The Microsoft Visual Studio Products are missing security updates. It is, therefore, affected by multiple vulnerabilities:

  - Heap-based buffer overflow in .NET allows an unauthorized attacker to elevate privileges locally.   (CVE-2026-32177)

  - A tampering vulnerability exists when .NET Core improperly handles specially crafted files. An attacker   who successfully exploited this vulnerability could write arbitrary files and directories to certain   locations on a vulnerable system. However, an attacker would have limited control over the destination of   the files and directories. To exploit the vulnerability, an attacker must send a specially crafted file to   a vulnerable system. The security update fixes the vulnerability by ensuring .NET Core properly handles   files. (CVE-2026-32175)

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Heap-based buffer overflow in .NET allows an unauthorized attacker to elevate privileges locally.
    (CVE-2026-32177)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of Tenable Identity Exposure running on the remote host is prior to 3.93.5. It is, therefore, affected by multiple vulnerabilities according to advisory TNS-2026-16:

  - Tenable Identity Exposure contains multiple unauthenticated API endpoints under /w/api/* that expose     sensitive application configuration data including cleartext LDAP credentials, SAML configuration, user     accounts, and directory settings to unauthenticated remote attackers. Affected responses are served with     Cache-Control: public headers and without Vary: Cookie, allowing reverse proxies and CDNs to cache and     serve sensitive data to unauthenticated users even after authentication is applied. (CVE-2026-13007)

  - 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)

  - Converting an excessively large OCTET STRING value to a hexadecimal string leads to a heap buffer     overflow on 32 bit platforms. A heap buffer overflow may lead to a crash or possibly an attacker     controlled code execution or other undefined behavior. (CVE-2026-31789)

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

The Microsoft .NET Framework installation on the remote host is missing a security update. It is, therefore, affected by the following vulnerability:
