GEN:SID | 1:1600 |
Message | WEB-CGI htsearch arbitrary configuration file attempt |
Summary | This event is generated when an attempt is made to read a file on a host using a well known vulnerability in htdig. |
Impact | Severe. Unauthorized file access |
Detailed Information | Some versions of htdig allow inclusions to be made from configuration files as a parameter to the htsearch function. Any file can be included by enclosing it in single quotes ('foo'). Using this vulnerability, any single quoted input string (`....`) is included as an index file by htsearch. This allows an attacker to read any file on the host. This event is generated when a request is made to the cgi script htsearch with file inclusion attempted. Refer to the rule with sid 1601 for further exploitation attempts. |
Affected Systems | HTDig versions 3.1.1, 3.1.2, 3.1.3, 3.1.4 and 3.2.0b1 |
Attack Scenarios | An attacker can try to include a file in the search parameters for htdig by using the -c flag. For example: http://www.foo.com/cgi-bin/htsearch?-c%60/anyfile%60 |
Ease of Attack | Simple. No exploit scripts required |
Corrective Action | Upgrade to the latest non-affected version of the software. |
