Insecure database password generator
Platform: ownCloud Server
Versions: 4.0.14, 4.5.9, 5.0.4,
Risk level: Medium
Due to using “time()” as random source in the ownCloud installation routine, the entropy of the generated PostgreSQL database user password is very low and can be easily guessed.
This issue is inside the ownCloud setup routine and is not related to any PostgreSQL vulnerability.
- ownCloud Server < 5.0.4 (CVE-2013-1941)
- ownCloud Server < 4.5.9 (CVE-2013-1941)
- ownCloud Server < 4.0.14 (CVE-2013-1941)
It is recommended that all instances are upgraded to ownCloud Server 5.0.4, 4.5.9 or 4.0.14.
