The vulnerability identified as CVE-2024-56189 resides within the SAEMM_DiscloseMsId function of the SAEMM_RadioMessageCodec.c file, representing a critical out-of-bounds read flaw that compromises system security. This issue manifests when the software fails to validate array indices before accessing memory locations, creating a potential avenue for unauthorized data extraction. The vulnerability specifically affects systems implementing the SAEMM (Satellite and Earth Station Management Module) radio message codec functionality, where proper bounds checking mechanisms are absent during message processing operations.
The technical implementation flaw stems from inadequate input validation within the radio message decoding process, where the SAEMM_DiscloseMsId function processes incoming message identifiers without proper boundary verification. This condition creates an exploitable scenario where an authenticated attacker can manipulate message parameters to access memory regions beyond the intended array boundaries. The vulnerability operates at the application layer and specifically targets memory access patterns within the radio message codec component, making it particularly dangerous for systems that handle sensitive communication data. According to CWE standards, this represents a classic instance of CWE-129: Improper Validation of Array Index, which directly correlates to the missing bounds check vulnerability.
The operational impact of CVE-2024-56189 extends beyond simple information disclosure, as it enables remote attackers to extract potentially sensitive data from system memory without requiring additional privileges or execution capabilities. The authentication requirement for exploitation indicates that the vulnerability exists within a system that requires legitimate user credentials to access, but once authenticated, the attacker can leverage this flaw to gain unauthorized access to data that should remain protected. This vulnerability operates under the ATT&CK framework as a privilege escalation technique, specifically categorized under T1068: Exploitation for Privilege Escalation, where the attacker can leverage existing access to extract additional information. The lack of user interaction requirements makes this vulnerability particularly concerning as it can be exploited automatically without requiring any additional user engagement or specific conditions.
Systems utilizing the SAEMM radio message codec functionality are at risk of information disclosure, potentially exposing sensitive communication data, system configuration details, or proprietary information contained within memory buffers. The vulnerability's remote exploitation capability means that attackers can target systems from external networks without requiring physical access or additional attack vectors. Mitigation strategies should include immediate code review and implementation of proper bounds checking mechanisms within the SAEMM_RadioMessageCodec.c file, specifically within the SAEMM_DiscloseMsId function. Security patches should enforce array index validation before memory access operations, ensuring that all message parameter values fall within acceptable ranges before processing. Organizations should also implement network segmentation and monitoring controls to detect anomalous message processing patterns that might indicate exploitation attempts, while maintaining regular security assessments to identify similar vulnerabilities within the codebase.
