[原文]Multiple cross-site scripting (XSS) vulnerabilities in Andy's PHP Knowledgebase (aphpkb) 0.57 allow remote attackers to inject arbitrary web script or HTML via the (1) keyword_list parameter to (a) index.php; (2) title, (3) article, (4) author, and (5) keywords parameters to (b) submit_article.php; and (6) Question, (7) Name, and (8) Email parameters to (c) submit_question.php.
Andy's PHP Knowledgebase (aphpkb) contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'keyword_list' variable upon submission to the index.php script. 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.
Upgrade to version 0.59 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
security curmudgeon is credited with the discovery of these vulnerabilities.

Andy's PHP Knowledgebase is prone to multiple cross-site scripting vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input.
An attacker may leverage these issues to have arbitrary script code executed in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.
This issue can be exploited through a web client.
