CVE-2009-1297

iscsi_discovery in open-iscsi in SUSE openSUSE 10.3 through 11.1 and SUSE Linux Enterprise (SLE) 10 SP2 and 11, and other operating systems, allows local users to overwrite arbitrary files via a symlink attack on an unspecified temporary file that has a predictable name.

Weakness

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Affected Software

Potential Mitigations

• Follow the principle of least privilege when assigning access rights to entities in a software system.
• Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
