The vulnerability allows an attacker to keep connections open and exhaust resources, with a CVSS v2 base score of 5.0 in the initial metric (note: other sources list base sc...

CVE-2012-4431

CVE-2012-4431 affects Apache Tomcat 6.x earlier than 6.0.36 and 7.x earlier than 7.0.32. The vulnerability resides in CsrfPreventionFilter, allowing remote attackers to bypass CSRF protection via a request that lacks a session identifier. The connected documents confirm the affected component pat...

CVE-2011-4858

CVE-2011-4858 affects Apache Tomcat 5.5.x before 5.5.35, 6.x before 6.0.35, and 7.x before 7.0.23. The issue arises from the Java hashCode() implementation allowing predictable hash collisions, enabling a remote attacker to exhaust CPU by sending many crafted parameters in a request (hash collisi...

CVE-2012-5887

The CVE-2012-5887 entry concerns the HTTP Digest Access Authentication in Apache Tomcat (versions 5.5.x before 5.5.36, 6.x before 6.0.36, 7.x before 7.0.30). The vulnerability is a failure to properly check stale nonce values when enforcing credentials, enabling remote attackers to bypass access ...

CVE-2011-1184

The vulnerability CVE-2011-1184 affects Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.12. The HTTP Digest Access Authentication implementation has insufficient replay-attack countermeasures due to lack of proper nonce and nc (nonce-count) checking, which can allow remot...

CVE-2012-0022

Apache Tomcat 5.5.x before 5.5.35, 6.x before 6.0.34, and 7.x before 7.0.23 are affected by a denial-of-service vulnerability caused by an inefficient handling of HTTP parameters that can be exploited by sending requests with many parameters. The root cause is a hash-collision vulnerability in pa...

CVE-2011-3375

CVE-2011-3375 affects Apache Tomcat 6.0.30–6.0.33 and 7.x before 7.0.22. The root cause is improper caching/recycling of request objects, which can allow remote attackers to read IP addresses and HTTP header information by reading TCP data. The impact is information disclosure of request metadata...

CVE-2012-3546

CVE-2012-3546 affects Apache Tomcat 6.x (before 6.0.36) and 7.x (before 7.0.30). The flaw, in RealmBase/FormAuthenticator when FORM authentication is used, lets remote attackers bypass security-constraint checks by leveraging a prior setUserPrincipal() and appending /j_security_check to the URL. ...

CVE-2012-4534

The CVE-2012-4534 issue affects Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.28. When using the NIO connector with sendfile over HTTPS, the NioEndpoint can enter an infinite loop if the client terminates the connection while reading a response, causing a denial of service. The root cause is...

CVE-2011-5064

The vulnerability CVE-2011-5064 affects Apache Tomcat’s HTTP Digest Access Authentication (DigestAuthenticator.java) where Catalina is used as the hard-coded server secret (private key). Affected are Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.12. This weakness enables remot...

CVE-2012-5885

Affected software: Apache Tomcat (5.5.x up to 5.5.36, 6.x up to 6.0.36, 7.x up to 7.0.30) using the HTTP Digest Access Authentication replay-countermeasure. Root cause: replay-countermeasure tracks cnonce values instead of server nonce and nonce-count, enabling bypass of access restrictions when ...

CVE-2011-5063

CVE-2011-5063 describes an issue in Apache Tomcat’s HTTP Digest Access Authentication where the realm values are not checked, enabling bypass of access controls by exploiting a protection space with weaker requirements (distinct from CVE-2011-1184). Related documents (CVE-2011-1184, CVE-2012-5885...

CVE-2012-5886

CVE-2012-5886 (Apache Tomcat) is an authentication bypass issue in the Digest Access Authentication implementation. It occurs because the HTTP Digest Auth stores information about the authenticated user in the session state, enabling remote attackers to bypass authentication by exploiting session...

CVE-2012-2733

CVE-2012-2733 involves Apache Tomcat’s HTTP NIO connector (java/org/apache/coyote/http11/InternalNioInputBuffer.java). The flaw does not properly restrict the request-header size in Tomcat 6.x before 6.0.36 and 7.x before 7.0.28, allowing remote attackers to trigger memory consumption and cause a...

CVE-2011-5062

CVE-2011-5062 affects Apache Tomcat’s HTTP Digest Access Authentication. The vulnerability arises because Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.12 do not check qop values, enabling remote attackers to bypass intended integrity protections via a qop=auth value. This is ...
