Each vulnerability is given a security impact rating by the development team - please note that this rating may vary from platform to platform. More than 1 million actively reachable servers on the internet are running Apache Tomcat. This page lists all security vulnerabilities fixed in released versions of Apache Commons FileUpload.
#APACHE TOMCAT VULNERABILITY SOFTWARE#
Vulnerable software versionsĪpache Tomcat: 8.5.38 - 10.1.0-M14 CPE2.3 Apache Tomcat has known remote code execution vulnerabilities resulting from a flaw that exploits the Tomcat PersistenceManager and FileStore components. A remote attacker can perform a denial of service attack against the exposed EncryptInterceptor. The vulnerability exists due to an error in documentation for the EncryptInterceptor, which incorrectly stated that it enabled Tomcat clustering to run over an untrusted network. Custom Servlets used as error pages must ensure that they handle any error dispatch as a GET request, regardless of the actual method.The vulnerability allows a remote attacker to perform DoS attack. (2) By default, the response generated by a Servlet does depend on the HTTP method. Apache Tomcat versions 11.0.0-M1 prior to 11.0.0-M3, 10.1.0-M1 prior to 10.1.6, 9.0.0 prior to 9.0.17, and 8.5.0 prior to 8.5. JSPs used as error pages must must ensure that they handle any error dispatch as a GET request, regardless of the actual method. Notes for other user provided error pages: (1) Unless explicitly coded otherwise, JSPs ignore the HTTP method. ESM enables continuous vulnerability management for critical, high and medium CVEs. The vulnerability resides in the way specially crafted log messages were handled by the Log4j processor.
#APACHE TOMCAT VULNERABILITY UPGRADE#
The object introduced to collect metrics for HTTP upgrade connections was not released for WebSocket connections once the connection was closed. Depending on the original request this could lead to unexpected and undesirable results for static error pages including, if the DefaultServlet is configured to permit writes, the replacement or removal of the custom error page. 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 fix for bug 63362 present in Apache Tomcat 10.1.0-M1 to 10.1.0-M5, 10.0.0-M1 to 10.0.11, 9.0.40 to 9.0.53 and 8.5.60 to 8.5.71 introduced a memory leak. Figure 9 shows the results on Apache Tomcat Connector (modjk).
The Default Servlet in Apache Tomcat 9.0.0.M1 to 9.0.0.M20, 8.5.0 to 8.5.14, 8.0.0.RC1 to 8.0.43 and 7.0.0 to 7.0.77 did not do this. The vulnerability is a boundary error within the prctrlsrecvrequest() function in the. If the error page is a static file, expected behaviour is to serve content of the file as if processing a GET request, regardless of the actual HTTP method. It is awaiting reanalysis which may result in further changes to the information provided. For example, an organization running a vulnerable apache tomcat server. CVE-2021-42340 Detail Description The fix for bug 63362 present in Apache Tomcat 10.1.0-M1 to 10.1.0-M5, 10.0.0-M1 to 10.0.11, 9.0.40 to 9.0.53 and 8.5.60 to 8.5.71 introduced a memory leak. This vulnerability has been modified since it was last analyzed by the NVD. This means that the request is presented to the error page with the original HTTP method. Vulnerability Vulnerability is defined as a flaw or a weakness inside the asset. The error page mechanism of the Java Servlet Specification requires that, when an error occurs and an error page is configured for the error that occurred, the original request and response are forwarded to the error page.
