tomcat-coyote: Apache Tomcat: Authentication bypass via digest authentication

A flaw was found in Apache Tomcat. When DIGEST authentication was configured, any user not known to the configured Realm would be authenticated if they presented the password "null". This allows a remote attacker to bypass security controls...

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: 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: Improper Authorization Allows Security Constraint Bypass

A flaw was found in Apache Tomcat where access control rules for the default servlet are improperly handled. An attacker can exploit this issue to bypass specific HTTP method restrictions, potentially gaining unauthorized access to protected application resources...

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: 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...

Apache Tomcat: Apache Tomcat: Improper Input Validation vulnerability due to incomplete fix

A flaw was found in Apache Tomcat. This improper input validation vulnerability stems from an incomplete fix for a previous security issue CVE-2025-66614. This flaw may allow an attacker to bypass security controls or cause unexpected behavior within the application...

tomcat: Apache Tomcat: Information disclosure via AJP secret timing discrepancy

A flaw was found in Apache Tomcat. The AJP secret was comparable in non-constant time, allowing an attacker on the local network to mount a timing attack to determine the AJP secret, which may lead to unauthorized access or other security bypasses...

Moderate: Red Hat Security Advisory: tomcat security, bug fix, and enhancement update

An update for tomcat is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from the...

org.apache.tomcat/tomcat-juli: tomcat: Apache Tomcat: console manipulation

An improper input neutralization flaw has been discovered in Apache Tomcat. Tomcat did not escape ANSI escape sequences in log messages. If Tomcat was running in a console on a Windows operating system, and the console supported ANSI escape sequences, it was possible for an attacker to use a...

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: DoS in examples web application

A flaw was found in the "examples" web application of Apache Tomcat. Numerous examples within that application did not place limits on uploaded data. This vulnerability can potentially trigger an out-of-memory OOM error, leading to a denial of service...

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,...

Apache Tomcat: Apache Tomcat: Authentication bypass due to CLIENT_CERT soft fail misconfiguration

A flaw was found in Apache Tomcat and Apache Tomcat Native. When CLIENTCERT authentication is configured with "soft fail" disabled, the authentication process may not correctly fail in certain scenarios. This vulnerability could allow an attacker to bypass expected client certificate...

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-coyote: Apache Tomcat: Authentication bypass via digest authentication

A flaw was found in Apache Tomcat. When DIGEST authentication was configured, any user not known to the configured Realm would be authenticated if they presented the password "null". This allows a remote attacker to bypass security controls...

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: 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: 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...
