Exploitability

CWE

KEV

CWE ID	Description
CWE-1294	The System-on-Chip (SoC) implements a Security Identifier mechanism to differentiate what actions are allowed or disallowed when a transaction originates from an entity. However, the Security Identifiers are not correctly implemented.

Attack-Flow Graph

Executive Summary

This vulnerability involves a weak configuration where a user equipment (UE) fails to verify the consistency of its additional security capabilities with the replayed capabilities. This could allow an attacker to exploit the inconsistency to bypass security measures.

Detection Guidance

This vulnerability involves inconsistent security capabilities verification in UE (User Equipment). Detection requires analyzing network traffic for capability mismatches between initial and replayed messages. Use protocol analyzers like Wireshark to inspect UE capability exchange messages in 4G/5G signaling traffic. Look for discrepancies in security feature advertisements between original and replayed messages. No specific commands are provided in the context.

Impact Analysis

An attacker could exploit this to gain unauthorized access or intercept sensitive information by manipulating security capabilities. The high CVSS score (7.5) indicates significant potential impact on confidentiality.

Compliance Impact

This vulnerability could lead to unauthorized data access or breaches, violating GDPR (data protection) and HIPAA (health information privacy) requirements. Non-compliance may result in legal penalties or reputational damage.

Mitigation Strategies

Update or reconfigure the UE (User Equipment) to ensure it verifies the consistency of additional security capabilities with replayed capabilities. Apply patches or firmware updates from the vendor if available.
