lib/prefs.tcl in Cecilia 2.0.5 allows local users to overwrite arbitrary files via a symlink attack on the csvers temporary file.

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

Name Vendor Start Version End Version
Cecilia Cecilia 2.0.5 (including) 2.0.5 (including)
Cecilia Ubuntu dapper *
Cecilia Ubuntu feisty *
Cecilia Ubuntu gutsy *
Cecilia Ubuntu hardy *
Cecilia Ubuntu upstream *

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.
