**Name of the Vulnerable Software and Affected Versions** Apache Traffic Server versions 9.0.0 through 9.2.14 Apache Traffic Server versions 10.0.0 through 10.1.3 **Description** An issue exists involving the inconsistent interpretation of HTTP requests, known as HTTP Request/Response Smuggling. This occurs due to the parsing of quoted-strings within chunked extensions. **Recommendations** Upgrade Apache Traffic Server versions 9.0.0 through 9.2.14 to version 9.2.15. Upgrade Apache Traffic Server versions 10.0.0 through 10.1.3 to version 10.1.4.

**Name of the Vulnerable Software and Affected Versions** Apache Traffic Server versions 8.0.0 through 8.1.9 Apache Traffic Server versions 9.0.0 through 9.2.14 Apache Traffic Server versions 10.0.0 through 10.1.3 **Description** Apache Traffic Server is susceptible to request smuggling, a technique where an attacker interferes with the way a website and its proxy server process sequences of HTTP requests, when chunked messages are malformed. **Recommendations** Upgrade versions 8.0.0 through 9.2.14 to version 9.2.15. Upgrade versions 10.0.0 through 10.1.3 to version 10.1.4.

Name of the Vulnerable Software and Affected Versions Apache Traffic Server versions 9.0.0 through 9.2.12 and 10.0.0 through 10.1.1 Description Apache Traffic Server is susceptible to request smuggling when handling malformed chunked messages. This can potentially lead to various security issues. Recommendations Upgrade to version 9.2.13 or 10.1.2.

**Name of the Vulnerable Software and Affected Versions** Apache Traffic Server versions through 9.2.1 **Description** The issue is caused by improper input validation in the Range Header Handler component of the Apache Traffic Server. This can be exploited by a remote attacker to cause a denial of service. **Recommendations** For versions through 9.2.1, update to a version later than 9.2.1 to resolve the issue. As a temporary workaround, consider restricting access to the Range Header Handler component until a patch is available.

**Name of the Vulnerable Software and Affected Versions** Apache Traffic Server versions 7.0.0 through 7.1.12 Apache Traffic Server versions 8.0.0 through 8.1.1 Apache Traffic Server versions 9.0.0 through 9.0.1 **Description** The issue is caused by improper input validation in the HTTP/2 component of Apache Traffic Server. This allows a remote attacker to cause a denial of service. **Recommendations** For Apache Traffic Server versions 7.0.0 through 7.1.12, update to a version outside of this range to resolve the issue. For Apache Traffic Server versions 8.0.0 through 8.1.1, update to a version outside of this range to resolve the issue. For Apache Traffic Server versions 9.0.0 through 9.0.1, update to a version outside of this range to resolve the issue. As a temporary workaround, consider restricting access to the HTTP/2 component until a patch is available.
