Definição
What is CWE-1263?
This vulnerability occurs when a device or system has areas meant to be physically secure, but the safeguards in place are too weak to stop someone with direct physical access from reaching restricted components or data.
Physical security flaws happen when the locks, seals, enclosures, or tamper-proofing on a device are not strong enough for its intended use. A consumer router, a medical implant, and an industrial control panel all need different levels of protection. Choosing the right physical barrier—like a robust casing or tamper-evident seals—is the first critical step in the design process.
However, selecting a good mechanism isn't enough; it must be correctly implemented during manufacturing and assembly. A weak point, such as a poorly installed screw or an easily bypassed panel, can render the entire protection scheme useless. Ultimately, physical security fails when the design, implementation, and production do not work together to create a unified defense against hands-on tampering.

Como os atacantes a exploram
Trajeto do atacante passo a passo
- 1
Identificar um caminho de código que trata input não confiável sem validação.
- 2
Criar um payload que explora o comportamento inseguro — injeção, traversal, overflow ou abuso de lógica.
- 3
Entregar o payload através de um pedido normal e observar a reação da aplicação.
- 4
Iterar até que a resposta exponha dados, execute código do atacante ou escale privilégios.
Exemplo de código vulnerável
Vulnerable pseudo
A MITRE não publicou um exemplo de código para este CWE. O padrão abaixo é ilustrativo — consulte os Recursos para referências canónicas.
// Example pattern — see MITRE for the canonical references.
function handleRequest(input) {
// Untrusted input flows directly into the sensitive sink.
return executeUnsafe(input);
} Exemplo de código seguro
Secure pseudo
// Validate, sanitize, or use a safe API before reaching the sink.
function handleRequest(input) {
const safe = validateAndEscape(input);
return executeWithGuards(safe);
} What changed: the unsafe sink is replaced (or the input is validated/escaped) so the same payload no longer triggers the weakness.
Lista de verificação de prevenção
How to prevent CWE-1263
- Architecture and Design Specific protection requirements depend strongly on contextual factors including the level of acceptable risk associated with compromise to the product's protection mechanism. Designers could incorporate anti-tampering measures that protect against or detect when the product has been tampered with.
- Testing The testing phase of the lifecycle should establish a method for determining whether the protection mechanism is sufficient to prevent unauthorized access.
- Manufacturing Ensure that all protection mechanisms are fully activated at the time of manufacturing and distribution.

Como posso prevenir o CWE-1263?
Specific protection requirements depend strongly on contextual factors including the level of acceptable risk associated with compromise to the product's protection mechanism. Designers could incorporate anti-tampering measures that protect against or detect when the product has been tampered with. The testing phase of the lifecycle should establish a method for determining whether the protection mechanism is sufficient to prevent unauthorized access.
