Due to a mistake in libcurl's WebSocket code, a malicious server can send a particularly crafted packet which makes libcurl get trapped in an endless busy-loop. There is no other way for the application to escape or exit this loop other than killing the thread/process. This might be used to DoS libcurl-using application.

The version of Tenable.ad installed on the remote host is prior to 3.77.12. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2025-14 advisory.

  - Due to a mistake in libcurl's WebSocket code, a malicious server can send a particularly crafted packet which     makes libcurl get trapped in an endless busy-loop. There is no other way for the application to escape or exit     this loop other than killing the thread/process. (CVE-2025-5399) 

  - Untrusted search path in .NET and Visual Studio allows an unauthorized attacker to execute code over a     network. (CVE-2025-30399)

  - libcurl accidentally skips the certificate verification for QUIC connections when connecting to a host specified     as an IP address in the URL. Therefore, it does not detect impostors or man-in-the-middle attacks. (CVE-2025-4947)

The versions of MySQL Server installed on the remote host are affected by a multiple vulnerabilities as referenced in the July 2025 CPU advisory.

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer).  Supported versions that     are affected are 8.0.0-8.0.42, 8.4.0-8.4.5 and  9.0.0-9.3.0. Easily exploitable vulnerability allows high privileged     attacker with network access via multiple protocols to compromise MySQL Server.  Successful attacks of this     vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of     MySQL Server. (CVE-2025-50101)
