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

syslogd in the syslog subsystem in Apple iOS before 8 and Apple TV before 7 allows local users to change the permissions of arbitrary files via a symlink attack on an unspecified 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
Tvos Apple 6.0 6.0
Tvos Apple 6.0.1 6.0.1
Tvos Apple 6.0.2 6.0.2
Tvos Apple 6.1 6.1
Tvos Apple 6.1.1 6.1.1
Tvos Apple 6.1.2 6.1.2
Tvos Apple * 6.2

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.
