November 13, 2024
tomcat9 vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
Summary:
Several security issues were fixed in Tomcat.
Software Description:
- tomcat9: Servlet and JSP engine
Details:
It was discovered that Tomcat did not include the secure attribute for
session cookies when using the RemoteIpFilter with requests from a
reverse proxy. An attacker could possibly use this issue to leak
sensitive information. (CVE-2023-28708)
It was discovered that Tomcat had a vulnerability in its FORM
authentication feature, leading to an open redirect attack. An attacker
could possibly use this issue to perform phishing attacks. (CVE-2023-41080)
It was discovered that Tomcat incorrectly recycled certain objects,
which could lead to information leaking from one request to the next.
An attacker could potentially use this issue to leak sensitive
information. (CVE-2023-42795)
It was discovered that Tomcat incorrectly handled HTTP trailer headers. A
remote attacker could possibly use this issue to perform HTTP request
smuggling. (CVE-2023-45648)
It was discovered that Tomcat incorrectly handled socket cleanup, which
could lead to websocket connections staying open. An attacker could
possibly use this issue to cause a denial of service. (CVE-2024-23672)

Improper Input Validation vulnerability in Apache Tomcat. Tomcat from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly parse HTTP trailer headers. A specially crafted, invalid trailer header could cause Tomcat to treat a single request as multiple requests leading to the possibility of request smuggling when behind a reverse proxy. Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fix the issue.

Incomplete Cleanup vulnerability in Apache Tomcat. When recycling various internal objects in Apache Tomcat from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.80 and from 8.5.0 through 8.5.93, an error could cause Tomcat to skip some parts of the recycling process leading to information leaking from the current request/response to the next. Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fixes the issue.

Debian Linux Security Advisory 5381-1 - Several security vulnerabilities have been discovered in the Tomcat servlet and JSP engine.
When using the RemoteIpFilter with requests received from a reverse proxy via HTTP that include the X-Forwarded-Proto header set to https, session cookies created by Apache Tomcat 11.0.0-M1 to 11.0.0.-M2, 10.1.0-M1 to 10.1.5, 9.0.0-M1 to 9.0.71 and 8.5.0 to 8.5.85 did not include the secure attribute. This could result in the user agent transmitting the session cookie over an insecure channel.

Remote code execution is possible with Apache Tomcat before 6.0.48, 7.x before 7.0.73, 8.x before 8.0.39, 8.5.x before 8.5.7, and 9.x before 9.0.0.M12 if JmxRemoteLifecycleListener is used and an attacker can reach JMX ports. The issue exists because this listener wasn't updated for consistency with the CVE-2016-3427 Oracle patch that affected credential types.

The code in Apache Tomcat 9.0.0.M1 to 9.0.0.M11, 8.5.0 to 8.5.6, 8.0.0.RC1 to 8.0.38, 7.0.0 to 7.0.72, and 6.0.0 to 6.0.47 that parsed the HTTP request line permitted invalid characters. This could be exploited, in conjunction with a proxy that also permitted the invalid characters but with a different interpretation, to inject data into the HTTP response. By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack and/or obtain sensitive information from requests other then their own.
