openexec in OpenBase SQL before 10.0.1 allows local users to create arbitrary files via a symlink attack on the /tmp/output file, a different vulnerability than CVE-2006-5328.
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 |
|---|---|---|---|
| Openbase | Openbase_international_ltd | 7.0.15 (including) | 7.0.15 (including) |
| Openbase | Openbase_international_ltd | 8.0.4 (including) | 8.0.4 (including) |
| Openbase | Openbase_international_ltd | 9.1.5 (including) | 9.1.5 (including) |

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.
