Detailsinfo

A vulnerability was found in Linux Kernel up to 2.3.0 (Operating System). It has been declared as problematic. Affected by this vulnerability is some unknown functionality of the file lstat.cgi. The manipulation of the argument template with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality. The summary by CVE is:

Directory traversal vulnerability in lstat.cgi in LinuxStat before 2.3.1 allows remote attackers to read arbitrary files via (1) .. (dot dot) sequences or (2) absolute paths to the template parameter.

The weakness was published 10/21/2004 by neros (Website). It is possible to read the advisory at securityfocus.com. This vulnerability is known as CVE-2004-2640 since 12/04/2005. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details and also a public exploit are known. The attack technique deployed by this issue is T1006 according to MITRE ATT&CK.

After immediately, there has been an exploit disclosed. It is possible to download the exploit at exploit-db.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k.
