|---|---|---|---|---|---|---|
| October 2023 | When recycling various internal objects, including the request and the response, prior to re-use by the next request/response, 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. |
| Upgrade to latest version of Apache Tomcat. Note: Delft-FEWS releases < 2023.01 require Apache Tomcat 9, release >= 2023.01 require Apache Tomcat 10. | |||
| October 2023 | Tomcat's HTTP/2 implementation was vulnerable to the rapid reset attack. The denial of service typically manifested as an OutOfMemoryError. |
| Upgrade to latest version of Apache Tomcat. Note: Delft-FEWS releases < 2023.01 require Apache Tomcat 9, release >= 2023.01 require Apache Tomcat 10. | |||
| October 2023 | Tomcat 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. |
| Upgrade to latest version of Apache Tomcat. Note: Delft-FEWS releases < 2023.01 require Apache Tomcat 9, release >= 2023.01 require Apache Tomcat 10. | |||
| June 2023 | CVE-2023-34981 | A regression in the fix for bug 66512 in Apache Tomcat 11.0.0-M5, 10.1.8, 9.0.74 and 8.5.88 meant that, if a response did not include any HTTP headers no AJP SEND_HEADERS messare woudl be sent for the response which in turn meant that at least one AJP proxy (mod_proxy_ajp) would use the response headers from the previous request leading to an information leak. |
| None, we do not use AJP proxy | Upgrade to latest version of Apache Tomcat. Note: Delft-FEWS releases < 2023.01 require Apache Tomcat 9, release >= 2023.01 require Apache Tomcat 10. | |
| May 2023 | CVE-2022-28079 | The fix for CVE-2023-24998 was incomplete. If non-default HTTP connector settings were used such that the maxParameterCount could be reached using query string parameters and a request was submitted that supplied exactly maxParameterCount parameters in the query string, the limit for uploaded request parts could be bypassed with the potential for a denial of service to occur. |
| Upgrade to latest version of Apache Tomcat. Note: Delft-FEWS releases < 2023.01 require Apache Tomcat 9, release >= 2023.01 require Apache Tomcat 10. |
