CA Automic Applications Manager (AM)

Issue/Introduction

Security scanners may report Applications Manager's webserver to be using a version of Jetty that is vulnerable to CVE-2025-11143.

Jetty can interpret certain invalid or unusual URIs (using odd schemes, IPv6/host delimiter edge cases, or specific priority for #, ?, or @ delimiters) differently than common parsers like those found in reverse proxies, load balancers, WAFs, or API gateways.

Exploitation typically requires the following conditions:

  1. Vulnerable Jetty version in the request path.
  2. Multiple URI parsers (e.g., a proxy and Jetty) interpreting the same request.
  3. Security-relevant divergence, where the mismatch allows an attacker to bypass an authorization blocklist or causes information disclosure.
  4. Attacker-controlled request line providing malformed URIs.

 

Environment

Applications Manager 9.6.2

Cause

In version 9.6.2, Applications Manager uses Jetty 11.0.26 as part of the integrated webserver

Resolution

Why AM is not exploitable:

  1. Single stack — Routing and static serving are handled by Jetty’s normal pipeline; AM code does not add another URL parser that could disagree with Jetty on malformed URIs for allow/deny or routing.
  2. No blacklist / policy engine on raw URLs — Nothing in code matches “block path X” using a different library than Jetty.
  3. Error page — Uses Jetty/servlet error attributes; redirect targets are built from fixed config + known homePageUrl, not from re-parsing the client’s raw request line in a separate URI implementation.
    Hence, for the embedded static webserver as shipped with AM 9.6.2, AM code does not layer a second URI policy engine on top of Jetty, so the differential-parsing attack class does not apply in the way described.

While not vulnerable, in version 9.6.3, a fixed jetty version for Spring based webserver will be included (which will come into effect only when APIs are enabled).
