Description:
Teemu Salmela has discovered a vulnerability in ELinks, which can be exploited by malicious people to expose sensitive information and manipulate data.
The vulnerability is caused due to an error in the validation of "smb://" URLs when ELinks runs smbclient commands. This can be exploited to download and overwrite local files or upload local files to a SMB share by injecting smbclient commands in the "smb://" URL.
Successful exploitation allows exposure of sensitive information or manipulation of data, but requires that the user visits a malicious "smb://" URL or gets redirected to such an URL by a malicious URL, and that the user has the smbclient program installed.
The vulnerability is confirmed in version 0.11.1. Other versions may also be affected.
Solution:
Update to version 0.11.2.
Provided and/or discovered by:
Teemu Salmela
Changelog:
2006-11-20: Added CVE reference, updated "Solution" section.
