A deserialization flaw was discovered in Apache Tomcat's use of a FileStore. An attacker can exploit the flaw if all of the following are true: An attacker is able to control the contents and name of a file on the server. The server is configured to use the PersistenceManager with a FileStore. The PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker-provided object to be deserialized. The attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over. If all these conditions are true, the attacker can use a specifically crafted request to trigger Remote Code Execution through deserialization of the file under their control.

This flaw affects the following Tomcat versions: 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54, and 7.0.0 to 7.0.103.

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.

FasterXML jackson-databind 2.x before 2.9.10.6 mishandles the interaction between serialization gadgets and typing, related to br.com.anteros.dbcp.AnterosDBCPDataSource (aka Anteros-DBCP).

Pivotal Spring Framework is vulnerable to a denial of service, caused by improper handling of range request by the ResourceHttpRequestHandler. By adding a range header with a high number of ranges, a remote attacker could exploit this vulnerability to cause a denial of service condition.

Pivotal Spring Framework is vulnerable to cross-site tracing, caused by a flaw in the HiddenHttpMethodFilter in Spring MVC. By persuading a victim to visit a specially-crafted Web site, an attacker could exploit this vulnerability to cause the victim's browser to invoke a TRACE request to return sensitive header information including cookies or authentication data from third-party domains.

A flaw was found in dom4j library. By using the default SaxReader() provided by Dom4J, external DTDs and External Entities are allowed, resulting in a possible XXE.

A flaw was found in Spring Security in combination with Spring Framework versions prior to 5.0.6 contains an authorization bypass when using method security. An unauthorized malicious user can gain unauthorized access to methods that should be restricted.

A flaw was found in Apache Groovy. Groovy makes use of a method for creating temporary directories which is not suitable for security-sensitive contexts and allows for sensitive information leakage. The highest threat from this vulnerability is to data confidentiality.

Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding; and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.

For Eclipse Jetty versions 9.4.37-9.4.42, 10.0.1-10.0.5 & 11.0.1-11.0.5, URIs can be crafted using some encoded characters to access the content of the WEB-INF directory and/or bypass some security constraints.

Apache Ant 1.1 to 1.9.14 and 1.10.0 to 1.10.7 uses the default temporary directory identified by the Java system property java.io.tmpdir for several tasks and may thus leak sensitive information. The fixcrlf and replaceregexp tasks also copy files from the temporary directory back into the build tree allowing an attacker to inject modified source files into the build process.

A flaw was discovered in FasterXML jackson-databind, where it would permit polymorphic deserialization of malicious objects using the ehcache and logback JNDI gadgets when used in conjunction with polymorphic type handling methods such as enableDefaultTyping() or when @JsonTypeInfo is using Id.CLASS or Id.MINIMALCLASS or in any other way which ObjectMapper.readValue might instantiate objects from unsafe sources. An attacker could use this flaw to execute arbitrary code.
