Apache Tomcat 7.0.x < 7.0.55 Multiple Vulnerabilities

critical Nessus Plugin ID 77475
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Apache Tomcat server is affected by multiple vulnerabilities.

Description

According to its self-reported version number, the Apache Tomcat service listening on the remote host is 7.0.x prior to 7.0.55. It is, therefore, affected by the following vulnerabilities :

- A race condition exists in the ssl3_read_bytes() function when SSL_MODE_RELEASE_BUFFERS is enabled. This allows a remote attacker to inject data across sessions or cause a denial of service. (CVE-2010-5298)

- A buffer overflow error exists related to invalid DTLS fragment handling that can lead to the execution of arbitrary code. Note that this issue only affects OpenSSL when used as a DTLS client or server.
(CVE-2014-0195)

- An error exists in the do_ssl3_write() function that allows a NULL pointer to be dereferenced, resulting in a denial of service. Note that this issue is exploitable only if 'SSL_MODE_RELEASE_BUFFERS' is enabled.
(CVE-2014-0198)

- An error exists related to DTLS handshake handling that can lead to denial of service attacks. Note that this issue only affects OpenSSL when used as a DTLS client.
(CVE-2014-0221)

- An unspecified error exists in how ChangeCipherSpec messages are processed that can allow an attacker to cause usage of weak keying material, leading to simplified man-in-the-middle attacks. (CVE-2014-0224)

- An error exists in 'ChunkedInputFilter.java' due to improper handling of attempts to continue reading data after an error has occurred. This allows a remote attacker, via streaming data with malformed chunked transfer coding, to conduct HTTP request smuggling or cause a denial of service. (CVE-2014-0227)

- An error exists due to a failure to limit the size of discarded requests. A remote attacker can exploit this to exhaust available memory resources, resulting in a denial of service condition. (CVE-2014-0230)

- An unspecified error exists related to anonymous ECDH cipher suites that can allow denial of service attacks.
Note that this issue only affects OpenSSL TLS clients.
(CVE-2014-3470)

Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Tomcat version 7.0.55 or later.
