SQL injection vulnerability in modules/journal/search.php in the Journal module in Francisco Burzi PHP-Nuke 7.9 and earlier allows remote attackers to execute arbitrary SQL commands via the forwhat parameter.
Multiple SQL injection vulnerabilities in the (1) ratearticle and (2) ratecomplete functions in modules/News/index.php in the News module in Francisco Burzi PHP-Nuke 7.9 and earlier, when magicquotesgpc is disabled, allow remote attackers to execute arbitrary SQL commands via the sid parameter.
Multiple SQL injection vulnerabilities in modules.php in PHP-Nuke 7.8, when magicquotesgpc 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 WebLinks module.
SQL injection vulnerability in the YourAccount module in PHP-Nuke 7.8 might allows remote attackers to execute arbitrary SQL commands via the userid parameter in the YourHome functionality. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.
Cross-site scripting (XSS) vulnerability in the YourAccount module in PHP-Nuke 7.8 might allows remote attackers to inject arbitrary HTML and web script via the ublock parameter, which is saved in the user's personal menu. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information. In addition, it is unclear whether this issue is a vulnerability, since it is related to the user's personal menu, which presumably is not modifiable by others.
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 (HTTPUSERAGENT), which allows remote attackers to bypass CAPTCHA controls by fixing the User Agent, performing a valid challenge/response, then replaying that pair in the randomnum and gfxcheck parameters.
SQL injection vulnerability in PHP-Nuke before 7.8 Patched 3.2 allows remote attackers to execute arbitrary SQL commands via encoded /%2a (/) sequences in the query string, which bypasses regular expressions that are intended to protect against SQL injection, as demonstrated via the kala parameter.
Cross-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.
Cross-site request forgery (CSRF) vulnerability in admin.php in Francisco Burzi PHP-Nuke allows remote attackers to add administrative accounts via an AddAuthor action with modified addname and addradminsuper parameters.
