CVE-2008-5746

Sun SNMP Management Agent (SUNWmasf) 1.4u2 through 1.5.4 allows local users to overwrite arbitrary files and gain privileges via a symlink attack on temporary files.

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.
