Vulnerability from github – Published: 2023-11-08 14:51 – Updated: 2023-11-08 14:51
VLAI
Summary
XWiki Platform vulnerable to reflected cross-site scripting through revision parameter in content menu
Details

Impact

XWiki is vulnerable to reflected cross-site scripting (RXSS) via the rev parameter that is used in the content of the content menu without escaping. If an attacker can convince a user to visit a link with a crafted parameter, this allows the attacker to execute arbitrary actions in the name of the user, including remote code (Groovy) execution in the case of a user with programming right, compromising the confidentiality, integrity and availability of the whole XWiki installation.

The vulnerability can be demonstrated by opening <xwiki-host>/xwiki/bin/view/Main/?rev=xar%3Aorg.xwiki.platform%3Axwiki-platform-distribution-flavor-common%2F15.5%25%25%22%3e%3cscript%3ealert(1)%3c%2fscript%3e where <xwiki-host> is the URL of your XWiki installation. If an alert is displayed, the installation is vulnerable.

Patches

This has been patched in XWiki 15.6 RC1, 15.5.1 and 14.10.14.

Workarounds

The patch can be manually applied without upgrading (or restarting) the instance.

Vulnerability from github – Published: 2025-10-15 09:30 – Updated: 2025-10-15 09:30
VLAI
Details

The WPBakery Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the vc_custom_heading shortcode in all versions up to, and including, 8.6.1. This is due to insufficient restriction of allowed HTML tags and improper sanitization of user-supplied attributes in the font_container parameter. This makes it possible for authenticated attackers with contributor-level access or higher to inject arbitrary web scripts in posts that will execute whenever a user accesses an injected page via the vc_custom_heading shortcode with malicious tag and text attributes granted they have access to use WPBakery shortcodes.

Summary
TabberNeue vulnerable to Stored XSS through wikitext
Details

Summary

Arbitrary HTML can be inserted into the DOM by inserting a payload into any allowed attribute of the <tabber> tag.

Details

The args provided within the wikitext as attributes to the <tabber> tag are passed to the TabberComponentTabs class: https://github.com/StarCitizenTools/mediawiki-extensions-TabberNeue/blob/3a23b703ce36cfc4128e7921841f68230be4059a/includes/Tabber.php#L76

In TabberComponentTabs, the attributes are validated before being supplied to the Tabs template. https://github.com/StarCitizenTools/mediawiki-extensions-TabberNeue/blob/3a23b703ce36cfc4128e7921841f68230be4059a/includes/Components/TabberComponentTabs.php#L15-L31 However, the validation is insufficient. What Sanitizer::validateTagAttributes does is call validateAttributes, which

     * - Discards attributes not on the given list
     * - Unsafe style attributes are discarded
     * - Invalid id attributes are re-encoded

However, the attribute values are expected to be escaped when inserted into HTML.

The attribute values are then inserted into HTML without being escaped: https://github.com/StarCitizenTools/mediawiki-extensions-TabberNeue/blob/3a23b703ce36cfc4128e7921841f68230be4059a/includes/templates/Tabs.mustache#L1

PoC

XSS through attributes:

  1. Go to Special:ExpandTemplates and insert the following wikitext:
<tabber class='test123" onmouseenter="alert(1)"'>
|-|First Tab Title=
First tab content goes here.
</tabber>
  1. Press "OK"
  2. Hover over the tabber

image

XSS through script tags:

  1. Go to Special:ExpandTemplates and insert the following wikitext:
<tabber class='test123"&gt;&lt;script&gt;alert(2)&lt;/script&gt;'>
|-|First Tab Title=
First tab content goes here.
</tabber>
  1. Press "OK" image

Impact

Arbitrary HTML can be inserted into the DOM by any user, allowing for JavaScript to be executed.

Mitigation
Implementation

Carefully check each input parameter against a rigorous positive specification (allowlist) defining the specific characters and format allowed. All input should be neutralized, not just parameters that the user is supposed to specify, but all data in the request, including hidden fields, cookies, headers, the URL itself, and so forth. A common mistake that leads to continuing XSS vulnerabilities is to validate only fields that are expected to be redisplayed by the site. We often encounter data from the request that is reflected by the application server or the application that the development team did not anticipate. Also, a field that is not currently reflected may be used by a future developer. Therefore, validating ALL parts of the HTTP request is recommended.

Mitigation MIT-30.1
Implementation

Strategy: Output Encoding

  • Use and specify an output encoding that can be handled by the downstream component that is reading the output. Common encodings include ISO-8859-1, UTF-7, and UTF-8. When an encoding is not specified, a downstream component may choose a different encoding, either by assuming a default encoding or automatically inferring which encoding is being used, which can be erroneous. When the encodings are inconsistent, the downstream component might treat some character or byte sequences as special, even if they are not special in the original encoding. Attackers might then be able to exploit this discrepancy and conduct injection attacks; they even might be able to bypass protection mechanisms that assume the original encoding is also being used by the downstream component.
  • The problem of inconsistent output encodings often arises in web pages. If an encoding is not specified in an HTTP header, web browsers often guess about which encoding is being used. This can open up the browser to subtle XSS attacks.
Mitigation MIT-43
Implementation

With Struts, write all data from form beans with the bean's filter attribute set to true.

Mitigation MIT-31
Implementation

Strategy: Attack Surface Reduction

To help mitigate XSS attacks against the user's session cookie, set the session cookie to be HttpOnly. In browsers that support the HttpOnly feature (such as more recent versions of Internet Explorer and Firefox), this attribute can prevent the user's session cookie from being accessible to malicious client-side scripts that use document.cookie. This is not a complete solution, since HttpOnly is not supported by all browsers. More importantly, XmlHttpRequest and other powerful browser technologies provide read access to HTTP headers, including the Set-Cookie header in which the HttpOnly flag is set.

CAPEC-18: XSS Targeting Non-Script Elements

This attack is a form of Cross-Site Scripting (XSS) where malicious scripts are embedded in elements that are not expected to host scripts such as image tags (<img>), comments in XML documents (< !-CDATA->), etc. These tags may not be subject to the same input validation, output validation, and other content filtering and checking routines, so this can create an opportunity for an adversary to tunnel through the application's elements and launch a XSS attack through other elements. As with all remote attacks, it is important to differentiate the ability to launch an attack (such as probing an internal network for unpatched servers) and the ability of the remote adversary to collect and interpret the output of said attack.

CAPEC-193: PHP Remote File Inclusion

In this pattern the adversary is able to load and execute arbitrary code remotely available from the application. This is usually accomplished through an insecurely configured PHP runtime environment and an improperly sanitized "include" or "require" call, which the user can then control to point to any web-accessible file. This allows adversaries to hijack the targeted application and force it to execute their own instructions.

CAPEC-32: XSS Through HTTP Query Strings

An adversary embeds malicious script code in the parameters of an HTTP query string and convinces a victim to submit the HTTP request that contains the query string to a vulnerable web application. The web application then procedes to use the values parameters without properly validation them first and generates the HTML code that will be executed by the victim's browser.

CAPEC-86: XSS Through HTTP Headers

An adversary exploits web applications that generate web content, such as links in a HTML page, based on unvalidated or improperly validated data submitted by other actors. XSS in HTTP Headers attacks target the HTTP headers which are hidden from most users and may not be validated by web applications.
