CWEhttps://cwe.mitre.org/data/definitions/59.html

gpsdrive (aka gpsdrive-scripts) 2.10~pre4 allows local users to overwrite arbitrary files via a symlink attack on the (a) /tmp/.smswatch or (b) /tmp/gpsdrivepos temporary file, related to (1) examples/gpssmswatch and (2) src/splash.c, different vectors than CVE-2008-4959 and CVE-2008-5380.

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.
