A flaw was found in the Apache Log4j logging library 2.x. when the logging configuration uses a non-default Pattern Layout with a Context Lookup. Attackers with control over Thread Context Map (MDC) input data can craft malicious input data that contains a recursive lookup and can cause Denial of Service.

A flaw was found in the Apache Xerces Java (XercesJ) XML parser when handling specially crafted XML document payloads. This issue causes the XercesJ XML parser to wait in an infinite loop, which may consume system resources for a prolonged duration, leading to a denial of service condition.

A vulnerability was found in Hibernate-Validator. The SafeHtml validator annotation fails to properly sanitize payloads consisting of potentially malicious code in HTML comments and instructions. This vulnerability can result in an XSS attack.

Impact Accepting the value of various Text options of the Datepicker widget from untrusted sources may execute untrusted code. For example, initializing the datepicker in the following way: js $( "#datepicker" ).datepicker( { showButtonPanel: true, showOn: "both", closeText: "<script>doEvilThing( 'closeText XSS' )</script>", currentText: "<script>doEvilThing( 'currentText XSS' )</script>", prevText: "<script>doEvilThing( 'prevText XSS' )</script>", nextText: "<script>doEvilThing( 'nextText XSS' )</script>", buttonText: "<script>doEvilThing( 'buttonText XSS' )</script>", appendText: "<script>doEvilThing( 'appendText XSS' )</script>", } ); will call doEvilThing with 6 different parameters coming from all Text options.

Patches The issue is fixed in jQuery UI 1.13.0. The values passed to various Text options are now always treated as pure text, not HTML.

Workarounds A workaround is to not accept the value of the Text options from untrusted sources.

Impact Accepting the value of the of option of the .position() util from untrusted sources may execute untrusted code. For example, invoking the following code: js $( "#element" ).position( { my: "left top", at: "right bottom", of: "<img onerror='doEvilThing()' src='/404' />", collision: "none" } ); will call the doEvilThing() function.

Patches The issue is fixed in jQuery UI 1.13.0. Any string value passed to the of option is now treated as a CSS selector.

Workarounds A workaround is to not accept the value of the of option from untrusted sources.

Impact Accepting the value of the altField option of the Datepicker widget from untrusted sources may execute untrusted code. For example, initializing the datepicker in the following way: js $( "#datepicker" ).datepicker( { altField: "<img onerror='doEvilThing()' src='/404' />", } ); will call the doEvilThing function.

All versions of Apache Santuario - XML Security for Java prior to 2.2.3 and 2.1.7 are vulnerable to an issue where the "secureValidation" property is not passed correctly when creating a KeyInfo from a KeyInfoReference element. This allows an attacker to abuse an XPath Transform to extract any local .xml files in a RetrievalMethod element.

In Apache Commons IO before 2.7, When invoking the method FileNameUtils.normalize with an improper input string, like "//../foo", or "\\..\foo", the result would be the same value, thus possibly providing access to files in the parent directory, but not further above (thus "limited" path traversal), if the calling code would use the result to construct a path value.

In the Jakarta Expression Language implementation 3.0.3 and earlier, a bug in the ELParserTokenManager enables invalid EL expressions to be evaluated as if they were valid.

CiphertextHeader.java in Cryptacular 1.2.3, as used in Apereo CAS and other products, allows attackers to trigger excessive memory allocation during a decode operation, because the nonce array length associated with "new byte" may depend on untrusted input within the header of encoded data.

In version 2.0.3 Apache Santuario XML Security for Java, a caching mechanism was introduced to speed up creating new XML documents using a static pool of DocumentBuilders. However, if some untrusted code can register a malicious implementation with the thread context class loader first, then this implementation might be cached and re-used by Apache Santuario - XML Security for Java, leading to potential security flaws when validating signed documents, etc. The vulnerability affects Apache Santuario - XML Security for Java 2.0.x releases from 2.0.3 and all 2.1.x releases before 2.1.4.

In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive serialized log events from another application, a specially crafted binary payload can be sent that, when deserialized, can execute arbitrary code.

Apache Batik 1.13 is vulnerable to server-side request forgery, caused by improper input validation by the NodePickerPanel. By using a specially-crafted argument, an attacker could exploit this vulnerability to cause the underlying server to make arbitrary GET requests.

A flaw was found in Guava that creates temporary directories with default permissions similar to /tmp. This issue may allow local users access, possibly permitting information exposure.

A flaw was found in Hibernate Validator version 6.1.2.Final. A bug in the message interpolation processor enables invalid EL expressions to be evaluated as if they were valid. This flaw allows attackers to bypass input sanitation (escaping, stripping) controls that developers may have put in place when handling user-controlled data in error messages.

A deserialization flaw was found in Apache log4j 1.2.x. While reading serialized log events, they are improperly deserialized.

Note this is the same as CVE-2020-9493 which identified a deserialization issue in Apache Chainsaw. Prior to Chainsaw V2.0, Chainsaw was a component of Apache Log4j 1.2.x.

A flaw was found in the Java logging library Apache Log4j in version 1.x. JDBCAppender in Log4j 1.x is vulnerable to SQL injection in untrusted data. This allows a remote attacker to run SQL statements in the database if the deployed application is configured to use JDBCAppender with certain interpolation tokens.

A flaw was found in the Java logging library Apache Log4j in version 1.x. JMSSink in Log4j 1.x is vulnerable to deserialization of untrusted data. This allows a remote attacker to execute code on the server if JMSSink is deployed and has been configured to perform JNDI requests.

Impact Passing HTML containing <option> elements from untrusted sources - even after sanitizing them - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code.

Patches This problem is patched in jQuery 3.5.0.

Workarounds To workaround this issue without upgrading, use DOMPurify with its SAFEFORJQUERY option to sanitize the HTML string before passing it to a jQuery method.
