In Bootstrap 3.x before 3.4.0 and 4.x-beta before 4.0.0-beta.2, XSS is possible in the data-target attribute, a different vulnerability than CVE-2018-14041.

In Bootstrap before 4.1.2, XSS is possible in the collapse data-parent attribute.

In Bootstrap before 4.1.2, XSS is possible in the data-container property of tooltip.

A Reflected Cross Site Scripting flaw was found in all pki-core 10.x.x versions module from the pki-core server due to the CA Agent Service not properly sanitizing the certificate request page. An attacker could inject a specially crafted value that will be executed on the victim's browser.

A vulnerability was found in all pki-core 10.x.x versions, where the Key Recovery Authority (KRA) Agent Service did not properly sanitize recovery request search page, enabling a Reflected Cross Site Scripting (XSS) vulnerability. An attacker could trick an authenticated victim into executing specially crafted Javascript code.

A Reflected Cross Site Scripting vulnerability was found in all pki-core 10.x.x versions, where the pki-ca module from the pki-core server. This flaw is caused by missing sanitization of the GET URL parameters. An attacker could abuse this flaw to trick an authenticated user into clicking a specially crafted link which can execute arbitrary code when viewed in a browser.

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.

In Bootstrap before 3.4.1 and 4.3.x before 4.3.1, XSS is possible in the tooltip or popover data-template attribute.

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 3.5.0.

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 untrusted code. This problem is patched in jQuery 3.5.0.

In Dogtag PKI through 10.8.3, the pki.client.PKIConnection class did not enable python-requests certificate validation. Since the verify parameter was hard-coded in all request functions, it was not possible to override the setting. As a result, tools making use of this class, such as the pki-server command, may have been vulnerable to Person-in-the-Middle attacks in certain non-localhost use cases. This is fixed in 10.9.0-b1.

A flaw was found in the Key Recovery Authority (KRA) Agent Service in pki-core 10.10.5 where it did not properly sanitize the recovery ID during a key recovery request, enabling a reflected cross-site scripting (XSS) vulnerability. An attacker could trick an authenticated victim into executing specially crafted Javascript code.

In Apache Tomcat 9.0.0.M1 to 9.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99 the HTTP header parsing code used an approach to end-of-line parsing that allowed some invalid HTTP headers to be parsed as valid. This led to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered unlikely.

When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to Apache Tomcat. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP connection. If such connections are available to an attacker, they can be exploited in ways that may be surprising. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped with an AJP Connector enabled by default that listened on all configured IP addresses. It was expected (and recommended in the security guide) that this Connector would be disabled if not required. This vulnerability report identified a mechanism that allowed: - returning arbitrary files from anywhere in the web application - processing any file in the web application as a JSP Further, if the web application allowed file upload and stored those files within the web application (or the attacker was able to control the content of the web application by some other means) then this, along with the ability to process a file as a JSP, made remote code execution possible. It is important to note that mitigation is only required if an AJP port is accessible to untrusted users. Users wishing to take a defence-in-depth approach and block the vector that permits returning arbitrary files and execution as JSP may upgrade to Apache Tomcat 9.0.31, 8.5.51 or 7.0.100 or later. A number of changes were made to the default AJP Connector configuration in 9.0.31 to harden the default configuration. It is likely that users upgrading to 9.0.31, 8.5.51 or 7.0.100 or later will need to make small changes to their configurations.

A flaw was found in pki-core 10.9.0. A specially crafted POST request can be used to reflect a DOM-based cross-site scripting (XSS) attack to inject code into the search query form which can get automatically executed. The highest threat from this vulnerability is to data integrity.
