Upgrade to the latest version of Apache Tomcat. These issues reduced the security of DIGEST authentication making replay attacks possible in some circumstances.Īffected Apache Tomcat versions (7.0.0 - 7.0.31). The user name and password were not checked before when indicating that a nonce was stale. When a session ID was present, authentication was bypassed. Tomcat tracked client rather than server nonces and nonce count. Three weaknesses in Tomcat's implementation of DIGEST authentication were identified and resolved: DIGEST authentication weakness CVE-2012-3439.When using FORM authentication it was possible to bypass the security constraint checks in the FORM authenticator by appending /j_security_check to the end of the URL if some other component (such as the Single-Sign-On valve) had called tUserPrincipal() before the call to FormAuthenticator#authenticate(). Important: Bypass of security constraints CVE-2012-3546.The vulnerability resides in the way specially crafted log messages were handled by the Log4j processor. Hence, we highly recommend to upgrade to the Apache Tomcat 10.0.7, 9.0.48, 8.5.68 versions or to the latest version of Apache Tomcat.The following problems were fixed in Apache Tomcat version 7.0.30: On December 6, 2021, Apache released version 2.15.0 of their Log4j framework, which included a fix for CVE-2021-44228, a critical (CVSSv3 10) remote code execution (RCE) vulnerability affecting Apache Log4j 2.14.1 and earlier versions. The vulnerability has been discovered in the current year but it’s been prevalent and observed frequently. Once the vulnerability is successfully detected by Qualys WAS, users shall see similar kind of results in the vulnerability scan report: Solution This request helps in retrieving the installed version of Apache Tomcat in the banner of the response. msfconsole, as shown in Figure 10.5: Scanning for port 8180 (Apache Tomcat) for getting. We make a request to GET /QUALYSTESTRANDOM.1tmhl HTTP/1.0. Vulnerability Assessment and Attack Simulation on Web, Mobile. This vulnerability is detected based on the installed version. Detecting vulnerability with Qualys WASĬustomers can detect this vulnerability with Qualys Web Application Scanning using QID 150367. Apache Tomcat has known remote code execution vulnerabilities resulting from a flaw that exploits the Tomcat PersistenceManager and FileStore components. Specifically – Tomcat incorrectly ignored the transfer encoding header if the client declared it would only accept an HTTP/1.0 response Tomcat honored the identify encoding but did not ensure that, if present, the chunked encoding was the final encoding. The potential for the vulnerability is a high possibility when the server is configured with a reverse proxy. Not parsing the request header based on the specification leads to the possibility to request smuggling. This vulnerability occurs because vulnerable versions of Apache tomcat do not correctly parse the HTTP transfer-encoding request header in some circumstances. About CVE-2021-33037Īpache Tomcat is an open source web server and servlet container developed by the Apache Software Foundation.Īccording to CVE-2021-33037, Apache tomcat versions 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 are vulnerable to this vulnerability. Qualys highly recommends upgrading all affected instances of Tomcat. Once detected, the vulnerability can be remediated by upgrading to Apache Tomcat 10.0.7, 9.0.48, 8.5.68 versions or to the latest version of Apache Tomcat. Qualys Web Application Scanning has added a new QID that detects this vulnerability by sending a request to the target server to determine if it is exploitable. Each vulnerability is given a security impact rating by the Apache Tomcat security team please note that this rating may vary from platform to platform. HTTP Request Smuggling (HRS) is a web application vulnerability that enables an attacker to craft a single request that hides a second request within the body of the first request. This page lists all security vulnerabilities fixed in released versions of Apache Tomcat 9.x. A vulnerability (CVE-2021-33037) discovered this year in Apache Tomcat causes incorrect parsing of the HTTP transfer-encoding request header in some circumstances, leading to the possibility of HTTP Request Smuggling (HRS) when used with a reverse proxy.
