Vulnerabilities



Last Update
Sept. 8, 2021, 9:29 a.m.
Weakness
Use of Hard-coded Credentials (CWE-798)
Summary
In PEPPERL+FUCHS WirelessHART-Gateway 3.0.7 to 3.0.9 the SSH and telnet services are active with hard-coded credentials.
Last Update
Nov. 17, 2022, 1:09 p.m.
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.
Last Update
Sept. 8, 2021, 9:27 a.m.
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.

Last Update
Sept. 8, 2021, 9:29 a.m.
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.
Last Update
Sept. 8, 2021, 9:27 a.m.
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.

Last Update
Sept. 8, 2021, 9:28 a.m.
Weakness
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (CWE-79)
Summary

jQuery 1.4.2 allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to use of the text method inside after.

Last Update
Sept. 8, 2021, 9:28 a.m.
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.

Last Update
Feb. 18, 2020, 8:42 a.m.
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.
Last Update
Nov. 17, 2022, 1:09 p.m.
Weakness
Improper Neutralization of Input During Web Page Generation (Cross-site Scripting) (CWE-79)
Summary
In PEPPERL+FUCHS WirelessHART-Gateway 3.0.8 it is possible to inject arbitrary JavaScript into the application's response.
Last Update
Sept. 8, 2021, 9:27 a.m.
Weakness
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (CWE-79)
Summary

In jQuery versions greater than or equal to 1.0.3 and before 3.5.0, passing HTML containingelements 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.

Last Update

Weakness
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.

Last Update
Oct. 19, 2021, 10:19 a.m.
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.

Last Update
Nov. 17, 2022, 1:09 p.m.
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.
Last Update
Nov. 17, 2022, 1:09 p.m.
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.
Last Update
Nov. 17, 2022, 1:09 p.m.
Weakness
Inconsistent Interpretation of HTTP Requests ('HTTP Request 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.
Last Update
Sept. 8, 2021, 9:28 a.m.
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."

Last Update
Sept. 8, 2021, 9:28 a.m.
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.

Last Update
Nov. 17, 2022, 1:09 p.m.
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.
Last Update
Sept. 8, 2021, 9:28 a.m.
Weakness
Cryptographic Issues (CWE-310)
Summary

The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and other products, do not properly consider timing side-channel attacks on a MAC check requirement during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, aka the "Lucky Thirteen" issue.

Impact

Pepperl+Fuchs analyzed and identified affected devices.
Remote attackers may exploit the vulnerability sending specially crafted packages that may result in a denial-of-service condition or code execution.

Solution

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).
