CVE-2024-44102

CVSS 10.0v4.0pub. 2024-11-12upd. 2024-11-13

A vulnerability has been identified in PP TeleControl Server Basic 1000 to 5000 V3.1 (6NH9910-0AA31-0AE1) (All versions < V3.1.2.1 with redundancy configured), PP TeleControl Server Basic 256 to 1000 V3.1 (6NH9910-0AA31-0AD1) (All versions < V3.1.2.1 with redundancy configured), PP TeleControl Server Basic 32 to 64 V3.1 (6NH9910-0AA31-0AF1) (All versions < V3.1.2.1 with redundancy configured), PP TeleControl Server Basic 64 to 256 V3.1 (6NH9910-0AA31-0AC1) (All versions < V3.1.2.1 with redundancy configured), PP TeleControl Server Basic 8 to 32 V3.1 (6NH9910-0AA31-0AB1) (All versions < V3.1.2.1 with redundancy configured), TeleControl Server Basic 1000 V3.1 (6NH9910-0AA31-0AD0) (All versions < V3.1.2.1 with redundancy configured), TeleControl Server Basic 256 V3.1 (6NH9910-0AA31-0AC0) (All versions < V3.1.2.1 with redundancy configured), TeleControl Server Basic 32 V3.1 (6NH9910-0AA31-0AF0) (All versions < V3.1.2.1 with redundancy configured), TeleControl Server Basic 5000 V3.1 (6NH9910-0AA31-0AE0) (All versions < V3.1.2.1 with redundancy configured), TeleControl Server Basic 64 V3.1 (6NH9910-0AA31-0AB0) (All versions < V3.1.2.1 with redundancy configured), TeleControl Server Basic 8 V3.1 (6NH9910-0AA31-0AA0) (All versions < V3.1.2.1 with redundancy configured), TeleControl Server Basic Serv Upgr (6NH9910-0AA31-0GA1) (All versions < V3.1.2.1 with redundancy configured), TeleControl Server Basic Upgr V3.1 (6NH9910-0AA31-0GA0) (All versions < V3.1.2.1 with redundancy configured). The affected system allows remote users to send maliciously crafted objects. Due to insecure deserialization of user-supplied content by the affected software, an unauthenticated attacker could exploit this vulnerability by sending a maliciously crafted serialized object. This could allow the attacker to execute arbitrary code on the device with SYSTEM privileges.

🤖 AI Analysis

How it works

The attacker sends a specially crafted malicious serialized object over the network to the vulnerable system without the need for authentication. The software deserializes the received data without proper validation (CWE-502 — insecure deserialization), allowing injection and execution of arbitrary code. Execution occurs in the context of the SYSTEM account, granting the attacker full administrative privileges on the host.

Impact

An unauthenticated attacker can take full control of the server by executing arbitrary code with SYSTEM privileges — which in an industrial environment can lead to disruption or takeover of telemetry and control processes.

Mitigation & patch

Software must be updated to version V3.1.2.1 or later. Detailed update instructions are available in the Siemens security bulletin SSA-454789 at: https://cert-portal.siemens.com/productcert/html/ssa-454789.html. Until the patch is deployed, it is recommended to restrict network access to the server via firewall and implement OT network segmentation.

Who is affected

All versions below V3.1.2.1 with configured redundancy for the following V3.1 product line: TeleControl Server Basic 8, 32, 64, 256, 1000, 5000 (catalog numbers 6NH9910-0AA31-0AA0 to 0AE0), corresponding PP TeleControl Server Basic variants (6NH9910-0AA31-0AB1 to 0AF1) and TeleControl Server Basic Serv Upgr and Upgr V3.1 (6NH9910-0AA31-0GA0/0GA1)
