Weakness
Reliance on Reverse DNS Resolution for a Security-Critical Action (CWE-350)
Summary

In PEPPERL+FUCHS WirelessHART-Gateway <= 3.0.8 serious issue exists, if the application is not externally accessible or uses IP-based access restrictions. Attackers can use DNS Rebinding to bypass any IP or firewall based access restrictions that may be in place, by proxying through their target's browser.

Weakness
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') (CWE-22)
Summary

In PEPPERL+FUCHS WirelessHART-Gateway <= 3.0.7 the filename parameter is vulnerable to unauthenticated path traversal attacks, enabling read access to arbitrary files on the server.

Weakness
Uncontrolled Resource Consumption (CWE-400)
Summary

jQuery 3.0.0-rc.1 is vulnerable to Denial of Service (DoS) due to removing a logic that lowercased attribute names. Any attribute getter using a mixed-cased name for boolean attributes goes into an infinite recursion, exceeding the stack call limit.

Weakness
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (CWE-79)
Summary

jQuery before 3.0.0 is vulnerable to Cross-site Scripting (XSS) attacks when a cross-domain Ajax request is performed without the dataType option, causing text/javascript responses to be executed.

Weakness
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (CWE-79)
Summary

jQuery before 1.9.0 is vulnerable to Cross-site Scripting (XSS) attacks. The jQuery(strInput) function does not differentiate selectors from HTML in a reliable fashion. In vulnerable versions, jQuery determined whether the input was HTML by looking for the '<' character anywhere in the string, giving attackers more flexibility when attempting to construct a malicious payload. In fixed versions, jQuery only deems the input to be HTML if it explicitly starts with the '<' character, limiting exploitability only to attackers who can control the beginning of a string, which is far less common.

Weakness
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (CWE-79)
Summary

jquery prior to 1.9.0 allows Cross-site Scripting attacks via the load method. The load method fails to recognize and remove some extra chars which results in the enclosed script logic to be executed.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (CWE-79)
Summary

In jQuery versions greater than or equal to 1.2 and before 3.5.0, passing HTML from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0.

Weakness
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (CWE-79)
Summary

jQuery before 3.4.0, as used in Drupal, Backdrop CMS, and other products, mishandles jQuery.extend(true, {}, ...) because of Object.prototype pollution. If an unsanitized source object contained an enumerable proto property, it could extend the native Object.prototype.

Weakness
Cleartext Storage of Sensitive Information in a Cookie (CWE-315)
Summary

Any cookie-stealing vulnerabilities within the application or browser would enable an attacker to steal the user's credentials to the PEPPERL+FUCHS WirelessHART-Gateway 3.0.9.

Weakness
Insufficiently Protected Credentials (CWE-522)
Summary

In PEPPERL+FUCHS WirelessHART-Gateway <= 3.0.9 a form contains a password field with autocomplete enabled. The stored credentials can be captured by an attacker who gains control over the user's computer. Therefore the user must have logged in at least once.

Weakness
Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') (CWE-444)
Summary

In PEPPERL+FUCHS WirelessHART-Gateway <= 3.0.8 a vulnerability may allow remote attackers to rewrite links and URLs in cached pages to arbitrary strings.

Weakness
Sensitive Cookie Without 'HttpOnly' Flag (CWE-1004)
Summary

In PEPPERL+FUCHS WirelessHART-Gateway 3.0.8 and 3.0.9 the HttpOnly attribute is not set on a cookie. This allows the cookie's value to be read or set by client-side JavaScript.

Weakness
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (CWE-79)
Summary

Cross-site scripting (XSS) vulnerability in jQuery before 1.6.3, when using location.hash to select elements, allows remote attackers to inject arbitrary web script or HTML via a crafted tag.

Weakness
Exposure of Sensitive Information to an Unauthorized Actor (CWE-200)
Summary

The jQuery framework exchanges data using JavaScript Object Notation (JSON) without an associated protection scheme, which allows remote attackers to obtain the data via a web page that retrieves the data through a URL in the SRC attribute of a SCRIPT element and captures the data using other JavaScript code, aka "JavaScript Hijacking."

References

Mitigation

An external protective measure is required.

Minimize network exposure for affected products and ensure that they are not accessible via the Internet.
Isolate affected products from the corporate network.
If remote access is required, use secure methods such as virtual private networks (VPNs).
