Overview<\/strong><\/p>\n

A critical vulnerability, CVE-2025-30175, has been identified in multiple versions of SIMATIC PCS neo, SINEC NMS, SINEMA Remote Connect, Totally Integrated Automation Portal (TIA Portal), and User Management Component (UMC). The vulnerability is of high concern due to the potential for system compromise or data leakage, and it could allow an unauthenticated remote attacker to cause a denial of service condition.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-30175
\nSeverity: High (7.5 CVSS)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise and potential data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

SIMATIC PCS neo | V4.1, V5.0
\nSINEC NMS | All versions
\nSINEMA Remote Connect | All versions
\nTIA Portal | V17, V18, V19, V20
\nUser Management Component (UMC) | All versions < V2.15.1.1\n\nHow the Exploit Works<\/strong><\/p>\n

The exploit takes advantage of an out of bounds write buffer overflow vulnerability in the integrated UMC component of the affected products. An unauthenticated, remote attacker could send specially crafted data to the targeted system, causing the system to write data beyond the boundaries of allocated memory buffers. This could lead to a denial of service condition or potentially allow the attacker to execute arbitrary code.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

A conceptual example of the exploit might look like this:<\/p>\n

POST \/UMCcomponent\/endpoint HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"buffer_overflow_payload\": \"AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA...\" }<\/code><\/pre>\n
The “buffer_overflow_payload” in the example contains an unusually large amount of data, specifically designed to overflow the allocated memory buffer and exploit the vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"
