11123
Netatalk etc2ps.sh Symlink Arbitrary File Modification
Local Access Required Race Condition
Loss of Integrity
Exploit Public

- 漏洞描述

The Netatalk etc2ps.sh script contains a flaw that may allow a malicious user to overwrite files with the permissions of the user running the script. The issue is due to the fact that the script creates world-writeable symlinks with predictable filenames; attackers can simply change the file the symlink points to in order to overwrite files with their own data, resulting in a loss of integrity.

- 漏洞讨论

Netatalk is affected by an insecure temporary file creation vulnerability. This issue is due to a design error that causes the application to fail to verify the existance of a file before writing to it.

An attacker may leverage this issue to overwrite arbitrary files with the privileges of an unsuspecting user that activates the vulnerable application. Reportedly this issue is unlikely to facilitate privilege escalation.

Versions of Netatalk prior to version 1.6.4a are reported to be affected by this issue.

- 漏洞利用

No exploit is required to leverage this issue.
