CVE-2007-0205: Alexphpteam Alex Guestbook

High severity, CVSS 7.5. EPSS: 3.4% chance of exploitation in the next 30 days.

Directory traversal vulnerability in admin/skins.php for @lex Guestbook 4.0.2 and earlier allows remote attackers to create files in arbitrary directories via ".." sequences in the (1) aj_skin and (2) skin_edit parameters. NOTE: this can be leveraged for file inclusion by creating a skin file in the lang directory, then referencing that file via the lang parameter to index.php, which passes a sanity check in livre_include.php.

Affected products

• Alexphpteam Alex Guestbook: version 3.12 only; version 3.13 only; version 4.0.1 only; version 4.0.2 only
