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).

Medium 6.9
Potential XSS vulnerability in jQuery
In jQuery versions greater than or equal to 1.0.3 and before 3.5.0, passing HTML containing <option> elements from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute unt…

Critical 9.8
In WirelessHART-Gateway versions 3.0.7 to 3.0.9 hard-coded credentials have been found
In PEPPERL+FUCHS WirelessHART-Gateway 3.0.7 to 3.0.9 the SSH and telnet services are active with hard-coded credentials.
-
High 7.5
Denial of Service in jquery
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.
-
High 7.5
A vulnerability may allow remote attackers to read arbitrary files on the server of the WirelessHART-Gateway
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.
-
High 7.5
A vulnerability in WirelessHART-Gateway <= 3.0.8 allows to bypass any IP or firewall based access restrictions through DNS rebinding
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 pl…

jQuery has a potential XSS vulnerability
In jQuery starting with 1.12.0 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…

Medium 6.1CVE-2012-6708 Public exploit
Cross-Site Scripting in jquery
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 '<…
-
Medium 6.1
Cross-Site Scripting (XSS) in jquery
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.
-
Medium 6.1
XSS in jQuery as used in Drupal, Backdrop CMS, and other products
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 Obj…
-
Medium 6.1CVE-2020-7656 Public exploit
Cross-Site Scripting in jquery
jquery prior to 1.9.0 allows Cross-site Scripting attacks via the load method. The load method fails to recognize and remove "<script>" HTML tags that contain a whitespace character, i.e: "</script >", which results in the enclosed script logic to be executed.
-
Medium 5.5
A vulnerability in WirelessHART-Gateway <= 3.0.9 could lead to information exposure of sensitive information
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.
-
Medium 5.5
In WirelessHART-Gateway versions 3.0.9 a vulnerability allows to read and write sensitive data in a cookie
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.
-
Medium 5.4
A vulnerability in WirelessHART-Gateway <= 3.0.8 may allow remote attackers to rewrite links and URLs in cached pages to arbitrary strings
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.
-
Medium 5.4
A vulnerability in WirelessHART-Gateway 3.0.8 it is possible to inject arbitrary JavaScript into the application's response
In PEPPERL+FUCHS WirelessHART-Gateway 3.0.8 it is possible to inject arbitrary JavaScript into the application's response.
-
Low 3.3
In WirelessHART-Gateway versions 3.0.8 and 3.0.9 the HttpOnly flag is missing in a cookie which allows client-side javascript to modify it
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.
