What is CWE-1269?
This vulnerability occurs when a product ships to customers while still configured with its pre-production or manufacturing settings, which typically include powerful debugging and testing features not intended for real-world use.
Products under development or in manufacturing are configured with extensive debug capabilities to aid engineers. These often include backdoors to bypass security checks (like authentication or encryption), commands to read or modify internal memory and registers, hidden administrative functions, and the ability to alter critical system configurations. These features, while necessary for testing, create severe security gaps if they remain accessible after the product ships.
The risk is especially high in complex supply chains involving multiple vendors. For example, a chip manufacturer might test a component and then send it to an OEM for further testing before final production. The product is only considered secure for release after all testing is complete and a final lock-down step (like blowing a 'Manufacturing Complete' fuse) is performed. If this final step is missed, the product remains in its vulnerable, high-access manufacturing state, exposing end-users to potential attacks.
Impacto en el mundo real
Real-world CVEs caused by CWE-1269
-
Regarding SSA-686531, a hardware based manufacturing access on S7-1200 and S7-200 SMART has occurred. A vulnerability has been identified in SIMATIC S7-1200 CPU family (incl. SIPLUS variants) (All versions), SIMATIC S7-200 SMART CPU family (All versions). There is an access mode used during manufacturing of S7-1200 CPUs that allows additional diagnostic functionality. The security vulnerability could be exploited by an attacker with physical access to the UART interface during boot process. At the time of advisory publication, no public exploitation of this security vulnerability was known.
-
Laptops with Intel chipsets were found to be running in Manufacturing Mode. After this information was reported to the OEM, the vulnerability (CVE-2018-4251) was patched disallowing access to the interface.
Cómo lo explotan los atacantes
Ruta del atacante paso a paso
- 1
Identifica una ruta de código que maneje entrada no confiable sin validación.
- 2
Crea un payload que ejercite el comportamiento inseguro — inyección, traversal, overflow o abuso de lógica.
- 3
Envía el payload a través de una solicitud normal y observa la reacción de la aplicación.
- 4
Itera hasta que la respuesta filtre datos, ejecute código del atacante o escale privilegios.
Ejemplo de código vulnerable
Vulnerable Other
This example shows what happens when a preproduction system is made available for production.
Suppose the chipmaker has a way of scanning all the internal memory (containing chipmaker-level secrets) during the manufacturing phase, and the way the chipmaker or the Original Equipment Manufacturer (OEM) marks the end of the manufacturing phase is by blowing a Manufacturing Complete fuse. Now, suppose that whoever blows the Manufacturing Complete fuse inadvertently forgets to execute the step to blow the fuse. Ejemplo de código seguro
Secure Other
An attacker will now be able to scan all the internal memory (containing chipmaker-level secrets).
Blow the Manufacturing Complete fuse. What changed: the unsafe sink is replaced (or the input is validated/escaped) so the same payload no longer triggers the weakness.
Lista de prevención
How to prevent CWE-1269
- Implementation Ensure that there exists a marker for denoting the Manufacturing Complete stage and that the Manufacturing Complete marker gets updated at the Manufacturing Complete stage (i.e., the Manufacturing Complete fuse gets blown).
- Integration Ensure that there exists a marker for denoting the Manufacturing Complete stage and that the Manufacturing Complete marker gets updated at the Manufacturing Complete stage (i.e., the Manufacturing Complete fuse gets blown).
- Manufacturing Ensure that there exists a marker for denoting the Manufacturing Complete stage and that the Manufacturing Complete marker gets updated at the Manufacturing Complete stage (i.e., the Manufacturing Complete fuse gets blown).
