materials/eu-14-Hafif-Reflected-File-Download-A-New-Web-Attack-Vector.pdf. Google and Bing have already fixed the vulnerability but I've found the same vulnerability in AOL Search Website. A malicious user could send the link below to a victim that you download a malicious batch file from autocomplete.search.aol.com domain. In the link below we have search for 'iramar "||calc||' using the AOL autocomplete domain. The browser will encode the double quotes but the server will escape it (\") and return inside the json on the body response. Since the response has the header "Content-Type: application/x-suggestions+json;charset=UTF-8" the browser will automatically try to download the reflected file. Chrome didn't try to download the file but Internet Explorer and Firefox will. http://autocomplete.search.aol.com/autocomplete/get;calc.bat?q=iramar"||calc||&it=ws-landing&dict=en_us_search&count=8&output=json REQUEST GET http://autocomplete.search.aol.com/autocomplete/get;calc.bat?q=iramar%22||calc||&it=ws-landing&dict=en_us_search&count=8&output=json HTTP/1.1 Host: autocomplete.search.aol.com User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:33.0) Gecko/20100101 Firefox/33.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Cookie: ...

  4. # Exploit Title: Bsplayer HTTP Response BOF # Date: Jan 17 ,2015 # Exploit Author: Fady Mohamed Osman (@fady_osman) # Vendor Homepage: www.bsplayer.com # Software Link: http://www.bsplayer.com/bsplayer-english/download-free.html # Version: current (2.68). # Tested on: Windows 7 sp1 x86 version. # Exploit-db : http://www.exploit-db.com/author/?a=2986 # Youtube : https://www.youtube.com/user/cutehack3r Exploit: http://www.exploit-db.com/sploits/35841.tar.gz Bsplayer suffers from a buffer overflow vulnerability when processing the HTTP response when opening a URL. In order to exploit this bug I needed to load a dll with no null addresses and no safeseh ,ASLR or DEP. I noticed that one of the dlls that matches this criteria is (MSVCR71.dll) and it's loaded when I loaded an flv file over the network and that's why I'm sending a legitimate flv file first so later we can use the loaded dll. Also the space after the seh record is pretty small so what I did is that I added a small stage shell cdoe to add offset to esp so it points at the beginning of my buffer and then a jmp esp instruction to execute the actual shellcode. -- *Regards,* Fady Osman about.me/Fady_Osman <http://about.me/Fady_Osman> Source
