Technical Analysis
This vulnerability arises from improper integer handling in the cobs_decode function of the SpaceDot AcubeSAT On-Board Computer (OBC) software at commit eaf90ec. An attacker physically proximate to the device with UART access can send specially crafted input to trigger a Denial of Service, disrupting normal operation. The CVSS v3.1 base score is 7.5, reflecting high severity due to the network attack vector with low complexity and no privileges or user interaction required. The flaw is categorized under CWE-400, indicating a resource exhaustion or DoS condition. No patch or remediation information is currently available, and no known exploits are reported in the wild.
Potential Impact
Successful exploitation results in a Denial of Service (DoS) on the affected device, impacting availability. There is no reported impact on confidentiality or integrity. The attack requires physical proximity and UART access, limiting the attack surface.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict physical access to UART interfaces and monitor for unusual activity on these ports.
