[原文]Multiple cross-site scripting (XSS) vulnerabilities in PHP-Nuke 6.0 to 7.3 allow remote attackers to inject arbitrary web script or HTML via the (1) eid parameter or (2) query parameter to the Encyclopedia module, (3) preview_review function in the Reviews module as demonstrated by the url, cover, rlanguage, and hits parameters, or (4) savecomment function in the Reviews module, as demonstrated using the uname parameter. NOTE: the Faq/categories and Encyclopedia/ltr issues are already covered by CVE-2005-1023.
PHP-Nuke is prone to multiple vulnerabilities. The issues result from insufficient sanitization of user-supplied data. The following specific issues can affect the application:
PHP-Nuke is prone to multiple cross-site scripting vulnerabilities. These issues affect the 'Faq', 'Encyclopedia' and 'Reviews' modules.
These cross-site scripting issues could permit a remote attacker to create a malicious URI link that includes hostile HTML and script code. If a user follows the malicious link, the attacker-supplied code executes in the Web browser of the victim computer.
PHP-Nuke is prone to an SQL Injection Vulnerability. Again the issue is due to a failure of the application to properly sanitize user-supplied input. The problem presents itself when SQL syntax is passed through the a parameter of the 'Reviews' module.
As a result of this issue an attacker could modify the logic and structure of database queries.
Finally a remote denial of service vulnerability is reported to exist in the score subsystem of the 'Review' module of PHP-Nuke, it is reported that a large number supplied as a value for a parameter passed to the 'Reviews' module will deny service to legitimate PHP-Nuke users.

PHP-Nuke Encyclopedia Module Multiple Function XSS
Remote / Network Access
Loss of Integrity
PHP-Nuke contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate ltr, eid, and query variables upon submission to the Encyclopedia module. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
