Description


Javier Fernandez-Sanguino Pena has reported a vulnerability in DHIS Tools, which can be exploited by malicious, local users to perform certain actions on a vulnerable system with escalated privileges.

The vulnerability is caused due to temporary files being created insecurely in the temporary directory by "register-p.sh" and "register-q.sh". This can be exploited via symlink attacks to overwrite arbitrary files with the privileges of the user running the affected script.

Successful exploitation requires that the malicious user is able to write to the temporary directory.

The vulnerability has been reported in version 5.0. Other versions may also be affected.


Solution:
Grant only trusted users access to affected systems.
