`Zend_Json_Encoder` was not taking into account the solidus character (/) during encoding, leading to incompatibilities with the JSON specification, and opening the potential for XSS or HTML injection attacks when returning HTML within a JSON string.

zend-diactoros (and, by extension, Expressive), zend-http (and, by extension, Zend Framework MVC projects), and zend-feed (specifically, its PubSubHubbub sub-component) each contain a potential URL rewrite exploit. In each case, marshaling a request URI includes logic that introspects HTTP request headers that are specific to a given server-side URL rewrite mechanism. When these headers are present on systems not running the specific URL rewriting mechanism, the logic would still trigger, allowing a malicious client or proxy to emulate the headers to request arbitrary content.

In mid-March, 2010, the Dojo Foundation issued a Security Advisory indicating potential security issues with specific files in Dojo Toolkit. Details of the advisory may be found on the Dojo website: http://dojotoolkit.org/blog/post/dylan/2010/03/dojo-security-advisory/ In particular, several files in the Dojo tree were identified as having potential exploits, and the Dojo team also advised disabling or removing any PHP scripts in the tree when deploying to production.

Numerous components utilizing PHP's DOMDocument, SimpleXML, and xml_parse functionality are vulnerable to two types of attacks: - XML eXternal Entity (XXE) Injection attacks. The above mentioned extensions are insecure by default, allowing external entities to be specified by adding a specific DOCTYPE element to XML documents and strings. By exploiting this vulnerability an application may be coerced to open arbitrary files and/or TCP connections. - XML Entity Expansion (XEE) vectors, leading to Denial of Service vectors. XEE attacks occur when the XML DOCTYPE declaration includes XML entity definitions that contain either recursive or circular references; this leads to CPU and memory consumption, making Denial of Service exploits trivial to implement.

Zend_XmlRpc is vulnerable to XML eXternal Entity (XXE) Injection attacks. The SimpleXMLElement class (SimpleXML PHP extension) is used in an insecure way to parse XML data. External entities can be specified by adding a specific DOCTYPE element to XML-RPC requests. By exploiting this vulnerability an application may be coerced to open arbitrary files and/or TCP connections.

`Zend_Dom`, `Zend_Feed`, `Zend_Soap`, and `Zend_XmlRpc` are vulnerable to XML Entity Expansion (XEE) vectors, leading to Denial of Service vectors. XEE attacks occur when the XML DOCTYPE declaration includes XML entity definitions that contain either recursive or circular references; this leads to CPU and memory consumption, making Denial of Service exploits trivial to implement.

`Zend_Filter_StripTags` is a filtering class analogous to PHP's `strip_tags()` function. In addition to stripping HTML tags and selectively keeping those provided in a whitelist, it also provides the ability to whitelist specific attributes to retain per whitelisted tag. The reporter discovered that attributes that contained whitespace, and in paricular, line breaks, surrounding the attribute assignment operator would not be stripped, regardless of whether or not they were whitelisted. As examples of input affected: ``` <!-- newlines before and/or after assignment: --> <a href="http://framework.zend.com/issues" onclick = "alert('Broken'); return false;">Issues</a> ``` When passed to the following code: ``` $filter = new Zend_Filter_StripTags(array('a' => array('href'))); $value = $filter->($html); ``` then the "onclick" attribute would remain, even though it was not specified in the tag's whitelist. This could open potential cross-site scripting attack (XSS) vectors. ## Recommendati...
