Description

In mtee, there is a possible escalation of privilege due to type confusion. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS11383899; Issue ID: MSV-9608.

  "executiveSummary": "A type confusion vulnerability exists in the mtee component, potentially allowing for local privilege escalation.\nThe vulnerability occurs when the software processes data incorrectly, misinterpreting object types, which may lead to unauthorized memory access or control flow manipulation.\nThis issue carries significant risk for the integrity and confidentiality of the system, as successful exploitation could grant an attacker elevated privileges beyond their current scope.\nThe vulnerability requires that a malicious actor has already obtained System privilege or an equivalent level of access to trigger the exploit.\nNo user interaction is required for the successful execution of an attack once the prerequisite access is achieved.\nThis vulnerability is identified by Issue ID: MSV-9608 and Patch ID: ALPS11383899.",
  "technicalDetails": "The vulnerability resides within the mtee component, specifically stemming from a failure in type safety mechanisms. Type confusion occurs when the application allocates a resource of one type but subsequently accesses or processes it as if it were of a different type.\nIn this scenario, the root cause is a flawed validation or casting process where the internal representation of an object is mismatched with its intended usage. When an attacker provides crafted input or influences the state of the system, they can force the application to treat an object incorrectly. This leads to undefined behavior, which, when exploited, allows the attacker to corrupt memory, bypass security checks, or hijack execution flow.\nThe exploitation flow initiates from a context where the attacker has already achieved System-level privileges. By interacting with the vulnerable mtee interface, the attacker supplies specially crafted data designed to trigger the type confusion logic. Because the application fails to verify the object type before operations are performed, the misidentified object allows for out-of-bounds memory access or the execution of arbitrary code within the context of the vulnerable process.\nGiven that the vulnerability involves type confusion, the payload behavior is likely focused on exploiting the misaligned data pointers or object structures to read from or write to arbitrary memory locations. By successfully overwriting function pointers or sensitive kernel/user-mode structures, an attacker can transition from their initial privileged state to higher or more persistent levels of system control.\nThe scope of this vulnerability is localized, as it requires prior System-level access for successful exploitation, making it a post-exploitation escalation vector rather than a remote entry point. The impact is significant, as it effectively removes security boundaries that would otherwise contain or restrict the capabilities of a user, even one already holding System privileges. The lack of requirement for user interaction ensures that the attack can be automated by malicious actors once the initial access threshold is met."
