Apache Tomcat: Apache Tomcat: Information disclosure due to improper encoding in JsonAccessLogValve

A flaw was found in the JsonAccessLogValve component of Apache Tomcat. This improper encoding or escaping of output vulnerability could allow an attacker to inject specially crafted data into log files. This could lead to information disclosure or other unintended consequences when the logs are...

Apache Tomcat: Apache Tomcat: Information disclosure via sensitive data in log files

A flaw was found in Apache Tomcat. The cloud membership for clustering component was vulnerable to the insertion of sensitive information into log files. This vulnerability could lead to the exposure of the Kubernetes bearer token, which is a credential used for authentication within a Kubernetes...

tomcat: Apache Tomcat: Denial of Service due to uncontrolled resource allocation

In Apache Tomcat, no limit was enforced on the request body for WebDAV LOCK or PROPFIND requests which were available to unauthenticated users. This allows a remote attacker to consume excessive resources, leading to Denial of Service DoS, making the affected system unavailable to legitimate user...

tomcat-catalina: Apache Tomcat: Improper Handling of Case Sensitivity in LockOutRealm

In Apache Tomcat, LockOutRealm mishandled case sensitivity in usernames, resulting in less effective blocking of brute force attacks...

tomcat-coyote: tomcat: Improper Authorization allows security bypass

In Apache Tomcat, when multiple security constraints defined an HTTP method constraint for the same extension pattern, only the first method constraint was applied. A remote attacker could exploit this to bypass intended security restrictions for information or actions within the application...

Apache Tomcat: Apache Tomcat: Incorrect control flow in rewrite valve allows unexpected rule processing

A flaw was found in Apache Tomcat's rewrite valve. This vulnerability involves an incorrect control flow implementation where, during the processing of rewrite rules, if the first condition in an OR chain matched, subsequent non-OR conditions were unexpectedly skipped. This can lead to unintended...

tomcat: Apache Tomcat: Misleading security logs due to incorrect control flow

A flaw was found in Apache Tomcat. Due to an always-incorrect control flow implementation, special roles and empty authorization constraints were not accurately included when the effective web.xml configuration was logged. This could lead to a security oversight where administrators might...

tomcat: Apache Tomcat: Replay attack via improper authentication in EncryptionInterceptor

A flaw was found in Apache Tomcat. An improper authentication vulnerability in the EncryptionInterceptor component allows a remote attacker to perform a replay attack. This could lead to unauthorized access or manipulation of data within the cluster component...

tomcat-coyote: Apache Tomcat: HTTP/2 request headers not validated

Apache Tomcat did not validate HTTP/2 request headers, triggering unexpected application behavior, as applications may presume that header values exposed through the Servlet API would be valid...

tomcat: Apache Tomcat: Authentication bypass via missing critical step in JNDIRealm GSSAPI configuration

A flaw was found in Apache Tomcat. When the JNDIRealm was configured to authenticate binds using GSSAPI, an attacker could exploit a missing critical step in the authentication process. This allowed the attacker to bypass password verification and authenticate without providing the correct...

tomcat: Apache Tomcat: Security constraint bypass via improper URL encoding in rewrite valve

A flaw was found in Apache Tomcat. This vulnerability, located in the rewrite valve, is due to improper handling of URL encoding hex encoding. A remote attacker could exploit this to bypass security constraints in certain configurations, potentially gaining unauthorized access or performing actio...

tomcat: Apache Tomcat: Error condition not handled when configuring CRLs

A flaw was found in Apache Tomcat. When configuring Certificate Revocation Lists CRLs for a FFM presumably a specific type of connector, the system fails to detect and act upon an error condition. This oversight could lead to unexpected behavior or a security bypass, as the intended security...

tomcat: Apache Tomcat: Insufficient documentation for EncryptInterceptor may lead to insecure configurations

A flaw was found in Apache Tomcat. Insufficient technical documentation regarding the secure configuration of the EncryptInterceptor component may lead to deployments with insecure settings. This vulnerability could allow an attacker to exploit misconfigurations that arise from unclear guidance,...
