Detailsinfo

A vulnerability classified as problematic has been found in Smb4K 0.4/0.5/0.6/0.7. Affected is the function writefile of the component sudo. The manipulation with an unknown input leads to a symlink vulnerability. CWE is classifying the issue as CWE-61. The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Multiple race conditions in Smb4K before 0.8.0 allow local users to (1) modify arbitrary files via unspecified manipulations of Smb4K s lock file, which is not properly handled by the remove_lock_file function in core/smb4kfileio.cpp, and (2) add lines to the sudoers file via a symlink attack on temporary files, which isn t properly handled by the writeFile function in core/smb4kfileio.cpp.

The bug was discovered 12/21/2006. The weakness was disclosed 02/03/2007 by Kees Cook (Website). The advisory is shared for download at lists.berlios.de. This vulnerability is traded as CVE-2007-0472 since 01/24/2007. The exploitability is told to be difficult. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 44 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 24655 (Mandrake Linux Security Advisory : smb4k (MDKSA-2007:042)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks and running in the context l.

Upgrading to version 0.8.0 eliminates this vulnerability. A possible mitigation has been published 2 weeks after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (24655), SecurityFocus (BID 22299†), OSVDB (32981†), Secunia (SA23937†) and Vulnerability Center (SBV-14480†). The entries VDB-34815, VDB-34814 and VDB-34813 are pretty similar. Once again VulDB remains the best source for vulnerability data.
