curl's websocket code did not update the 32 bit mask pattern for each new outgoing frame as the specification says. Instead it used a fixed mask that persisted and was used throughout the entire connection. A predictable mask pattern allows for a malicious server to induce traffic between the two communicating parties that could be interpreted by an involved proxy (configured or transparent) as genuine, real, HTTP traffic with content and thereby poison its cache. That cached poisoned content could then be served to all users of that proxy.

An update of the curl package has been released.

The version of Tenable Identity Exposure (formerly Tenable.ad) installed on the remote host is prior to 3.77.14. It therefore contains vulnerable versions of third-party components (.NET, SQL Server, and curl). Tenable has upgraded these components to address the potential impact of the issues, including the following:

  - Inconsistent interpretation of HTTP requests ('HTTP request/response smuggling') in ASP.NET Core allows an     authorized attacker to bypass a security feature over a network. (CVE-2025-55315)

  - Use of uninitialized resource in SQL Server allows an unauthorized attacker to disclose information over a network.     (CVE-2025-49718)

  - A cookie is set using the `secure` keyword for `https://target`. Curl is redirected to or otherwise made to speak     with `http://target` (same hostname, but using clear text HTTP) using the same cookie set. The same cookie name is     set - but with just a slash as path (`path='/'`). Since this site is not secure, the cookie should just be     ignored. A bug in the path comparison logic makes curl read outside a heap buffer boundary. The bug either causes a     crash or it potentially makes the comparison come to the wrong conclusion and lets the clear-text site override the     contents of the secure cookie, contrary to expectations and depending on the memory contents immediately following     the single-byte allocation that holds the path. (CVE-2025-9086)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Oracle Essbase installed on the remote host is missing a security patch from the October 2025 Critical Patch Update (CPU). It is, therefore, affected by:

  - Vulnerability in Oracle Essbase (component: Security and Provisioning (Bouncy Castle Java Library)). The     supported version that is affected is 21.7.3.0.0. Easily exploitable vulnerability allows unauthenticated     attacker with network access via HTTPS to compromise Oracle Essbase. Successful attacks of this     vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of     Oracle Essbase. (CVE-2025-8916)

  - Vulnerability in Oracle Essbase (component: Security and Provisioning (Nimbus JOSE+JWT)). The supported     version that is affected is 21.7.3.0.0. Easily exploitable vulnerability allows unauthenticated attacker     with network access via HTTP to compromise Oracle Essbase. While the vulnerability is in Oracle Essbase,     attacks may significantly impact additional products (scope change). Successful attacks of this     vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of     Oracle Essbase. (CVE-2025-53864)

  - Vulnerability in Oracle Essbase (component: Essbase Web Platform). The supported version that is     affected is 21.7.3.0.0. Easily exploitable vulnerability allows low privileged attacker with network     access via HTTP to compromise Oracle Essbase. Successful attacks of this vulnerability can result in     unauthorized creation, deletion or modification access to critical data or all Oracle Essbase accessible     data as well as unauthorized access to critical data or complete access to all Oracle Essbase accessible     data. (CVE-2025-61763)   Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
