The CAPTCHA functionality in php-Nuke 6.0 through 7.9 uses fixed challenge/response pairs that only vary once per day based on the User Agent (HTTP_USER_AGENT), which allows remote attackers to bypass CAPTCHA controls by fixing the User Agent, performing a valid challenge/response, then replaying that pair in the random_num and gfx_check parameters.

Security Vulnerability Index
Page 5 / 20Cross-site scripting (XSS) vulnerability in header.php in PHP-Nuke 6.0 to 7.8 allows remote attackers to inject arbitrary web script or HTML via the pagetitle parameter.
Multiple SQL injection vulnerabilities in modules.php in PHP-Nuke 7.8, when magic_quotes_gpc is disabled, allow remote attackers to execute arbitrary SQL commands via the (1) name, (2) sid, and (3) pid parameters in a POST request, which bypasses security checks that are performed for GET requests.
Interpretation conflict in includes/mainfile.php in PHP-Nuke 7.9 and later allows remote attackers to perform cross-site scripting (XSS) attacks by replacing the ">" in the tag with a "<", which bypasses the regular expressions that sanitize the data, but is automatically corrected by many web browsers. NOTE: it could be argued that this vulnerability is due to a design limitation of many web browsers; if so, then this should not be treated as a vulnerability in PHP-Nuke.
Multiple SQL injection vulnerabilities in the Search module in PHP-Nuke 7.8, and possibly other versions before 7.9 with patch 3.1, allows remote attackers to execute arbitrary SQL commands, as demonstrated via the query parameter in a stories type.
Multiple SQL injection vulnerabilities in PHP-Nuke 7.8 allow remote attackers to modify SQL queries and execute arbitrary PHP code via (1) the username parameter in the Your Account page, (2) the url parameter in the Downloads module, and (3) the description parameter in the Web_Links module.
Multiple unspecified vulnerabilities in the WYSIWYG editor in PHP-Nuke before 7.9 Final have unknown impact and attack vectors.
PHP-Nuke 7.6 and earlier allows remote attackers to obtain sensitive information via a direct request to (1) ipban.php, (2) db.php, (3) lang-norwegian.php, (4) lang-indonesian.php, (5) lang-greek.php, (6) a request to Web_Links with the portuguese language (lang-portuguese.php), (7) a request to Web_Links with the indonesian language (lang-indonesian.php), (8) a request to the survey module with the indonesian language (lang-indonesian.php), (9) a request to the Reviews module with the portuguese language, or (10) a request to the Journal module with the portuguese language, which reveal the path in an error message.
modules.php in PHP-Nuke 6.x to 7.6 allows remote attackers to obtain sensitive information via a direct request to (1) my_headlines, (2) userinfo, or (3) search, which reveals the path in a PHP error message.
Multiple cross-site scripting (XSS) vulnerabilities in PHP-Nuke 6.x through 7.6 allow remote attackers to inject arbitrary web script or HTML via the (1) username parameter in the Your_Account module, (2) avatarcategory parameter in the Your_Account module, or (3) lid parameter in the Downloads module.
