underConstruction <= 1.21 - Authenticated (Administrator+) Stored Cross-Site Scripting

underConstruction: Currently marked unpatched

Affected versions: *-1.21

Vulnerability type: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Affected software, patched versions and attribution

The underConstruction plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.21 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

underConstruction <= 1.18 - Reflected Cross-Site Scripting

underConstruction: Currently marked unpatched

Affected versions: *-1.18

Vulnerability type: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Affected software, patched versions and attribution

The underConstruction plugin <= 1.18 for WordPress echoes out the raw value of `$GLOBALS['PHP_SELF']` in the ucOptions.php file. On certain configurations including Apache+modPHP, this makes it possible to use it to perform a reflected Cross-Site Scripting attack by injecting malicious code in the request path.
