Siemens Teamcenter XSS and Hardcoded Key Vulnerabilities (SSA-827383)

high Nessus Plugin ID 314972

Language:

Synopsis

The remote host is missing one or more security updates.

Description

The version of Siemens Teamcenter installed on the remote host is affected by multiple vulnerabilities:

 - The affected application does not properly encode or filter user-supplied data. This could allow an attacker to inject malicious code that can be executed by other users when they visit the affected page. (CVE-2026-33862)

 - The affected application contains a hardcoded key which is used for obfuscation stored directly into the application. This could allow an attacker to obtain these keys and misuse them to gain unauthorized access. (CVE-2026-33893)

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

Solution

Upgrade to Siemens Teamcenter version 2312.0014, 2406.0012, 2412.0009, 2506.0005, or later.
